China Faces New Probe on Tris Chemical Subsidies
Published Date: 5/18/2026
Notice
Summary
The U.S. is starting an investigation into whether imports of Tris from China are unfairly helped by government support, which could lead to extra taxes on those imports. This affects Chinese exporters and U.S. producers like Advancion Corporation, aiming to keep things fair in the market. The investigation kicked off on May 11, 2026, and could impact prices and trade soon.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 1 costs, 1 mixed.
CVD Investigation Started for Tris Imports
On May 11, 2026, the U.S. Department of Commerce opened a countervailing duty (CVD) investigation into imports of Tris (from China) to determine if those imports receive government subsidies. If Commerce and the U.S. International Trade Commission find subsidies and material injury, the investigation could lead to countervailing duties (extra taxes) on those imports; Commerce will make a preliminary determination no later than 65 days after initiation, and the ITC will preliminarily rule within 45 days after the petition was filed.
Products and Customs Codes Covered
The investigation’s scope covers tris(hydroxymethyl)aminomethane (Tris, CAS 77-86-1) and Tris hydrochloride (Tris HCl, CAS 1185-53-1) in all grades, purities, forms, and packaging, and references HTSUS subheading 2922.19.9690. Tris HCl manufactured in a third country using Tris produced in China, and merchandise that is merely reprocessed (e.g., recrystallized, retested, or repackaged) in a third country, remains subject to this investigation.
Opportunity and Deadlines to Comment
Commerce set deadlines for interested parties to submit scope comments: initial scope comments are requested by 5:00 p.m. Eastern Time on June 1, 2026, and rebuttal comments by 5:00 p.m. Eastern Time on June 11, 2026; comments must be filed electronically via ACCESS. Commerce also released U.S. Customs and Border Protection (CBP) import data and stated parties wishing to comment on that data or respondent selection must do so within three days of the notice’s publication.
