US probes imports of R410B

USA: The US Department of Commerce has initiated an inquiry into whether US imports of a refrigerant blend from Mexico are circumventing antidumping duty orders.

The circumvention inquiry targets R410B, a refrigerant blend which closely resembles the air conditioning refrigerant R410A but is not commercially used. R410B is, officially, 45% R32 and 55% R125, as opposed to the 50/50 blend of R410A.

It is alleged by complaints from the US refrigerant manufacturers that R410B is being manufactured in Mexico using R32 and R125 imported from China. It is then being imported in to the US where further processing brings it back in-scope to R410A.

The inquiry will seek to establish whether this is an attempt to circumvent the US antidumping duty order on HFC blends from China established in 2016. This will be the ninth anti-circumvention inquiry initiated since then. 

The Department of Commerce had previously found that “unfinished” HFC blends from China were circumventing the antidumping order, as were HFC blends using Chinese components blended in India. It also found that imports of a patented blend, which were reblended in the United States after importation, were circumventing the order.

In July of this year, the US Department of Commerce initiated several anti-circumvention inquiries to address a claimed 340% increase in the volume of R410B imports originating in China or blended in Turkey from Chinese components. 

The American HFC Coalition claims that such imports can be reblended at a fraction of the cost of manufacturing HFCs. As a result, its members, which include Arkema, Chemours, Honeywell and Mexichem Fluor, suffer depressed prices, declining sales revenues, and lost market share.

As in prior circumvention inquiries, the US Department of Commerce intends to issue questionnaires to solicit information from producers and exporters in Mexico, concerning their shipments to the United States and the origin of any imported HFC blends being further processed into HFC blends.
