Last updated: April 2026 dataHFC-245fa is a low-pressure blowing agent widely adopted by the rigid polyurethane foam industry as a replacement for ozone-depleting HCFC-141b, making it a critical input for insulation panel and appliance manufacturers. Japan leads US imports under tariff line 2903471000, followed by Mexico and Canada. Because Canada and Mexico supply under USMCA, importers sourcing from those origins may benefit from preferential duty treatment. EPA tracks these compounds under its HFC phasedown framework established by the AIM Act.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The dominant end use is as a blowing agent for closed-cell rigid polyurethane foam, particularly in building insulation panels and commercial refrigeration equipment. Demand tracks closely with construction activity and appliance manufacturing cycles.
Yes. The American Innovation and Manufacturing (AIM) Act authorizes EPA to phase down HFC production and consumption, including HFC-245fa. Importers should monitor EPA's allocation and phasedown schedules, as future import volumes may require allowances or be subject to restrictions.
