China Initiates Review of its Antidumping Duty Measure on Ethylene Propylene Diene Monomer (EPDM) from the United States, the European Union, and South Korea
China Initiates Review of its Antidumping Duty Measure on Ethylene Propylene Diene Monomer (EPDM) from the United States, the European Union, and South Korea
On December 19, 2025, China’s Ministry of Commerce (MOFCOM) initiated an expiry review of its antidumping duty measure on imports of ethylene propylene diene monomer (EPDM) from the United States, the European Union, and South Korea. MOFCOM’s AD measure on EPDM has been in place since December 20, 2020. The AD duties currently in place for U.S. producers/exporters range from 214.9% to 222%.
What is an expiry review?
An expiry review is also known as a sunset review, and its purpose is to determine whether the revocation of the AD measure would be likely to lead to the continuation or recurrence of dumping or unfair subsidization and material injury to the domestic industry. The measure may only be extended beyond five years, counting from the date on which a measure was first instituted or the most recently completed expiry review, if both conditions are met.
