U.S. Finds Chinese Hexamine Is Sold Below Fair Value
Estimated reading time: 4–6 minutes
The U.S. Department of Commerce has determined that hexamethylenetetramine, also known as hexamine, from China is being sold in the United States for less than fair value. This means Chinese hexamine is sold at a lower price in the U.S. than it should be. The period of investigation was from January 1, 2024, to June 30, 2024.
Commerce released its final results on July 18, 2025. There were no comments from businesses or groups about the earlier findings.
Scope of the Investigation
The investigation covered hexamine in granular form from China. It included hexamine with a particle size of 5 millimeters or less, whether it was stabilized, mixed, or blended with other products. Products with at least 50 percent hexamine by weight were included.
China-Wide Entity
For this decision, Commerce used something called “adverse facts available” (AFA) for all Chinese producers or exporters, as no company got a separate rate. This means all hexamine exports from China are treated the same for this case.
Dumping Margin
The final dumping margin for all Chinese producers and exporters has been set at 405.19 percent. The adjusted cash deposit rate, after accounting for subsidies, is 394.65 percent. This means importers must pay a deposit based on this rate when bringing Chinese hexamine into the United States.
Suspension of Liquidation
U.S. Customs will continue to suspend liquidation on hexamine imports from China. This started on May 6, 2025, when the preliminary decision was published. Importers must pay a cash deposit at the rate set by Commerce.
The cash deposit rate may be changed later if the U.S. International Trade Commission (ITC) finds that American producers are hurt by these imports. If ITC makes a final positive injury decision, Commerce will issue an antidumping duty order. If ITC finds no injury, the process will end and deposits will be returned.
Details About the Product
Hexamine is sometimes called HMT, HMTA, or other names. Its chemical formula is C6H12N4. The product covered also includes mixes or blends with at least half hexamine by weight. The U.S. tariff classification for the product is 2933.69.5000.
Next Steps
The case now goes to the U.S. International Trade Commission. The ITC will decide by early September 2025 if the U.S. industry is harmed or threatened by imports of Chinese hexamine. If the ITC finds harm, extra duties will be imposed. If not, the investigation ends with no duties.
Administrative Protective Order
Parties involved in the investigation must handle any business confidential information carefully, as required by law.
