The 0% Victory: How One Importer Crushed a 9% + Agricultural Duty Trap

2026年4月6日 by TaichiKawazoe(河副 太智) Leave a Comment

In the high-stakes world of international trade and supply chain management, a single digit in an HS code can mean the difference between a highly profitable product line and a catastrophic financial loss.

This is the gripping, true story of a massive reversal—a scenario where an importer stared down the barrel of a devastating 9.00% + EA(1) duty rate, stood up against an unreasonable customs decision using a forgotten 16-year-old court precedent, and clawed their way back to a definitive 0% duty. It’s a masterclass in why you should never take a government ruling at face value, and how fighting back with hard legal evidence can lead to an explosion in profits.

The Sweet, Red Trap: A Simple Colorant Turned Nightmare
Our story begins in the supply chain trenches with a rather unassuming product: a slightly viscous, red liquid colorant.

Intended for industrial manufacturing, the product’s formulation was remarkably simple and entirely natural. The spec sheet read like a recipe for a healthy smoothie rather than a complex chemical compound:

Radish concentrate
Safflower concentrate
Lemon concentrate
Citric acid
Sucrose syrup (Sugar)

With the intention of importing this into the European Union, the importer did everything by the book. They applied for a Binding Tariff Information (BTI) decision from the Netherlands Customs authorities to secure legal certainty before shipping. The application confidently requested classification under HS Code 3203.00—the designated category for “Coloring matter of vegetable or animal origin.”

However, in 2019, the response from Customs sent shockwaves through the importer’s finance department.

The ruling was brutal: “This is not a colorant. Due to the amount of added sugar, it is a ‘Food Preparation’.”

Operating on a rigid, checklist mentality, the Customs laboratory had fixated entirely on the presence and volume of the “sucrose syrup.” Completely ignoring the product’s fundamental purpose and commercial reality—that it was exclusively used to dye other products, not to be consumed on its own—they shoved it into the catch-all category for food preparations: HS Code 2106.90.
NLBTI2019-0073

With that stroke of a pen, the duty rate skyrocketed to 9.00% + EA(1).

The “Agricultural Duty” Hell
To the uninitiated, treating a colorant as “food” might just sound like bureaucratic semantics. But in the EU, importing “food” that contains sugar or dairy is akin to walking through a financial minefield.

The European Union fiercely protects its domestic agricultural sector. When a product gets dumped into a category like 2106.90, it doesn’t just get hit with a standard ad valorem (percentage-based) tariff of 9%. It triggers the dreaded Agricultural Component (EA).

The EA is a punitive, specific duty calculated relentlessly based on the exact weight and percentage of sugar, starch, or milk fat in your product. Unlike standard tariffs, the EA isn’t capped by the value of the goods. In some cases, the agricultural duty can equal or even exceed the commercial value of the product itself.

For the importer, this wasn’t just a slight margin erosion. The sudden spike in the Cost of Goods Sold (COGS) destroyed the business model. Selling this natural colorant in the EU was now mathematically impossible. The Customs decision was a death sentence for the product line.

The Importer Who Refused to Yield
Faced with a ruling like this, 99% of importers would fold. They would accept the narrative of “you can’t fight city hall,” write off the sunk costs, and abandon the EU market. Or worse, they would quietly pay the ruinous taxes and bleed cash.

But this importer refused to play the victim.

They understood the fundamental truth of the product: “The sugar is merely a carrier, a stabilizer used for preservation and standardization. The core essence, the undisputed ‘star of the show,’ is the color!”

Armed with this conviction, they didn’t just write a polite letter of complaint; they launched a full-scale legal assault. To defeat Customs, they had to beat them at their own game. They dug deep into the archives of Dutch customs jurisprudence and pulled out a heavy weapon: ECLI:NL:GHAMS:2004:AO4626—a landmark judgment from the Court of Appeal in Amsterdam (Gerechtshof Amsterdam), dated February 19, 2004.

The Weapon: The 2004 Amsterdam Court of Appeal Precedent
To understand how the importer won, we have to look at what happened in that courtroom 16 years prior.

In the 2004 case, a different importer was fighting Netherlands Customs over a product called Beta-Carotene 30% Oil Suspension—an orange-red colorant used in butter, margarine, and juices.

This beta-carotene was produced through a highly complex, industrial biotechnological process. It involved placing a specific fungus (Blakeslea trispora) into massive industrial fermentation tanks filled with a nutrient medium consisting of sugar syrup, corn steep liquor, and soy oil.

Back then, Customs tried a similar trick. They argued that because the product was manufactured in an industrial bioreactor using a highly controlled medium (like sugar syrup) rather than being simply squeezed from a plant in nature, it was no longer a natural “vegetable colorant” (HS 3203 at 0% duty). Instead, Customs classified it as a “synthetic organic colorant” (HS 3204 at a 6.5% duty).

