Six situations where a wrong HS code costs more than the review

HS code errors are rarely discovered until a shipment hits customs. By then, the cost of correction is significantly higher than the cost of getting it right upfront.

You are importing or exporting a product for the first time

The HS code determines the duty rate, applicable restrictions, and any licensing or permit requirements. Getting it right before your first shipment avoids delays, overpayment, and compliance risk from day one.

Your shipment has been held or queried at customs

Customs authorities have flagged your classification. A written rationale memo with the correct code and the regulatory basis for that classification is often what resolves a customs query fastest.

You want to verify an existing classification

Your freight forwarder or broker assigned a code. You want to confirm it is correct before it becomes the code of record for a high-volume product where a reclassification would trigger back-duty liability.

Your product is borderline between two classifications

Some products sit between two HS headings with different duty rates. A written rationale memo from a compliance specialist establishes a defensible position and protects you if the classification is challenged.

You are entering a new market with different tariff schedules

The same product can attract very different duty rates in different markets. An EU TARIC code and a US HTS code for the same product may differ. TGC reviews the applicable schedule for your specific destination.

You are exporting a product and also need an ECCN assessment

Certain products are subject to export controls under US EAR or EU dual-use regulations. An ECCN assessment is separate from the HS code review but can be included as an add-on. TGC can identify the applicable ECCN and provide a brief analysis of why it applies - a detailed licensing assessment would be scoped separately.

What we review

Four areas assessed in every HS code review

Every HS code review covers classification, duty exposure, and risk flags. ECCN export control screening is available as an add-on. Not just a code - a complete tariff picture.

HS, HTS and TARIC classification

The correct 6-digit international HS code, plus the market-specific extension where applicable - US HTS code to 10 digits, EU TARIC code to 10 digits, or the schedule relevant to your target market.

  • 6-digit HS code confirmed
  • HTS code (US) where applicable
  • TARIC code (EU) where applicable
  • Borderline product analysis where relevant

Duty and VAT exposure analysis

The applicable tariff rate at the confirmed classification, including any preferential rates under free trade agreements, anti-dumping duties, or safeguard measures that may apply to your product.

  • MFN duty rate at confirmed code
  • Preferential rates under applicable FTAs
  • Anti-dumping or safeguard duty flags
  • VAT and import tax implications

ECCN export control screening (add-on)

Available as an add-on to your HS code review. TGC identifies the applicable ECCN under US EAR and provides a brief analysis of why it applies. Detailed licensing assessment is scoped separately.

  • ECCN determination under US EAR
  • Brief rationale for applicable classification
  • EU dual-use screening where relevant
  • Pricing varies based on product complexity

Risk flags and advisory

Restricted or prohibited goods flags arising from the confirmed classification, plus guidance on whether a Binding Tariff Information ruling is advisable for your product.

  • Restricted or prohibited goods flags
  • BTI ruling recommendation
  • Country-specific classification notes
What you receive

What you receive - a defensible classification memo, not just a code.

Automated classification tools give you a number. TGC gives you a written rationale you can present to a customs authority, a freight forwarder, or a regulatory auditor.

Classification

Confirmed HS code with written rationale

The confirmed code and the reasoning behind it.

The confirmed HS code for your product, plus - critically - a written rationale memo explaining the classification reasoning with reference to the applicable chapter notes, explanatory notes, and general rules of interpretation. This is what distinguishes a defensible classification from a guess.

Confirmed 6-digit HS code
HTS or TARIC extension where applicable
Written rationale citing chapter notes and GRIs
Borderline analysis documented where relevant
Financial

Duty and VAT exposure at confirmed rate

Know the full landed cost picture before you commit.

The applicable tariff rate at the confirmed classification, including MFN rate, any preferential rates under relevant free trade agreements, and any anti-dumping or safeguard measures. The VAT and import tax implications are included so you have the complete landed cost picture before committing to pricing or distribution agreements.

ECCN screening (add-on)

Available where export control classification is also required.

Where ECCN screening is requested as an add-on, TGC identifies the applicable Export Control Classification Number under the US Export Administration Regulations and provides a brief analysis of why it applies. Where the product is a clear EAR99, this is straightforward. A detailed licensing assessment - covering what licences are required, how to obtain them, and destination or end-user screening - is a deeper exercise scoped separately. EU dual-use screening is included where relevant.

Brief rationale for applicable classification
EU dual-use screening where relevant
Detailed licensing assessment available separately
Risk

Risk flags and BTI advisory

Licensing, restrictions, and BTI guidance upfront.

Where the product is borderline or high-value, TGC advises on whether a Binding Tariff Information ruling from the relevant customs authority should be sought to lock in the classification permanently. Restricted or prohibited goods flags are identified where they arise from the confirmed classification.

