Base HTS Duty
The ordinary HTS duty rate for the product classification applies first. This is product-specific and ranges from 0% to 35%+ depending on the tariff line.
Current U.S. Section 301 additional tariffs on China-origin goods — operative lists, Chapter 99 headings, rates, effective dates, and exclusion counts — all sourced from official USTR and USITC HTS data.

The ordinary HTS duty rate for the product classification applies first. This is product-specific and ranges from 0% to 35%+ depending on the tariff line.
The legacy China lists add their dataset-recorded `rateExpression` on top of the base rate, applied via the Chapter 99 headings shown in the table below (9903.88.01, 9903.88.02, 9903.88.03, etc.). Status and scope come directly from the canonical tracker dataset.
The Further Reciprocal (FYR) escalation headings add their recorded `rateExpression` on specific product scopes. Each FYR measure is shown in the FYR escalation table below; verify scope and effective dates with USITC HTS and the applicable Federal Register notice.
No forced-labor Section 301 measure is recorded in the loaded dataset. The measure applies in addition to all other layers and is subject to specific exemption headings, which are listed in the dataset.
0 product exclusions are currently operative in the dataset. Scope and effective ranges are listed in the table below. Verify exclusion scope against the full U.S. note text on USITC HTS.
Section 301 additional tariffs are additive to base HTS duty. The total additional duty is the sum of the applicable legacy list, FYR, and forced-labor rates shown in the dataset — each recorded as `rateExpression`. Use the Import Duty Calculator to estimate total landed cost for a specific product and origin.

The dataset records 5 operative Section 301 list measures against China: Section 301 List 1 — China (25%); Section 301 List 2 — China (25%); Section 301 List 3 — China (25%); Legacy China S301 — 9903.88.04 (9903.88.04) (25%); Section 301 List 4A (FYR) — China (8%). Rates, headings, and effective ranges are shown in the table below. (as of 2026-08-28.)
Section 301 additional tariffs apply on top of base HTS duty. The legacy China lists, FYR escalation headings, and forced-labor measure all add percentages rather than replacing base duty. Each measure in the table below lists its `rateExpression` directly from the canonical dataset; verify the rate, scope, and effective dates with USITC HTS and the applicable USTR notice before filing.
Section 301 additional tariffs apply in addition to the base HTS duty rate. For China goods, the total duty is base HTS rate + Section 301 List rate + FYR escalation rate (where applicable). The rates stack, not replace each other. Use the Import Duty Calculator with additional tariff inputs to estimate total landed cost.
The dataset records 0 operative product exclusions. Scope and effective ranges are listed in the table below. Verify the full U.S. note text on USITC HTS before relying on a specific exclusion.
Only the USTR has authority to modify Section 301 tariffs. Importers cannot unilaterally waive or reduce these rates. Exclusions are granted by USTR through a formal process. FYR escalation rates are set by statute and modify automatically on scheduled dates.
Verify Section 301 treatment using the USITC HTS database (hts.usitc.gov), cross-referenced with the applicable USTR Federal Register notices. TariffCatalog provides the Section 301 Tariff Checker tool and Import Duty Calculator for preparation. Final classification decisions should be verified with official sources or a qualified customs broker.
