China Hexamine: Details of AD/CV Duty Orders
The Commerce Department is issuing antidumping duty and countervailing duty orders on hexamethylenetetramine (hexamine) from China (A-570-180/C-570-181). The orders, released Sept. 10, set permanent antidumping and countervailing duties, which will remain in place unless revoked by Commerce in a sunset or changed circumstances review. Commerce will now begin conducting annual administrative reviews, if requested, to determine final assessments of AD/CVD on importers and make changes to cash deposit rates.

The order details a “gap period” of no CVD liability for subject merchandise entered July 5, 2025 - Sept. 7, 2025, and of no AD liability for subject merchandise entered Sept. 3-7, 2025. Commerce may only suspend liquidation for a four-month period after its preliminary CVD determination, issued March 7, 2025, and for four months after its preliminary AD determination (extendable upon request to six months but not extended in this case), issued May 6, 2025, without an International Trade Commission final affirmative injury determination in place. Commerce will order CBP to liquidate, without regard to AD or CVD, any entries during these respective gap periods.
Subject merchandise entered during the CVD gap period but outside the antidumping duty gap period (i.e., July 5, 2025, through Sept. 2, 2025) will be assessed only antidumping duties.
AD/CVD Suspension of Liq Instructions
Suspension of liquidation resumes for all entries of subject merchandise entered on or after Sept. 8, the date that the final ITC affirmative injury determination was published.
