Late last month, the White House announced an increase in tariffs on the import of several Chinese products and materials, including steel and aluminum, both of which – especially the latter – are important commodities in the HVAC-R industry and related manufacturing sectors.

As any attendee of February's annual AHR Expo will tell you, conversations on topics pertaining to R-410A's impending phaseout were unavoidable, as next January's deadline for the manufacture and import of new R-410A units looms. And, while the commercial HVAC industry is affected most prevalently by EPA mandates aimed at reducing industry's contribution to climate change, regulation will soon impact several other refrigerants and markets as well.

American chemical giant Chemours announced Thursday that it will discontinue all domestic sales of two of its refrigerant products – Freon™ 404A (ASHRAE designation R-404A) and Freon 507™ (ASHRAE designation R-507) – citing strategic alignment with regulatory phasedown requirements as its reason for doing so. The announcement marks one of the more high-profile developments at the supplier level, especially for R-404A, a longtime mainstay of the commercial refrigeration industry, as the heating and cooling sector continues to act in response to by HFC regulation.
