US Imposes 213.44% Anti-Dumping Duty on China PTMEG from November 10, 2026

November 11, 2026 2 min read

November 10, 2026 — The US Department of Commerce has published a duty notice in the Federal Register confirming a 213.44% anti-dumping duty on polytetramethylene ether glycol (PTMEG) originating in China, after the US International Trade Commission (ITC) issued a preliminary affirmative injury determination in the anti-dumping investigation.

Scope: The rate applies to all Chinese producers and exporters.

Effective date: The duty takes effect on November 10, 2026, US Eastern Time.

Commerce preliminarily determined that PTMEG from China is being sold in the US market at less than normal value — that is, it is being dumped.

Commerce will instruct US Customs and Border Protection (CBP) to suspend liquidation of imports of the subject merchandise (or withdrawals from warehouse for consumption) from November 10, 2026, and to require cash deposits equal to 213.44% of the value of the goods.

Notably, the US also issued preliminary affirmative anti-dumping determinations on the same product from Korea, Vietnam and Taiwan, China, and will levy anti-dumping duties at the following rates:

• Korea: 25.32%–49.79%
• Vietnam: 36.55%
• Taiwan, China: 7.46%–26.42%

Product scope: Polytetramethylene ether glycol (PTMEG).

• All forms of PTMEG, irrespective of physical form, purity, molecular weight, hydroxyl number, acid number, color, density, softening point, glass transition temperature, flash point, water content, viscosity and packaging.
• PTMEG mixed with other products, provided the components are merely blended and do not react chemically to form a different product. In such mixtures, only the PTMEG component is covered.
• Merchandise matching the above description that is processed in a third country — including mixing, dilution, addition or removal of stabilizers, modifiers or additives, or other processing that does not remove the merchandise from the scope.
• In products blended or mixed with PTMEG from non-subject sources, only the component from subject sources is covered.

The merchandise is primarily classified under US Harmonized Tariff Schedule subheading 3907.29.0000, but may also be imported under 2932.11.0000 and 3404.91.5150. The written description controls over the tariff classification.

PTMEG is mainly used to produce spandex fiber, thermoplastic polyurethane, elastomers, adhesives, sealants and coatings.

According to official US import statistics released by Commerce, the US imported about 35,251 tonnes of the product from China in 2023, valued at USD 54.8 million; 39,800 tonnes in 2024, valued at USD 57.93 million; and 26,983 tonnes in 2025, valued at USD 35.19 million.

Imports from China ran at roughly 35,000–40,000 tonnes a year in 2023–2024, worth some USD 55–58 million, before falling sharply to about 27,000 tonnes and USD 35.2 million in 2025.

Among the four countries subject to the duties, China is a major supplier but not the largest. Korea shipped the most to the US — about 82,000 tonnes worth USD 153 million in 2025 — far exceeding China.

The 213.44% anti-dumping duty will deal a substantial blow to Chinese exports to the US, potentially erasing them altogether.
