Difluoromethane (R-32) from China injures U.S. industry, says USITC

Christian Fernsby |

As a result of the Commission’s affirmative determination, Commerce will issue an antidumping duty order on imports of this product from China.

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.
