HTS Classification Review Checklist

Importers

HTS misclassification creates compounding compliance risk: back duty assessments on all entries filed under the wrong code, AD/CVD exposure, Section 301 tariff liability, and CBP audit vulnerability. Classification errors are rarely isolated — CBP audits all entries filed under the same code within the recordkeeping period, not just the shipment where an error was initially found. This checklist covers the methodology, verification tools, trade remedy exposure checks, and recordkeeping practices that reduce classification risk before CBP identifies it first.

Starting the Classification — GRI Methodology

  • Identify the article's essential character and primary function before selecting any heading
  • Review Section Notes and Chapter Notes first — exclusions and inclusions at this level control classification before any heading text is applied
  • Apply GRI 1 through GRI 6 in sequence — do not skip ahead or classify by product name, keyword search, or supplier description
  • Determine whether the article is complete, unfinished, unassembled, or a set — each condition triggers different GRI rules and can change the heading

Code Verification

  • Use USITC HTS Online (hts.usitc.gov) for the official 10-digit U.S. HTS code — do not rely solely on supplier HS codes or internal databases without cross-referencing against the official tariff schedule
  • Confirm the full 10-digit U.S. code — not just the 6-digit international HS subheading; U.S.-specific notes add further specificity at the 8- and 10-digit levels
  • Search CBP's CROSS ruling database (rulings.cbp.gov) for any binding or informational rulings on similar articles from the same or related HTS heading
  • Verify the general rate of duty and any applicable trade agreement preferential rates — USMCA, CAFTA-DR, GSP, or other applicable preference programs

Trade Remedy and Special Tariff Exposure

  • Section 301 tariffs: confirm whether the HTS subheading falls under List 1, 2, 3, or 4A/4B for goods of Chinese origin — origin determines exposure, not country of shipment
  • Section 232 tariffs: confirm whether the product is steel or aluminum subject to tariffs under the applicable Presidential Proclamation
  • IEEPA tariffs: review current CBP Federal Register guidance for applicable HTS chapters — check for any active modifications, exclusions, or pauses
  • AD/CVD orders: check the USITC and CBP's ADCVD portal for any active antidumping or countervailing duty orders applicable to your HTS subheading and country of origin
  • Confirm country of origin for each applicable trade remedy — exposure depends on actual origin, not the declared origin on a commercial invoice or supplier's certificate

Country of Origin Verification

  • Confirm origin based on the substantial transformation test — the country where the article received its name, character, and use through manufacture or processing
  • Origin is not determined by country of last shipment, country of final packaging, or the country named on a supplier's invoice without independent verification
  • If claiming trade agreement preference (USMCA, CAFTA-DR, or other): confirm the applicable tariff shift rule or regional value content threshold is met and retain supporting documentation
  • If product is manufactured in China: confirm Section 301 tariff exposure applies even if the shipment routes through a third country before U.S. arrival

Classification Records and Review Cadence

  • Document the GRI analysis and heading selection rationale for each product in your classification library or import compliance file
  • Retain country of origin determination records and supporting evidence for the CBP 5-year recordkeeping period under 19 CFR 163.4
  • Review all active HTS codes each January 1 — the U.S. Harmonized Tariff Schedule is updated annually and heading descriptions, rates, or statistical suffixes can change
  • Consider a CBP binding ruling (CBP Form 177) for high-value, high-volume, or frequently questioned classifications — a binding ruling provides certainty and audit protection
  • Flag any HTS subheading where a CBP penalty has been issued in the same industry or commodity — this signals a classification pattern CBP is actively reviewing