The Court of Appeal completely dismantled the Customs argument. The judges ruled that even though the manufacturing took place in an extensive industrial process, and even though complex mediums (like sugar syrup) were used to cultivate and extract it, the product fundamentally retained its vegetable origin and essential character as a natural colorant. The court explicitly stated that industrial processing and the presence of carrying mediums do not strip a product of its rightful place in HS 3203.

The Checkmate: Applying the Precedent
The 2019 importer took this 2004 judgment and used it as a legal battering ram against the 2106.90 (Food Preparation) classification.

Their argument to Customs was a masterpiece of legal logic:

“You are classifying our radish and safflower colorant as a ‘food product’ simply because it contains a high volume of sucrose syrup. But look at the 2004 Court of Appeal ruling! The highest judges already established that using sugar syrup as a medium or carrier in the manufacturing and stabilization process does NOT destroy a product’s essential character as a vegetable colorant (HS 3203). >
Our product is a colorant. The sugar is there for viscosity, preservation, and standardization—not to be eaten as a snack. Just as industrial fermentation didn’t turn beta-carotene into a synthetic chemical in 2004, the presence of stabilizing sugar syrup does not turn our colorant into a food preparation today. By law, it remains a vegetable colorant under HS 3203!”

The Smoking Gun: Tracing the DNA of the Fight
If you know where to look, the European customs databases hold the “smoking gun” that proves just how fiercely this battle was fought.

When we examine the original, devastating BTI issued in 2019 and compare it to the triumphant, revised BTI issued in 2020, we find two identical, irrefutable pieces of data embedded in the Dutch text:

aangevraagd onder kenmerk 2087432-01 (Applied under reference number: 2087432-01)

bekend onder laboratoriumnummer 2100 F 19 (Known under laboratory number: 2100 F 19)

These numbers are the administrative fingerprints of the case. The fact that the application number and the physical laboratory test number match perfectly across both documents proves a vital point: The importer did not cheat. They did not reformulate the product to have less sugar and submit a new sample. They forced Customs to look at the exact same product, from the exact same initial application, and legally compelled them to admit they were entirely wrong the first time.

The Great Reversal: 0% Duty and an Explosion in Profits
Checkmate. After a grueling standoff, the dam broke. In 2020, the Netherlands Customs officially invalidated their own 2019 decision, citing the 2004 jurisprudence as their new legal justification.

They issued a new BTI, formally reclassifying the red liquid not as a heavily taxed food preparation, but as what it always was: a pure “Coloring matter of vegetable origin” (HS 3203.00).
NLBTI2020-0103

The new duty rate? A definite, rock-solid 0%. The terrifying Agricultural Component (EA) vanished into thin air. In a single bureaucratic maneuver backed by ironclad legal precedent, a product that was on the verge of plunging the company into the red was resurrected into a high-margin powerhouse. Free from the shackles of agricultural taxes, the importer’s profit margins on this product line exploded overnight.

Conclusion: “The Authorities” Aren’t Always Right
This story serves as a stark, realistic warning for every supply chain manager, trade compliance officer, and executive operating in global trade: Never blindly accept a Customs decision just because it comes printed on official letterhead.

Customs authorities are prone to rigid, mechanical judgments. When they see the word “sugar” on an ingredient list, their algorithms and protocols will reflexively try to trap you in high-tax categories, ignoring the commercial reality of your goods.

It is your job to understand the true essence of your product, challenge the surface-level assumptions of the authorities, and fight back using hard evidence and historical legal precedent. In international business, your profit margins aren’t just protected by good sales strategies; they are defended by regulatory vigilance. Stand your ground, know the law, and don’t let the system classify your profits away.

Risks of using AI for HS classification

2026年4月1日 by TaichiKawazoe(河副 太智) Leave a Comment

As technology evolves, global cargo continues to increase in volume, speed, and complexity. How will HS classification be handled in such an era?

In the past, HS classification “artisans” meticulously classified each item one by one, relying on WCO (World Customs Organization) rules, their deep knowledge, experience, and seasoned intuition. However, in today’s world, where an overwhelming amount of cargo moves rapidly across the globe with ever-growing complexity, manual HS classification by humans is becoming increasingly difficult.

Consequently, many have turned to using AI for classification. Below are the results of a LinkedIn poll I conducted.

The following are the results of a poll conducted in 2023 titled, “How does your AI classifier perform?”

Linkedin2023

The following are the results of a poll conducted in 2025 titled, “How does your AI classifier perform?”

Linkedin2025

What was most surprising is that in a 2023 poll, 16% of people had a favorable opinion of AI’s judgment,
stating it had “more than 90% accuracy.”
However, this number decreased to 15% in 2025.

In just two years, AI as a whole has been evolving at a tremendous speed, and this remarkable development is astonishing to everyone.
However, AI classifiers seem to be an exception, as an interesting phenomenon is occurring where the number of people who rate them highly is inversely proportional to the development of AI.

Furthermore, HS classification is a challenging task that requires decisions as close to 100% accurate as possible, while also addressing the issue of differing opinions that vary by country and customs officer.

