Sources monitored

Federal Register

Official publication of all U.S. federal agency rules, including CBP and USTR tariff actions. DutyDesk parses new tariff rules within the next scrape cycle after publication.

CBP (Customs & Border Protection)

U.S. Customs rate database. DutyDesk cross-references CBP's published rate schedule against the HTS codes in your watchlist.

USTR (Trade Representative)

Source of all Section 301 tariff actions, product lists, and exclusion orders. DutyDesk monitors USTR for new actions and exclusion grants/expirations.

Frequently asked questions

How quickly does DutyDesk detect tariff changes?

DutyDesk polls Federal Register, CBP, and USTR sources every 6 hours. Most tariff changes are published in the Federal Register before they take effect, so you typically get 24–48 hours notice before a new rate applies. We send the alert the same scraping cycle we detect the change.

What sources does DutyDesk monitor?

DutyDesk monitors three official U.S. government sources: the Federal Register (for tariff rule publications), CBP (U.S. Customs and Border Protection, for rate schedule updates), and USTR (U.S. Trade Representative, for Section 301 actions and exclusion orders). All data comes directly from official government sources — no third-party feeds.

What kinds of changes trigger an alert?

DutyDesk sends an alert when: (1) the base duty rate on your HTS code changes; (2) a Section 301 tariff rate changes for your product; (3) a new Section 301 exclusion is granted or expires for your HTS code; (4) an antidumping or countervailing duty order is issued or modified that affects your product.