Example output
Product category Wireless audio device
Target market European Union
Applicable schedule EU Combined Nomenclature (TARIC)
Review outcome Classification confirmed
Confirmed HS code
8518.30 - Headphones and earphones, whether or not combined with a microphone, and sets consisting of a microphone and one or more loudspeakers
TARIC code (EU)
8518.30.95 00 - Other (wireless headphones/earphones, not combined with microphone, for use with mobile telephones)
Written rationale
Product classified under Chapter 85 (Electrical machinery and equipment) on the basis that it is a sound-reproducing apparatus operating wirelessly via Bluetooth. The product falls within heading 8518 per Note 3 to Chapter 85 and the Explanatory Note to heading 8518, which includes headphones and earphones whether or not combined with a microphone. Classification at subheading 8518.30 is confirmed. The product is not excluded by any chapter note.
Duty exposure (EU)
MFN rate: 0% under TARIC 8518.30.95 00. No anti-dumping duties currently applicable to this product from the declared country of origin. EU-UK Trade and Cooperation Agreement (TCA) preferential rate: 0% subject to Rules of Origin compliance. Import VAT applicable at destination member state standard rate.
ECCN screening
Product assessed as EAR99 under US Export Administration Regulations. No specific ECCN applies. Export from the US to most destinations does not require a licence under EAR. No EU dual-use classification applicable. Note: standard export controls (OFAC, SDN list screening) apply regardless of EAR99 classification.
Risk flags
No import licence or permit required for this product category in the EU. Product is not on any restricted or prohibited goods list. Radio equipment subject to RED Directive (2014/53/EU) requirements for market access - CE marking and technical documentation required. This is a regulatory requirement, not a customs restriction.
BTI advisory
A Binding Tariff Information ruling is not recommended for this product. The classification is unambiguous and the duty rate is 0%, limiting the financial benefit of a BTI. A BTI would be advisable only if the origin-specific duty rate or Rules of Origin compliance were in question.

Classification confirmed at 8518.30.95 00. Duty rate 0% MFN. Product is EAR99. RED Directive compliance required for EU market access - this is a product compliance obligation, not a customs issue. No BTI recommended at this time. Full written rationale available for customs authority presentation.

The cost of getting it wrong

What a wrong HS code costs when customs finds it

A wrong HS code is rarely a one-time problem. It compounds across every shipment until it is found - usually by a customs authority.

HS code review From $40 Written rationale included
Back-duty liability Potentially unlimited Across all historical shipments
Customs hold costs $500 - $5,000+ per hold Storage, delays, reclassification
Get your HS code reviewed from $40 →

Customs hold and delayed clearance

A misclassified product can be held at the border pending reclassification. Every day in storage adds to your landed cost, and time-sensitive shipments miss their windows.

Back-duty liability and penalties

If customs reclassifies your product to a higher duty rate, you become liable for the duty underpayment on every historical shipment under that code - plus interest and penalties. This liability can span years.

Duty overpayment on compliant shipments

Misclassification can go the other way - overpaying duty at a higher rate when the correct code attracts a lower rate. Reclaiming overpaid duty is possible but administratively complex.

Export control violations

Exporting a product subject to EAR or dual-use controls without the correct ECCN and licence is a serious regulatory offence with significant financial and reputational consequences.

Pricing and margin errors

If your landed cost model was built on an incorrect duty rate, your margin calculations are wrong. Contracts, distribution agreements, and pricing to retailers may all be based on a cost structure that does not reflect reality.

FTA benefits lost or clawed back

If you claimed preferential duty rates under a free trade agreement using an incorrect code, customs can claw back the difference between the preferential and MFN rates across all prior shipments.

Client outcome

What clients say

"Our freight forwarder had been using the same HS code for three years. TGC's review identified that we had been overpaying duty at a rate of 6.5% when the correct classification attracted 0% under our FTA. The written rationale memo gave us everything we needed to submit a duty reclaim and correct the classification going forward."

Common questions

FAQ - HS code review service

An HS code review is an expert assessment of your product's tariff classification under the Harmonized System. TGC verifies or assigns the correct HS code, provides a written rationale memo explaining the classification reasoning with reference to the applicable chapter notes, and identifies your duty and VAT exposure at that classification. You receive a document you can present to a customs authority - not just a code.
The first 6 digits of an HS code are universal - they are the international standard maintained by the World Customs Organisation and form the basis for tariff schedules in every country. The remaining digits are country-specific: every country or customs territory extends the 6-digit HS into its own national tariff schedule. The HTS (US) and TARIC (EU) are the most commonly referenced, but the same principle applies worldwide. TGC reviews the applicable national schedule for your specific target market.
Online lookup tools and AI classifiers produce a code. TGC produces a well-reasoned classification with a written rationale citing the applicable chapter notes and General Rules of Interpretation - documentation you can use to support your position with a customs authority or freight forwarder. That said, TGC's classification is our expert opinion based on the information provided; it is not a binding customs ruling. Customs authorities are not legally bound to accept it. The only classification that binds customs is a Binding Tariff Information (BTI) ruling formally applied for prior to shipment - TGC advises on whether a BTI is appropriate as part of your review. For complex products, borderline classifications, or high-value shipments, automated tools carry significant risk - the liability for a wrong classification sits with the importer or exporter, not the tool.
A Binding Tariff Information ruling is an official decision from a customs authority that legally binds them to accept a specific classification for your product for a defined period (typically 3-5 years in the EU). It provides absolute certainty and is portable - you can present it at any EU customs office. TGC advises on whether a BTI is appropriate for your product as part of the review. Not all products require a BTI - we only recommend one where the product is genuinely borderline or where the commercial value of certainty justifies the cost of obtaining it.
Yes. TGC can review the applicable tariff classification for multiple markets in a single engagement - EU TARIC, US HTS, UK Tariff, and other market-specific schedules. Each market receives its own classification confirmation and duty exposure analysis. ECCN screening can be added where required. Contact us to discuss multi-market pricing.
