US trade by year

US imports were $8.5M in the 12 months to Aug 2026, down 80% on the 12 months to Aug 2018. US exports were $12.3M, down 52%. In January 2022 the HS 2022 revision moved some goods between this code and 8549.21, 8549.29, 8549.31 and 3 more, so part of a change across the dashed line can be the revision. This code began with the HS 2017 revision in January 2017, taking goods from 8460.21 and 8460.90, so its history starts there. Dotted lines mark lasting changes in duty paid, labelled with the supplier, or "Duty" when several moved; the tariff timeline lists each one with its notices.
