The U.S. Department of Commerce has unleashed a crushing blow in the Japanese Glycine Antidumping lawsuit, slapping Resonac Corp. with a punishing 86.22% antidumping duty on imports after ruling the supplier failed to cooperate with its investigation. The decision, announced Thursday, could reshape trade flows in the chemical industry, where glycine—an amino acid widely used in food, pharmaceuticals, and industrial applications—plays a pivotal role.
The department said the duty, set to take effect Friday, reflects adverse inferences drawn from Resonac’s lack of cooperation, a move that effectively pushed the penalty sky-high.
Other Japanese Firms Face Lighter, but Significant, Penalties
Not all Japanese suppliers were hit as hard. Yuki Gosei Kogyo Co. Ltd. and Nagase & Co. Ltd., both named in the Commerce review, were handed a 9.84% antidumping rate—serious, but a far cry from the crushing tariff now imposed on Resonac.
The investigation stretched across a full year beginning in June 2023, with several Japanese glycine exporters initially included but later removed at the request of the U.S. petitioner, Chattem Chemicals Inc.