However, in the polls, 70% of respondents answered that the AI only provides ambiguous conclusions such as “some good, some bad” or “depends on the item category.”

Isn’t this a fatal flaw in the work of HS classification? Additionally, with 15% responding that it is “useless,” a total of 85% of people believe that the answers from AI classifiers are not perfect.

Next, I conducted a poll on LinkedIn titled, “Please tell me how you use AI in your HS classification process.” The results are as follows.

Linkedin Polls

📊 The data reveals that 77% of respondents are using AI for HS classification in some capacity.
(At the same time, I have the utmost respect for the 24% who continue to rely solely on their own deep knowledge and experience—true craftsmanship in our field.)

However, a very interesting “contradiction” emerges here.

In a previous poll asking about AI performance, the percentage of people who trusted AI’s judgment (stating it had “more than 90% accuracy”) actually dropped from 16% in 2023 to 15% in 2025.

In short:
📉 Trust in AI accuracy: Decreasing (2023 → 2025)
📈 AI usage rate: High at 77%

💡 The Reality on the Ground
“We don’t fully trust it, but we use it anyway.”
Isn’t this the current reality of HS classification?

As global trade volumes explode, the use of AI and technology is becoming indispensable.
However, even if an AI achieves 95% accuracy, the remaining 5% of misclassifications can jeopardize a company’s entire compliance standing.

This is exactly why the value of human expertise—understanding WCO Rules, GRI, and Rulings—is actually increasing in the age of AI.
We are the final line of defense.

AI is a powerful tool, but humans must remain at the wheel.

No matter how much technology evolves, the final decision-making must be done by human experts who cross-reference WCO rules and legal precedents.

The key to the future of HS classification lies in how effectively experts can collaborate with AI.

The real challenge, then, is determining how to effectively use AI to streamline the HS classification process. Those with only a superficial understanding of the subject tend to believe that “full automation via AI is possible,” but in reality, it is not that simple.

While it is true that AI can be helpful by providing correct HS codes for certain items, it frequently outputs incorrect codes the moment it encounters complex classification rules that it cannot fully grasp.

If a declarant submits a customs declaration without noticing these errors, they may suffer significant financial losses. Naturally, AI services always include disclaimers stating, “AI may make mistakes; please consult customs rulings for the correct HS code.”.

Therefore, when using AI for HS classification, it is impossible to even judge whether the AI’s answer is correct without a foundational knowledge of the classification rules.

Below are examples of why it is dangerous to let an AI perform HS classification when the user lacks the necessary knowledge.

CASTORS CASE

When classifying a standard caster with a ‘plastic wheel’ attached to a ‘steel mount,’ a quick keyword search for ‘caster’ will bring up its HS code directly. This might lead you to believe it’s an ‘easy item to classify.

At first glance, the classification seems straightforward because the product name “Casters” is linked to HS code 8302.20,
making it appear as though the task could be entirely outsourced to an AI.

However, there is a hidden pitfall here.

In the provisions of Note 2 to Chapter 83, there is a description written in small print that states the following:

Note 2 to Chapter 83

“Casters” classified under heading 83.02 are limited to those that meet either of the following conditions:

1.Those with a diameter (including tires) of 75 mm or less.

2.If the diameter exceeds 75 mm, the width of the wheel (including tires) must be less than 30 mm.

In other words, no matter how much the product in front of you functions or looks like a “caster,” and even if it is printed as a “caster” in the catalog, it will not be treated as a “caster of heading 83.02” under HS classification if it does not meet these dimensional specifications.

The moment it falls out of these requirements, you must restart the classification based on other criteria, such as the material (e.g., Chapter 39 if made of plastic, Chapter 73 if made of iron).

The cold hard fact shown by this example is that there is no value in simply “searching for a code based on a product name.”

True professional skill lies in “recognizing the moment you see the item name ‘caster’ that classification is impossible without data on the diameter and wheel width.”

The key is whether you can check with the shipper when you see an invoice or specification sheet lacking dimensional data, saying, “The information is insufficient. Please tell me the size.”

Beginners who do not know the regulations, or automation tools that make judgments based only on input text information, completely skip this process of “noticing missing information,” leading to incorrect declarations.

An Even Greater Barrier: Differing Interpretations of “Essential Character” Between Nations

If a product fails to meet the strict dimensional requirements mentioned earlier and is excluded from “Casters (8302),” the classification process becomes even more chaotic. What awaits next is the reality of “interpretational discrepancies between nations.”

For example, let’s consider the classification of a general-purpose wheel consisting of a “steel mounting fixture” and a “plastic wheel.” If it does not meet the requirements for a caster, the classification is determined by judging whether the “essential character” of the product is steel or plastic (General Rule 3(b)).

However, there is no absolute “correct answer” as to what constitutes the “essential character,” and opinions are completely split depending on the country.

Even for a “wheel” that appears extremely simple and straightforward, the correct answer changes the moment it crosses a national border.

