Washington Investigates Whether Chinese PTMEG Is Priced Too Low
Published Date: 11/10/2026
Notice
Summary
The U.S. Department of Commerce has found that a chemical called polytetramethylene ether glycol (PTMEG) from China is likely being sold in the U.S. for less than it should be. This means they might add extra fees to Chinese imports to keep things fair for American businesses. This decision covers sales from October 2025 to March 2026 and kicks in starting November 10, 2026.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 3 costs, 0 mixed.
Preliminary Finding: 213.44% Dumping Margin
The Department of Commerce preliminarily found that polytetramethylene ether glycol (PTMEG) from China is being sold in the U.S. at less than fair value for the period October 1, 2025 through March 31, 2026. Commerce preliminarily assigned a China-wide estimated weighted-average dumping margin of 213.44 percent, based on adverse facts available (AFA).
Cash Deposits and Suspension of Liquidation Start
Beginning on the date this notice was published in the Federal Register (November 10, 2026), U.S. Customs and Border Protection will suspend liquidation of PTMEG entries and require a cash deposit equal to the estimated dumping margin. For Chinese producers/exporters treated as part of the China-wide entity, and for third-country exporters supplied by that China-wide entity, the cash deposit rate will be equal to the China-wide rate (213.44%). These instructions will remain in effect until further notice.
Products Covered: PTMEG and Specified Blends
The investigation covers polytetramethylene ether glycol (PTMEG) in all forms, including blends with stabilizers, modifiers, or additives so long as those additives collectively account for no more than two percent of the blend by weight. The scope references CAS number 25190-06-1 and HTSUS subheading 3907.29.0000 (and notes possible related subheadings 2932.11.0000 and 3404.91.5150).
