Results come from the CUSMA rule release and measure set named on each page, approved and released by FSRC; each rule’s review note says whether a licensed reviewer has read it. Duty figures are estimates, and the determination of origin is made at the customs entry.

Rule release cusma-annex4b-2026-11-r5 is served: 3,090 rules, 1270 of them with a regional value content requirement; 62 provisions of Annex 4-B it does not carry yet, for which the engine gives no result.
