How to Recover Refunds from HTS Misclassification

Understanding HTS Misclassification

The Harmonized Tariff Schedule of the United States (HTSUS) contains approximately 17,000 tariff classification codes. Assigning the correct code to imported merchandise is both an art and a science — and mistakes are extraordinarily common.

HTS misclassification occurs when an imported product is assigned a tariff code that does not accurately describe the merchandise under the legal framework of the HTSUS General Rules of Interpretation (GRIs). The consequences can be severe: duty rates can vary from 0% to 37.5% depending on classification, and Section 301 China tariffs are layered on top for Chinese-origin goods.

Common Sources of Misclassification

1. Classification by commercial description vs. legal description

Many importers (and some brokers) classify goods based on how they're described in commercial catalogs or invoices, rather than by applying the GRIs. This frequently leads to error.

2. Multi-component and composite goods

Products that combine multiple components require careful analysis under GRI 3 to determine the "essential character" of the item. This is a frequent source of disputes.

3. Rapid product evolution

Technology products especially tend to evolve faster than tariff schedules. A product that was correctly classified in 2020 may need reclassification after significant design changes.

4. Over-reliance on broker classification

Customs brokers are not liable for misclassification unless they have reason to know the classification is wrong. Importers remain the responsible party.

Identifying Misclassification Opportunities

Signs that your HTS classifications may be incorrect:

Recovery Mechanisms

CBP Protests (most common)

For liquidated entries within the 90-day protest window, a formal protest under 19 U.S.C. § 1514 is the primary recovery mechanism. Our attorneys prepare detailed legal memoranda arguing for the correct classification and requesting a refund of overpaid duties.

Post-Summary Corrections (PSCs)

For entries that have not yet been liquidated, PSCs filed through ACE can correct misclassifications before final duty assessment. This is the fastest and least expensive recovery path.

Duty Drawback

If misclassified goods were subsequently exported, drawback may be available on duties already paid — even beyond the protest window.

CIT Litigation

For denied protests involving significant sums or important legal questions, appeal to the Court of International Trade offers another avenue. CIT decisions set binding precedent for future classifications.

The Classification Analysis Process

Our attorneys conduct the following analysis for each product:

1. Review physical characteristics, composition, and function

2. Apply the six GRIs in sequence

3. Research applicable CBP rulings (searchable at CBP's CROSS database)

4. Review relevant CIT and CAFC decisions

5. Draft a classification memorandum supporting the correct HTS number

6. Calculate the refund potential based on corrected duty rate applied to historical entries