  • Countries that classify it as Steel (7326): EU DEBTI40177/21-1 and Eurodocument, Turkey :TR160000210032,
    etc. (Emphasis on the mounting fixture)
  • Countries that classify it as Plastic (3926):
    USA : NY 859395,
    South Korea :품목분류3과-6422, etc.
    (Emphasis on the wheel)

PHOTOVOLTAIC CELLS CASE

PHOTOVOLTAIC CELLS is A panel that converts sunlight into electricity.

Hearing this function, both AI and beginners would likely attempt to classify it under heading 85.41 (Photovoltaic cells).

However, in the practice of HS classification, making a judgment based solely on the “primary function being the same” can cause fatal misdeclarations.

Let’s look at two cases (Photovoltaic cells cases) where items with nearly identical appearances and basic functions were classified under completely different HS codes.

■ Two “Photovoltaic Cells” That Are Alike Yet Different

Both of the following items are designed for the purpose of converting sunlight into electric power.

Item 1: Standard Photovoltaic Cells

Item 2: Photovoltaic Cells equipped with two USB charging ports

If you input “PHOTOVOLTAIC CELLS” into an AI or automated tool, it will likely return the same HS code. However, actual European Union Binding Tariff Information (BTI) clearly distinguishes them as follows:

Item 1 ➔ 8541.43 (Photovoltaic cells)
ITBTIIT922104-2022-BTI0264

Item 2 ➔ 8501.71 (Photovoltaic DC generator)
CZBTI48/149242/2023-580000-04/01

■ Why Does a Simple “USB Port” Change the Classification?

Item 1 is purely for “converting sunlight into electricity.”

On the other hand, Item 2 does not just convert energy into DC current; it also possesses the additional function of “directly supplying appropriate power to specific devices” through its USB ports.

The basis for this difference is clearly stated in the Explanatory Notes to the HS (EN to 8541 (B)(2)(i)):

EN to 8541 (B)(2)(i)

In other words, a solar panel that can “directly supply power” to devices such as smartphones via a USB port or similar interface is no longer a mere “solar cell (85.41),” but is classified as a “generator (85.01).

If you wonder why, it becomes a generator, it is because the ability to control and adapt the current for an external device transforms it from a simple energy harvester into an active power supply.

■ The Expert’s Perspective: Assessing “How the Energy Is Used”

AI tends to rely on superficial word associations like “PHOTOVOLTAIC CELLS = 8541.” However, a human expert observes the product’s “exit strategy” (interface)—how the generated energy is ultimately utilized—and verifies if it triggers the exclusion provisions in the Explanatory Notes (EN).

Even an element “as simple as a USB port,” as long as it serves the purpose of supplying power to specific equipment, changes the legal status of the item from a mere photovoltaic cell to a “generator.”

This case illustrates how dangerous it is to rely on the intuition that “similar products belong in the same category” or on the “probabilistic answers” generated by AI.

ARTIFICIAL FLOWERS CASE

When classifying “ARTIFICIAL FLOWERS,” it appears as though searching by the product name will yield an immediate answer.
If you let an AI or a similar tool handle the classification without careful thought, it will likely identify “ARTIFICIAL FLOWERS” under HS 6702 and conclude that this is a simple and correct solution.

However, there is a hidden pitfall here as well.
Consider two plastic artificial flowers that look and function identically. Despite their similarities, their HS classification can differ based on one factor: the “manufacturing process.”

If the flower is made by assembling individual petals and stems, it is classified as “Artificial Flowers (6702).”
However, if it is molded in one piece (integrated molding), it is excluded from that category by the legal notes (Chapter 67, Note 3(b)) and is classified instead as “Plastic Products (Chapter 39).”

CHAPTER 67, NOTE 3(B)

For an AI or a beginner who judges solely by “images” or “visual appearance,” the necessity of verifying the underlying manufacturing method would likely be completely unexpected.

HOURGLASS CASE

A typical hourglass is classified based on the material of its outer Vessel (e.g., 7013 for glass, 3926 for plastic).
An AI would likely learn this pattern—”hourglass = material of the Vessel”—very quickly.

The General Explanatory Notes to Chapter 91 also provide the following provisions:

General Explanatory Notes to Chapter 91

Therefore, as shown in the following EU BTI, an hour glass is generally classified under heading 3926 or 7013, depending on the material of the vessel.

However, what if we have a luxury hourglass where the “sand” inside is actually diamonds?

Based on overwhelming historical probability data, an AI is likely to conclude that “since it is an hourglass, it should be classified by the material of its vessel,” incorrectly applying General Interpretative Rule 3(b) and treating it as a product of glass or plastic.

However, a human expert stops right there. This is because they are aware of the existence of the following powerful provision in the legal notes of Chapter 71 (Note 1 to Chapter 71):

Note 1 to Chapter 71

According to this provision, if diamonds (precious stones) are used in even a part of the product, it must be classified preferentially under Chapter 71 (such as 7116.20), regardless of the material of the container.

