WILMINGTON, Del. — The Chemours Co. is halting sales of Freon 404A (R-404A) and Freon 507 (R-507) in the U.S., effective immediately.

Chemours, which invented the Freon and Opteon refrigerants, is making the move in support of regulatory requirements. The strategy aligns with the phasedown of HFCs required by the American Innovation and Manufacturing (AIM) Act and Canada’s Ozone-Depleting Substances and Halocarbon Alternatives Regulations (ODSHAR).

“This decision supports our commitment to creating a better world through the power of our chemistry, advancing decarbonization, circularity, and socioeconomic value through greener solutions industrywide,” said Doug Westerhoff, Americas sales director of Thermal and Specialized Solutions at Chemours, in a press release. “The U.S. AIM Act outlines an ambitious phasedown program that demands a significant reduction in HFC sales and consumption with a targeted 40% phasedown by 2024. This target helped shape the timing of our announcement, and we are confident this decision will contribute significantly to our customers meeting their sustainability targets.”

Chemours continues to work with its customers to provide them with alternatives for their applications and markets, ensuring a smooth and seamless refrigerant transition, the company said in the press release. Opteon XP40, (R-449A) is a solution for existing R-404A and R-507 applications, offering superior performance, energy efficiency, and environmental benefits, the company said. Opteon XL40 (R-454A) and XL20 (R-454C) products are solutions for new equipment that will meet the future Environmental Protection Agency (EPA) technology transition rules, the company said.

Chemours will continue investing in research and development to drive the innovation of next-generation refrigerants and other sustainable solutions, the company said.
