What is HTS Code?

Harmonized Tariff Schedule code — the 10-digit number that determines the duty rate on imported goods in the U.S. In the context of U.S. customs and tariff recovery, understanding hts code is essential for navigating the CAPE refund process and ensuring accurate duty assessment.

Definition

The Harmonized Tariff Schedule (HTS) code is the 10-digit number that determines the duty rate on imported goods in the United States. Managed by the U.S. International Trade Commission (USITC), the HTS contains over 17,000 distinct classification codes organized into 99 chapters. The first 6 digits follow the international Harmonized System (HS). Digits 7-8 are U.S.-specific subdivisions. Digits 9-10 are statistical reporting suffixes. The HTS code determines: the base duty rate (MFN), eligibility for preferential programs (GSP, USMCA), and applicability of special tariffs (Section 201, 232, 301, IEEPA). Per CBP ruling HQ H350722, AI platforms may classify at the 6-digit HS level, but the full 10-digit determination is the licensed broker's responsibility.

How HTS Code Relates to Tariff Refunds

The HTS code is central to CAPE refund eligibility. Each entry on your ES-003 has an HTS code that determines whether it is subject to IEEPA or Section 301 tariffs. Tariffi's analysis maps HTS codes to active tariff programs to identify qualifying entries. Misclassified entries — those with incorrect HTS codes — may need correction to ensure the correct refund amount.

Example

HTS code 9503.00.0073 (toy construction sets from China) carries a 0% base rate plus a 25% Section 301 tariff. When the Section 301 rate drops to 7.5%, the 17.5% difference is the refundable overpayment per entry, calculated on the customs value.

Frequently Asked Questions

Where can I look up HTS codes?
The official HTS is published by the USITC at hts.usitc.gov. CBP's CROSS database (rulings.cbp.gov) also provides rulings that clarify HTS classification for specific products.
Can I use AI to classify my HTS codes?
Per CBP Ruling HQ H350722, AI platforms may classify at the 6-digit HS heading level. The full 10-digit U.S. HTS statistical suffix must be determined by a licensed customs broker.
How often do HTS codes change?
The HS is revised every 5 years by the WCO. The USITC updates the U.S. HTS more frequently to reflect new trade actions, exclusions, and statistical subdivisions.