The True Value of an Expert: The Ability to Notice “Legal Exceptions”

Because if AI continues to focus on “past correct answers (Hourglass = Vessel),” it would overlook these decisive Legal Notes. On the other hand, an expert does not simply look at “how it was classified in the past.” Instead, they follow the General Rules for the Interpretation of the Harmonized System (GRI 1) and constantly verify whether any exception provisions are triggered by cross-referencing the current Legal Notes.
In a U.S. Customs ruling (NY E89454), leading to its classification as “Articles of precious stones (7116).”

Tablet PC case

If it’s Windows or Android hardware with an Intel processor, camera, and touch panel, it should naturally fall under Heading 8471 (Automatic Data Processing Machines) of the Customs Tariff Schedule.
If you are convinced of that, you need to be aware of dangerous HS classification edge cases.


Surprisingly, the following three “genuine tablet PCs” were all excluded from 8471 and classified under Heading 8537 (Boards/Panels for Electric Control).

📱 Edge Case 1: Smart Home Control Hub (GB123085989)(invalidated)
Physically, it is a 7-inch Android tablet (built-in Wi-Fi, mic, camera). However, because the OS was customized (locked) to run a dedicated app for controlling home appliances and lighting—preventing the free use of other general-purpose apps—it was classified under 8537.

💻 Edge Case 2: Panel PC for Temperature Validation Systems (DE13327/15-1)(invalidated)
A 10.4-inch “Windows Tablet PC (1.5kg)” equipped with an Intel processor, Windows OS, and even a fingerprint reader. However, because it was imported as the primary dedicated control panel (interface) for a temperature management system, it was classified under 8537.

🖥 Edge Case 3: Dedicated Video Conferencing Controller (DEBTI40838/23-1)
A tablet enclosure with an 8-inch capacitive touchscreen and a stand. It was imported as a tabletop panel to control the video and communication of an entire conferencing system, and was likewise classified under 8537.

⚖️ Why is a “Tablet” not always an “ADP Machine”? (Legal Grounds)

The exclusion of these products from Heading 8471 typically stems from two critical legal hurdles in Chapter 84:

1. The “Freely Programmable” Requirement (Note 6(A)(ii)) Before looking at the function, a device must first meet the definition of an Automatic Data Processing (ADP) machine. Under Note 6(A)(ii), a machine must be “freely programmable” in accordance with the requirements of the user. If the OS is locked or the hardware is restricted to a specific application, it fails this primary test and is immediately disqualified from 8471.

Note 6(A)(ii) to Chapter 84

2. The “Specific Function” Rule (Note 6(E)) Even if a device is high-performance and technically capable of being programmed, Note 6(E) provides a powerful exclusion:

Note 6(E) to Chapter 84

In short, if the device’s essence is to perform a specific task—such as controlling a smart home, managing temperature, or presiding over a conference system—it is classified by that function (e.g., Heading 8537) rather than as a general-purpose PC.

In other words, no matter how high-performance the hardware (internal components) is, if it is combined with a “specific function (use)”—such as the electrical control of a smart home, temperature system, or conferencing system—and that function constitutes the essence of the product, Customs will not recognize it as a “general-purpose PC.”

🚨 Surge in Classification Errors and Penalty Risks in the IoT Era
Today, many home appliances and industrial machines are becoming IoT-enabled, with “tablet UIs” being integrated and imported as control panels.

The Pitfalls of AI in HS Classification

2026年2月17日 by TaichiKawazoe(河副 太智) Leave a Comment

Deterministic Law vs. Stochastic Probability

In the world of international trade, determining the correct HS (Harmonized System) code is often seen as a technical hurdle. However, beneath the surface, it is a rigorous legal exercise. As AI tools become more prevalent in customs offices, a dangerous gap is widening between how machines “think” and how the law actually operates.

The Deterministic Process of GIRs

Actual customs practice is a deterministic process governed by the General Interpretative Rules (GIRs). These six legal principles ensure that for any given product, there is only one legally correct classification.

The process must always begin with GIR 1, which states that classification is determined by the terms of the headings and any relative Section or Chapter Notes.

The Power of Legal Notes

The “Legal Notes” found at the beginning of HS Sections and Chapters are not merely suggestions—they are legally binding. They contain complex Exclusions and Priority Rules that can override physical appearance:

  • Exclusions: A product may look like a “plastic container,” but if a Chapter Note states, “This chapter does not cover specific containers for X,” it must be classified elsewhere, regardless of its material.
  • Priority Rules: Notes like Chapter 29, Note 3, dictate that if a product could fall under two headings, it must be classified in the heading that occurs last in numerical order.

The “Lack of Legal Reasoning” Trap in AI

Current AI models, specifically those using neural networks, struggle with the deductive logic required to navigate these rules. In a vector space where AI calculates “text similarity,” the phrases “Including A” and “Excluding A” are mathematically very close because they share almost all the same words.

However, in a legal context, those two phrases lead to diametrically opposed outcomes. While AI can learn the frequency of words, it cannot logically process a “Legal Exclusion” or a “Hierarchical Priority” based on the GIRs.

