Site launched with the post-24-July rule set
First publication. The dataset was built from primary sources on 1 August 2026 and reflects three changes that most other guidance has not caught up with: IEEPA reciprocal tariffs were terminated on 20 February 2026, the 10% Section 122 surcharge expired on 24 July 2026, and Section 301 forced-labour tariffs of 10%–12.5% took effect the same day across 60 economies. De minimis is suspended for every mode.

FY2027 customs user fees loaded ahead of time
CBP published the FY2027 fee adjustment on 31 July 2026. Both schedules are in the dataset with a changeover date, so estimates dated on or after 1 October 2026 already use the new figures — the informal entry fee rises from $2.69 to $2.77 and the express consignment fee from $1.34 to $1.38.
