US confirms antidumping duties on MSG from Indonesia and China
The US Department of Commerce has continued antidumping duty orders on monosodium glutamate (MSG) imported from Indonesia and China following a sunset review. Commerce and the International Trade Commission determined that revoking these orders would likely cause dumping to resume and harm the domestic MSG industry. Shippers importing MSG from these countries must continue to pay applicable antidumping duties.

According to a notice published in the Federal Register on June 5, 2026, Commerce and the U.S. International Trade Commission jointly determined that "revocation of the antidumping duty (AD) orders on monosodium glutamate (MSG) from Republic of Indonesia (Indonesia) and the People's Republic of China (China) would likely lead to the continuation or recurrence of dumping and material injury to an industry in the United States."
This is a continuation order following a sunset review—a periodic investigation to determine whether existing antidumping duties should remain in place. The orders now remain active indefinitely unless subject to another review.
As a result of the determinations by the U.S. Department of Commerce (Commerce) and the U.S. International Trade Commission (ITC) that revocation of the antidumping duty (AD) orders on monosodium glutamate (MSG) from Republic of Indonesia (Indonesia) and the People's Republic of China (China) would likely lead to the continuation or recurrence of dumping and material injury to an industry in the United States, Commerce is publishing a notice of continuation of these AD orders.
MSG falls under HS Chapter 21 (miscellaneous edible preparations). Importers sourcing MSG from these two countries remain subject to cash deposits or payment of antidumping duties at the time of entry. The specific duty rates are established in the original investigation and remain in effect unless subsequently modified through administrative reviews or changed by Commerce.
This continuation affects all shipments of MSG from Indonesia and China entering US ports. Affected importers include food manufacturers, condiment producers, and distributors using MSG as an ingredient or final product. Customs brokers and freight forwarders handling these imports must ensure proper classification and duty collection at entry.
What this means for shippers
If you import MSG from Indonesia or China, expect antidumping duties to remain due on every shipment. Verify your supplier's exact origin and HS classification (Chapter 21) before shipping. Recalculate landed cost immediately—failure to account for these duties will distort pricing and margin forecasts. Check the Federal Register or Commerce's antidumping-duty database for the current rate applicable to your supplier, then update your cost models. /us-china-tariff-lookup
