Check duty impact, review official notices, and save source-linked email alerts for the HTS codes that actually move your shipments — without a brokerage login.
Enter a code or product phrase, choose origin, and get a source-linked estimate before you save an alert.
6404.20.40 from China — estimated duty stack.Save 6404.20.40 to get an email when a monitored official source changes treatment, timing, or review status for this code.
Each row links to the official notice and shows whether the parsed signal is ready for action or still needs a broker or compliance review.
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.
CBP CSMS 68855869 implements the June 1, 2026 Section 232 metals proclamation for steel, aluminum, copper, and derivative articles. The guidance adds new derivative classifications, confirms June 8, 2026 effective dates for several 9903.82 headings, lowers the U.S.-content threshold for the reduced U.S.-metal pathway from 95% to 85%, and keeps this row as a source-watch trigger because no current catalog HTS code is itself a listed Section 232 metals line.
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 and CBP records for review, so a watched code becomes an investigation queue rather than an automatic duty conclusion.
No account needed for the checker. Save a code only when you want an email when an official source moves.
Paste an HTS code (8–10 digits) or describe the product. We surface candidate classifications drawn from the official tariff schedule.
We show the base column rate plus the country overlay (e.g., Section 301), with caveats and a link straight to the USITC entry — never a black-box number.
When a monitored official source changes treatment for the code — Federal Register, USTR, CBP, Commerce — your inbox gets the diff with the link.
Code pages keep the duty columns, official links, classification caveats, country scenarios, and related source changes in one place.
When USTR, CBP, Commerce, or USITC publish anything that changes treatment, timing, or scope for a saved code — we send the diff with the official link. No marketing, no speculation.
