On March 31, 2025, the U.S. Department of Commerce (DOC) announced its final affirmative determinations in the anti-dumping (AD) investigation on epoxy resins imported from China, India, South Korea, Thailand, and Taiwan (China).
Because Chinese companies did not participate in the investigation, the DOC applied adverse facts available, assigning a dumping margin of 354.99% to Chinese producers/exporters. The final dumping margins for other regions are as follows:
India: 12.69% – 15.68%
South Korea: 5.62% – 7.59%
Thailand: 5.25%
Taiwan (China): 10.93% – 26.98%
At the same time, the DOC issued its final countervailing duty (CVD) determinations on epoxy resins imported from China, India, South Korea, and Taiwan (China). Due to non-cooperation, Jiangsu Sanmu Group Co., Ltd., Shandong Bluestar Dongda Chemical Co., Ltd., and all other Chinese producers/exporters were assigned a countervailing duty rate of 547.76%.
The final CVD rates for other regions are:
India: 10.66% – 103.72%
South Korea: 1.01% – 1.84%
Taiwan (China): 3.38% – 19.13%
The U.S. International Trade Commission (ITC) is expected to issue its final injury determinations for both the anti-dumping and countervailing duty cases on May 12, 2025. If affirmative, the duties will be formally imposed.
The products involved fall under U.S. Harmonized Tariff Schedule (HTS) code 3907.30.0000.
Previously, on April 23, 2024, the DOC initiated anti-dumping and countervailing duty investigations on epoxy resins imported from China, India, South Korea, and Taiwan (China), and an anti-dumping investigation on imports from Thailand.
