56.54% antidumping duty for China MSG
If you import monosodium glutamate (MSG) from China (including Ajinoriki), Commerce set the antidumping duty (AD) rate at 56.54%. That 56.54% rate applies to assessment and to cash deposits for shipments entered or withdrawn for consumption on or after June 16, 2026; Commerce intends to issue assessment instructions to U.S. Customs and Border Protection (CBP) no earlier than 35 days after publication.
Importer certification to avoid double duties
Importers must file a certificate about whether antidumping duties were reimbursed before liquidation of the relevant entries, under 19 CFR 351.402(f)(2). If you fail to file this certificate, Commerce may presume reimbursement occurred and assess double antidumping duties.
Blends with 15%+ MSG covered by order
MSG is covered by the antidumping order even when blended or in solution with other products if the resulting mix contains 15% or more MSG by dry weight. That means blended seasonings, powders, or solutions with at least 15% MSG can be subject to the 56.54% duty.
