Published Date: 4/29/2026
Notice
Summary
The U.S. Department of Commerce found that some Japanese companies sold glycine at unfairly low prices from June 2023 to May 2024. Because of this, certain importers might have to pay extra duties to level the playing field. These final results take effect on April 29, 2026, so businesses should get ready for possible changes in costs and rules.

Analyzed Economic Effects
5 provisions identified: 0 benefits, 5 costs, 0 mixed.
Resonac Hit with 86.22% Duty
The Department of Commerce found that Resonac Corporation is the successor-in-interest to Showa Denko and assigned Resonac an estimated weighted-average dumping margin of 86.22 percent for sales of glycine during June 1, 2023 through May 31, 2024. This final result is applicable April 29, 2026 and could raise duties or cash deposit requirements for imports linked to Resonac.
Cash Deposit Rates Take Effect
Upon publication of these final results (applicable April 29, 2026), cash deposit requirements for glycine shipments entered or withdrawn for consumption on or after that date will be set equal to the company-specific weighted-average dumping margins established in this review; the all-others rate remains 53.66 percent. These cash deposit rates remain in effect until further notice.
YGK/Nagase Assigned 9.84% Duty
Commerce determined that Yuki Gosei Kogyo Co., Ltd./Nagase & Co., Ltd. (YGK/Nagase) have an estimated weighted-average dumping margin of 9.84 percent for glycine sold during June 1, 2023 through May 31, 2024. This margin applies under the final results effective April 29, 2026 and may increase duties or required deposits for imports tied to YGK/Nagase.
File Reimbursement Certificate or Risk Doubled Duties
Importers are reminded of their obligation under 19 CFR 351.402(f) to file a certificate regarding reimbursement of antidumping duties prior to liquidation of relevant entries during the period of review. Failure to file the certificate could lead Commerce to presume reimbursement occurred and result in assessment of doubled antidumping duties.
Timing for Duty Assessment and Liquidation Holds
Commerce intends to instruct U.S. Customs and Border Protection (CBP) to assess antidumping duties on appropriate entries no earlier than 35 days after publication of these final results (publication April 29, 2026). If a timely summons is filed at the U.S. Court of International Trade, the instructions will direct CBP not to liquidate relevant entries until the time for a statutory injunction has expired (i.e., within 90 days of publication).
