The following is provided by Global Affairs Canada (GAC).
Please be advised that the wheat products tariff rate quota (TRQ) has been deemed filled as of January 12, 2025. Consequently, accounting for imports of all wheat products classified under a “within access commitment” tariff item number after January 12, 2025 (at 20:59 pm Ottawa time (EST) must be resubmitted. All imports of wheat products accounted for after the cut-off date are classified at the “over access commitment” tariff item number, even if they were imported, (or imported and released), before the quota has been filled.
Please note that after the TRQ level is reached, some wheat products that qualify under the U.S., Mexican, Chilean, Peruvian, Costa Rican, European or United Kingdom’s tariff will continue to be assessed at the “within access” lower rate of duty.
