U.S. exports of Difluoromethane (HFC-32) (HS 290342) totaled $6.1M in August 2026, exported to 4 countries.
Last updated: August 2026 dataHFC-32 is a low-global-warming-potential refrigerant increasingly adopted as a replacement for higher-GWP blends in residential and commercial air conditioning systems, classified under 10-digit line 2903421000. India leads US imports under this heading, followed by the United Arab Emirates and Thailand, reflecting the shift of HFC production capacity toward South and Southeast Asia. Like other HFCs, HFC-32 is subject to EPA AIM Act consumption allowance requirements, and importers must ensure their allocations are in order before shipment.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Indian chemical manufacturers have invested significantly in HFC production capacity as global demand for lower-GWP refrigerants has grown. Competitive production costs and proximity to raw material supply chains have positioned Indian producers as major exporters, particularly as the HVAC industry transitions away from higher-GWP blends.
Pure HFC-32 (difluoromethane) classifies under HTS heading 290342. When HFC-32 is blended with other refrigerants to form a mixture (such as R-410A), the blend classifies under a different HTS chapter covering refrigerant mixtures. Importers must confirm whether the shipment is a pure substance or a pre-mixed blend to ensure correct classification.