Comparison: Machine Learning vs. Legal Classification

Feature ML-Based AI Tools (Stochastic) Legal HS Classification (Deterministic)
Foundation of Inference Statistical patterns and text similarity in datasets. GIRs and Section/Chapter Legal Notes.
Nature of Output Probabilistic guess (e.g., “95% certain”). The single legally correct answer (100% binding).
Handling Exceptions Weak at “edge cases” or complex exclusions not frequent in data. Mandatory application of strict exclusionary rules.
Process Transparency Black Box: Difficult to verbalize the legal rationale. Transparent: Can cite the exact GIR or Note used for the decision.

The Danger of Overconfidence: The “Confidence Level” Illusion

One of the most significant risks highlighted in WCO (World Customs Organization) reports is the misunderstanding of “Confidence Levels.”

A machine learning model might assign a 95.76% confidence score to a classification that is legally incorrect. For example, errors have been reported in the classification of automotive engine mounts where AI provided high confidence for the wrong code.

Crucial Distinction: This percentage does not mean there is a 95% chance the code is legally correct. It simply means the code aligns closely with the AI’s internal statistical patterns.

When importers or brokers see a high percentage, they often mistake it for a legal guarantee. This leads to “automation bias,” where users stop questioning the output, eventually leading to misdeclaration, fines, and compliance audits.

“AI HS classifiers” cannot completely replace “Human expert classifiers”

2025年10月17日 by TaichiKawazoe(河副 太智) Leave a Comment

A surprising result emerged when we solicited opinions from many people who have used AI classifiers.

What was most surprising is that in a 2023 poll, 16% of people had a favorable opinion of AI’s judgment, stating it had “more than 90% accuracy.”

However, this number decreased to 15% in 2025.

In just two years, AI as a whole has been evolving at a tremendous speed, and this remarkable development is astonishing to everyone.
However, AI classifiers seem to be an exception, as an interesting phenomenon is occurring where the number of people who rate them highly is inversely proportional to the development of AI.

Furthermore, HS classification is a challenging task that requires decisions as close to 100% accurate as possible, while also addressing the issue of differing opinions that vary by country and customs officer.

However, in the polls, 70% of respondents answered that the AI only provides ambiguous conclusions such as “some good, some bad” or “depends on the item category.”

Isn’t this a fatal flaw in the work of HS classification? Additionally, with 15% responding that it is “useless,” a total of 85% of people believe that the answers from AI classifiers are not perfect.

From this, we can understand the following two points:

1.
I do not intend to completely negate AI classifiers, because they may have excellent aspects as a co-pilot. However, at present, they can only serve in a supplementary role. It is a terribly dangerous act to declare the decisions of an AI classifier to customs without any knowledge or questioning of the output.

2.
HS classification by human experts is an essential skill, knowledge, and experience that will continue to be needed for a long time to come.
No matter how much AI evolves in the future, the final judgment by expert personnel is essential.

Rather than viewing AI with anxiety about white-collar jobs being replaced, we urge professionals to recognize the enduring value of their role in HS classification.

Your expertise is more crucial than ever and will continue to be in high demand.

Continue to fulfill your duties with pride, knowing you are an essential expert in the future of the trade industry.

When a ‘Part’ Isn’t a ‘Part’: A Company’s $11 Million Fight Against HS Misclassification

2025年9月8日 by TaichiKawazoe(河副 太智) Leave a Comment

Prologue: The Nightmare Begins

On December 18, 2018, a notice arrived at the headquarters of M/s Secure Meters Ltd., a leading smart meter manufacturer in India. The sender was the Directorate of Revenue Intelligence (DRI), the investigative arm of India’s Ministry of Finance. The contents were difficult to believe.

“There is an error in the tariff classification of the electronic components you have imported. You are ordered to pay a supplementary duty of ₹458,388,872 (approx. $5.5 million USD) and a penalty of the same amount.”

The total demand was nearly $11 million. It was a nightmarish proclamation that threatened the very existence of the company.

The root of it all was a single difference of opinion over the interpretation of the HS code for a tiny electronic component, small enough to fit on a fingertip: the “communication module.” And this was despite the fact that Secure Meters had been importing this component since 2017, had sincerely explained their reasoning when questioned by a customs officer at the time, and had their classification accepted.

This is the record of a dramatic legal battle where the fate of a company and the principles of justice in international trade were put to the test.

Chapter 1: The Castle of the Future and a Single Lego Block

The stage for this story is the “smart meter,” an indispensable piece of modern infrastructure.

If the old electricity meters were like a “film camera” that only a meter reader could check once a month, the smart meter is a “modern smartphone.”

It measures electricity consumption every 30 minutes and automatically transmits the data to the power company. It is the completed “castle” that supports the future of our power grid.

So, what was the “communication module” that became the flashpoint for a $11 million dispute?

It is the heart that supports the “intelligence” of the smart meter. It’s an electronic circuit board equivalent to the “SIM card” or “Wi-Fi chip” in a smartphone. Without it, a smart meter is just a box that displays numbers.

