Recent official changes mapped to affected HTS codes.
Tariff Sentinel tracks official notices, guidance, and risk signals — then highlights the codes and source notes that may need attention. Use this feed as a triage queue.
As of Aug 4, 2026, Tariff Sentinel is tracking 5 source-linked U.S. tariff changes across Section 301, Section 232, and AD/CVD — each mapped to the affected HTS codes, origin countries, effective dates, and the controlling Federal Register or agency source. This is HTS update news tied to a specific code and entry date, not a general trade-headline feed.
Where to find the latest HTS update news
Official U.S. tariff and HTS changes are published across several government surfaces: the Federal Register (the controlling legal record for USTR Section 301 actions and Commerce AD/CVD determinations), USTR’s tariff-actions and four-year-review pages, U.S. Customs and Border Protection’s Cargo Systems Messaging Service (CSMS) for entry-filing instructions, and the USITC Harmonized Tariff Schedule for the codes and Chapter 99 headings themselves. This feed consolidates those signals and maps each notice back to the watched HTS code, origin, effective date, and review status, so an “HTS update” becomes something you can check against a specific shipment rather than a headline to chase. Official sources source-checked through Aug 4, 2026.
How to read this feed
Each row starts with the program and severity, links the official source, and maps the notice to watched HTS codes, countries, effective dates, and review status. Broad notices are useful for early warning; product-specific notices still need a broker or compliance review before a final duty change is assumed. See the source methodology for how broad notices are downgraded to review notes.
USTR's July 23 final action imposes new country-specific Section 301 duties on most imports from 60 economies beginning at 12:01 a.m. eastern time on July 24, 2026. Seventeen economies receive an additional 10% rate; products of the European Union and Taiwan are capped at a 10% combined MFN-plus-Section 301 rate; products of Japan, South Korea, and Switzerland are capped at 12.5%; and the other 38 economies receive an additional 12.5%. New Chapter 99 headings 9903.05.20–9903.05.84 apply the country rates, while headings 9903.05.85–9903.06.21 implement in-transit, product, Section 232, trade-agreement, and economy-specific exemptions. Because the exemption annex is product- and origin-specific, a base HTS code alone does not settle coverage.
The Notice of Action published as filed on July 20, 2026 at 91 FR 45516 (pages 45516–45615), imposing an additional 25% ad valorem duty on nearly all products of Brazil under new HTS Chapter 99 heading 9903.05.01, effective for goods entered for consumption on or after 12:01 a.m. eastern time on July 22, 2026. Cargo already on the water gets exactly seven days: the in-transit exception in heading 9903.05.02 holds only if the goods were in transit on their final mode before 12:01 a.m. ET July 22, 2026 AND are entered for consumption before 12:01 a.m. ET July 29, 2026. The duty stacks on the normal Column 1 rate and on any antidumping or countervailing duty; goods already subject to Section 232 tariffs (steel, aluminum, copper, vehicles and parts, wood products, semiconductors) are carved out through heading 9903.05.07. This is a separate Section 301 investigation from the China technology-transfer actions that govern this catalog's codes, so it does not change any China-origin overlay.
USTR initiated a review process that can later affect China-origin tariff actions and exclusions; the initiation notice itself does not change duty rates. Saved-code monitoring flags potentially affected HTS codes, links back to the official notice, and gives import teams a starting point for broker review before purchase orders or landed-cost assumptions change.
As of August 4, 2026, the current U.S. Harmonized Tariff Schedule uses 26 Section 232 metals headings — 9903.82.01 through 9903.82.26 — to route steel, aluminum, copper, and derivative articles to treatments ranging from no change to an additional 50%. The correct heading still depends on U.S. note 16, metal content, origin, base duty, and entry date; this source-linked map is a review aid, not a filing determination.

AD/CVD scope cannot be determined from HTS code alone. Tariff Sentinel flags possible source overlap for footwear and footwear-component imports and sends users to Commerce, CBP, and USITC records for review, so a watched code becomes an investigation queue rather than an automatic duty conclusion.

Official U.S. HTS and tariff changes are published in the Federal Register (the controlling record for USTR Section 301 actions and Commerce AD/CVD determinations), on USTR's tariff-actions and four-year-review pages, through U.S. Customs and Border Protection's Cargo Systems Messaging Service (CSMS) for entry-filing instructions, and in the USITC Harmonized Tariff Schedule for the codes and Chapter 99 headings. This feed consolidates those sources and maps each notice to the affected HTS codes, countries, and effective dates. As of Aug 4, 2026 it tracks 5 source-linked changes across Section 301, Section 232, and AD/CVD.
How often is this tariff change feed updated?
Every entry records the date its official source was last checked — shown on each row and summarized at the top of the page. Tariff Sentinel re-checks tracked notices against their controlling Federal Register, USTR, CBP, and USITC sources on a recurring cadence and updates the entry, and its source-checked date, when the official record changes. The most recent source check in the current feed is Aug 4, 2026.
What tariff programs does this HTS change feed cover?
The feed currently covers Section 301, Section 232, and AD/CVD. Section 301 entries track the China tariff lists and the second statutory four-year review USTR opened in May 2026; Section 232 entries track steel and aluminum national-security tariffs; and AD/CVD entries track antidumping and countervailing scope-risk signals. Each entry links the official notice and maps it to the specific HTS codes and origin countries it affects, so a broad program change resolves to the exact code and entry date you need to check.
Feed last updated: Aug 4, 2026. Each entry links its official source and shows the date that source was last checked. Broad notices are useful for early warning, but confirm the controlling Federal Register notice and current Chapter 99 treatment for your entry date with a broker or compliance review before assuming a final duty change. See the source methodology for how notices are verified and downgraded to review notes.
