The United States International Trade Commission (USITC) today determined that a U.S. industry is materially injured by reason of imports of difluoromethane (R-32) from China that the U.S. Department of Commerce (Commerce) has determined are sold in the United States at less than fair value.
Chair Jason E. Kearns, Vice Chair Randolph J. Stayin, and Commissioners David S. Johanson, Rhonda K. Schmidtlein, and Amy A. Karpel voted in the affirmative.
As a result of the Commission’s affirmative determination, Commerce will issue an antidumping duty order on imports of this product from China.
The Commission’s public report Difluoromethane (R-32) from China (Inv. No. 731-TA-1472 (Final), USITC Publication 5165, March 2021) will contain the views of the Commission and information developed during the investigation.
The report will be available by March 23, 2021; when available, it may be accessed on the USITC website at: http://pubapps.usitc.gov/applications/publogs/qry_publication_loglist.asp.

Difluoromethane from China
Investigation No. 731‐TA‐1472 (Final)
Product Description: R-32 is a hydrofluorocarbon (HFC), a colorless, odorless, gaseous chemical that is primarily used as a component in HFC blends. Once blended, these gases are used for various residential and commercial refrigerant and cooling applications. Apart from ‘R-32’, difluoromethane has other names, including HFC-32, FC-32, Freon-32, methylene difluoride, methylene fluoride, carbon fluoride hydride, halocarbon R32, fluorocarbon R32, and UN 3252. Compared to other HFC components, R-32 has a relatively lower global warming potential, no ozone depletion potential, and is a low-to-medium temperature refrigerant.
