MDI imports could face new duties
The U.S. has opened an antidumping investigation into methylene diphenyl diisocyanate (MDI) imports from China to see if they are being sold in the U.S. at less than fair value. If dumping and injury are found, extra antidumping duties (taxes) could be imposed on imports entered under HTS subheadings including 2929.10.80, 3909.31.00, and several others. The Commission must reach a preliminary determination by March 31, 2025 and transmit its views to the Department of Commerce by April 7, 2025.
Domestic MDI producers seek protection
A petition to start this investigation was filed on February 12, 2025 by the MDI Fair Trade Coalition, consisting of BASF Corporation and The Dow Chemical Company. If the investigation finds dumping and material injury to a U.S. industry, domestic MDI producers could receive trade relief intended to protect U.S. production.
