China's Sneaky Acid Powder Faces U.S. Duties in Trade Rule Crackdown
Published Date: 2/23/2026
Notice
Summary
The U.S. Department of Commerce has officially decided that certain acidic powder forms of a chemical called HEDP from China are sneaking around existing trade rules. This means importers of this product from China will face extra duties starting February 23, 2026, protecting U.S. companies from unfair pricing. If you’re involved in importing or selling HEDP, get ready for changes that could affect costs and supply.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 3 costs, 0 mixed.
Extra Duties and Cash Deposits for Importers
If you import acidic (non-neutralized) solid HEDP from China, U.S. Customs and Border Protection will suspend liquidation and require cash deposits for estimated antidumping and countervailing duties on entries of this product. The suspension and cash deposit requirement apply to entries entered or withdrawn from warehouse for consumption on or after December 19, 2024, and the determination is effective February 23, 2026.
Country-Wide Application to Chinese Producers
Commerce applied its affirmative circumvention determination on a country-wide basis, meaning acidic solid HEDP produced in and exported from the People's Republic of China is treated as circumventing the existing orders regardless of the specific Chinese producer or exporter.
Protection for U.S. HEDP Producers
Commerce's determination is intended to protect U.S. companies from unfair pricing by treating acidic solid HEDP from China as circumventing the antidumping and countervailing duty orders. This action directs CBP to suspend liquidation and collect cash deposits for the subject merchandise.
Use of Adverse Facts Available (AFA)
Commerce states it relied on facts available, including adverse inferences (AFA), with respect to all known Chinese producers and exporters of acidic solid HEDP because those parties failed to respond to Commerce's information requests.