What Secure Meters imported was not the finished smart meter (the castle).

It was just a single component for building the castle: a “Lego block.”

Chapter 2: The Two Numbers That Decided a Fate – The Courtroom Showdown

In court, the arguments of the two sides were in direct opposition. The core of the dispute is summarized in the table below:

Point of ContentionArgument of Customs (Prosecution)Argument of Secure Meters (Defense)
Claim“This component’s only destiny is to be part of a meter. Therefore, it is a ‘child part’ of the meter.”“The law requires that goods be classified ‘as they are’ at the moment of importation.”
HS Code9028 (Parts for electricity meters, etc.)8517 (Parts for telecommunication apparatus)
Tariff Rate20%0% (Eligible for exemption notification)
ResultBack-duties and penalty of approx. $5.5 million eachNo additional duty payable

The first-instance judgment (Order-in-Original) issued by the Principal Commissioner fully supported the customs’ claim. Secure Meters was pushed into a desperate corner.

Chapter 3: The Gavel of Justice and the “Lego Block Principle”

The stage moved to the appellate court, the Customs, Excise & Service Tax Appellate Tribunal. The verdict handed down was a complete victory for Secure Meters.

Underpinning the decision was an absolute rule in import classification, a legal basis we should call the “Lego Block Principle.”

Legal Basis 1: The Ironclad Rule of Customs Law – The “Lego Block Principle”

The tribunal declared unequivocally:

“Customs duty must be determined by the form of the goods as they cross the border. What the goods may become after they enter the country is irrelevant.”

This is the very essence of the Lego analogy.

If you import a single red Lego block, it is classified as a “toy block.” Even if you plan to use that block later to build a giant castle, you did not import a “castle.”

Secure Meters had imported a “communication module (the Lego block),” not a “smart meter (the castle).” This simple, undeniable fact defeated the $11 million claim.








Legal Basis 2: The Court’s Scathing Rebuke

However, this trial did not end with a simple victory.

The tribunal directed unusually harsh words at the investigation methods of the customs authorities.

In fact, Secure Meters had been importing this component since 2017.

When initially questioned by a customs officer about the classification, the company had sincerely explained its reasoning, and the classification had been accepted at the time.

Based on this fact, the tribunal severely criticized the DRI’s heavy-handed investigation, stating that for a different investigative body to later claim the importer had intentionally evaded taxes was “simply outrageous.”

This was a critically important judgment that protected the predictability and rights of importers.

Final Chapter: The Only Shield to Avoid the Nightmare – The Lesson from This Victory

The Secure Meters case offers an extremely important lesson in the world of HS code classification. It is the terror of how the single question of whether a product is considered a “part” or an “independent article” can become the source of immense business risk.

For instance, recall the case of Toyota in Thailand. In that instance, finished vehicles were intentionally disassembled and declared as “parts” upon importation to benefit from lower tariff rates. However, Thai Customs deemed this a circumvention of the law and applied the high tariff rate applicable to complete vehicles. That was a case of a finished product being misrepresented as parts.
https://tariffengineering.com/272-11million-dollar-loss-due-to-inadequate-hs-classification/

This case presents the complete opposite scenario. A legitimate, independent article (a component for telecommunication) was unilaterally classified by the customs authorities based on its future use as a “part of a meter.” What the court defended was the fundamental principle of customs classification: to classify goods in their condition as imported.

The stance of Secure Meters in fighting back against this unreasonable demand under the full force of the law is commendable. However, the most crucial lesson we must learn from this incident is “risk prevention.”

In transactions involving high-value duties, a verbal confirmation is virtually powerless. The most reliable defense for an importer is to apply for an “Advance Ruling” and obtain a legally binding, official opinion in writing from the customs authorities. Securing a definitive HS code in advance is the only, and absolute, shield to protect a company from a “customs nightmare” such as this.

$272.11MILLION DOLLAR LOSS due to inadequate HS classification

2025年9月3日 by TaichiKawazoe(河副 太智) Leave a Comment

The worst scenario of inadequate HS classification from a judicial example.
With this real example, you can see how HS misclassification is horrible and could lead to MULTI-MILLION DOLLAR LOSS.

The fact is that Thailand Supreme Court ordered the Japanese top car maker “Toyota” to pay $272.11 million due to the inadequate HS classification.

Source: Reuters

In the beginning, TOYOTA intended to export Automobiles to Thailand.
In this case, the tariff rate for Automobiles(HS:8703.23) is 80%(see the image)

The duty rate of 80% is very high and there is no FTA preferential treatment between Thailand and Japan for Automobiles(HS:8703.23).

On the other hand, FTA between Thailand and Japan, there is preferential treatment for “Automobile parts” (HS:8708) 60% to 30%.

Toyota came up with an idea that they disassemble the Automobiles, ship them to Thailand and declare them as “Automobile parts”, and after clearance, they reassemble them to complete the car in Thailand.

