5 Regions Face Mixed Verdicts as US Rules on $3907 Epoxy Resin Imports

In a pivotal decision on April 30, the U.S. International Trade Commission (ITC) delivered a split outcome for epoxy resin exporters from five countries and regions. The commission ruled that imports from China and India do not threaten or harm domestic producers, effectively ending the anti-dumping and countervailing duty investigations for those two nations.

However, the ITC issued affirmative injury determinations for epoxy resins from South Korea, Thailand, and Taiwan, concluding that these imports materially damage or threaten the U.S. industry. This means the U.S. Department of Commerce will impose anti-dumping duties on products from all three, and countervailing duties on shipments from Korea and Taiwan.

These actions affect products classified under customs code 3907.30.0000, a category widely used in coatings, adhesives, and composites.

The trade review process began on April 23, 2024, when the Commerce Department launched investigations targeting epoxy resins from China, India, Korea, and Taiwan for both dumping and subsidies, and Thailand for dumping alone. On March 31, 2025, the Commerce Department concluded that dumping and subsidization had indeed occurred, but ITC’s latest vote limits the scope of enforcement.

For Chinese and Indian exporters, the ruling brings relief amid increasing scrutiny on chemical exports. But Korean, Thai, and Taiwanese producers now face tariffs that could significantly alter their access to the U.S. market.

The outcome underscores the growing complexity of global chemical trade enforcement and highlights how each region’s practices are being examined with greater precision.
