The American Hydrofluorocarbon (HFC) Coalition this month filed an antidumping duty petition charging that unfairly traded imports of R-134a from China are causing material injury to the U.S. fluorochemicals industry. The petition was filed concurrently with the United States Department of Commerce and the United States International Trade Commission (USITC). The American HFC Coalition alleges dumping margins for R-134a ranging from 150 percent to over 200 percent.

A hydrofluorocarbon refrigerant gas, R-134a is used in large chillers in commercial buildings, home refrigerators, aerosols, propellants, automobiles and other applications. HFC Coalition filed the petition in response to large and increasing volumes of low priced imports from China.

This is the second antidumping petition filed by the HFC Coalition. The first was filed June 25, 2015, and seeks relief from Chinese imports of R-410A and other HFC blends. The HFC blends covered by the first case are the primary refrigerants used in home air conditioning and supermarket refrigeration. As a result of the first petition, the Department of Commerce recently issued preliminary results, imposing antidumping duties ranging from 91.99 percent to 210.46 percent.

China has constructed sufficient HFC capacity to supply its own market as well as the entire U.S. market four-times over, says HFC Coalition.