If Toyota had exported Automobiles to Thailand, the duty rate would be 80% but if they disassemble them into Automobile parts, the duty rate would be 30%, literally, they succeeded to reduce 50% of customs duty.

It seemed it works, so they continued this Tariff Engineering from 2010 to 2012 for more than 20,000 vehicles assembled at Toyota’s Gateway factory.

But this is a double-edged strategy.

After that, Thailand customs pointed out that they are not Automobile parts because after importing those items to Thailand, they can be reassembled to be a complete automobile.

It’s nothing other than “Completely Knocked Down”, Thailand customs thought.

To understand why Automobile parts are regarded as complete automobiles by customs, we need to refer to the “General Rules of Interpretation (GRIs)”

GRI 2(a) states below

2. (a) Any reference in a heading to an article shall be taken to include a reference to that article incomplete or unfinished, provided that, as presented, the incomplete or unfinished article has the essential character of the complete or finished article.

It shall also be taken to include a reference to that article complete or finished (or falling to be classified as complete or finished by virtue of this Rule), presented unassembled or disassembled.

It means an unassembled or disassembled product is regarded as a completed product.

That’s the reason why Automobile parts are regarded as complete automobiles by Thailand customs.

The argument between Thailand customs and Toyota had taken a long time and it was brought to Court.

Sept 15, 2022 – Thailand Supreme Court on Thursday upheld a lower court ruling that the local unit of Toyota Motor Corp owed the government 10 billion baht ($272.11 million) in extra taxes for importing components not subject to a reduced tariff.

Here is The link to Thailand Supreme Court judgment

Below is translated judgment.
(Sorry it’s hard to read due to machine translation.)

Today at 11:00 a.m., the Supreme Court of Justice Department of Tax Cases read the verdict.
The Supreme Court means transmitting images and sounds via electronic media to the Central Tax Court.

Cases between Toyota Motor Thailand Company Limited, the plaintiff, the Customs Department, the 1st defendant, and the Revenue Department
The 2nd defendant, a total of 10 cases, accounted for total assets of 10 million baht, In all ten cases, plaintiffs sued that between 2010 and 2012, the plaintiff imported the friend’s car parts used to produce Toyota Prius models by the notification of the Ministry of Finance Regarding the reduction of duty rates and the exemption of customs duties under Section 12 and Section 14 of the Royal Decree on Customs Tariffs B.E. between the Kingdom of Thailand and Japan For the Economic Partnership (JTEPA), the plaintiff asked.

revoke the assessment of the assessment and make an appeal decision of the Appeal Committee.

Both defendants testified that the assessment and The appeal ruling are lawful.

Central Tax Court adjudged to revoke the assessment and Appeal Court of Appeal The special judges returned.

to dismiss the plaintiff’s petition with permission from the Supreme Court
The Supreme Court’s Tax Litigation Division found that the plaintiff’s car parts are to be imported when assembled having a material nature It is important for the Toyota Prius model and can be assembled into Toyota cars.

Prius immediately, so it must be classified into the coordinate type of the complete part or for the successfully imported either disassembled or not assembled as a complete set of parts.

Tariff 8703.23.41 or 8703.23.51(according to the time of import) according to the tariff interpretation rules
Customs Clause 1, *Article 2 (a)  and Article 6 in Part 1 annexed to the Royal Decree on Customs Tariffs, B.E. 2530 (1987)

*Guess it means GRI 2(a)

Therefore, it is not exempt from duty and reduces the duty rate according to the notification of the Ministry of Finance issued to comply with
the JTEPA agreement and is not entitled to exemption from duty according to the Ministry of Finance’s notification regarding the reduction of duty rates and exemption of customs duties under Section 12 of the Royal Decree on Customs Tariffs, B.E. 2530
(No. 18) dated October 13, 2010, neither has the right to reduce the duty rate at the import duty rate of 30 percent.

under the Notification of the Ministry of Finance Re: Reduction of Duty Rates and Exemption of Customs Duty under Section 12
of the Royal Decree on Customs Tariffs, B.E. in the appellate decision to charge the rate 80% of the import duty was approved, while other issues were not accepted by the court, and the verdict was confirmed.

Sometimes I hear that “to reduce duty rate, disassemble the commodity into parts to import and reassemble them in the targeting country, Wow this is a smart way of Tariff Engineering”

But this is the inadequate solution for reducing the duty rate that most people easily come up with.

In short term, it might work I admit, but customs officers are not foolish in overlooking this behavior. Therefore it turned out to be a nightmare one day.

It does not mean disassembling the commodity into parts to import is not a bad way. Sometimes depending on the commodity, disassembling is required.

But please keep in mind that customs seek the possibility to adopt GRI 2(a) to disassembled commodity to reclassify to another HS code.
Don’t underestimate GRI 2(a), it is very important.

If there is a need for disassembling commodities, I recommend consulting customs that the HS code is appropriate in a wide range of views.

As a Japanese, I am personally proud of Toyota’s international business.
Hoping Toyota overcomes this incident and develops more.
This incident must be a great guideline for many traders worldwide.
