U.S. exports of mixtures containing other hfcs, excluding cfcs and hcfcs, nesoi (HS 382769) totaled $274K in June 2026, traded with 2 countries.
Hydrofluorocarbon blends that contain HFCs outside the 2903.41–2903.48 range — and no CFCs or HCFCs — and that are not captured by any more specific 3827 subheading are classified here as a final NESOI residual. Belgium, Spain, and the United Kingdom are the leading US suppliers, pointing to a predominantly European origin profile for these specialty blends, which often serve niche industrial, pharmaceutical aerosol, or specialty cleaning applications. EPA SNAP and AIM Act allowance frameworks still apply where the HFC components are covered substances, and importers should confirm the specific HFC identities in the blend to assess regulatory obligations accurately.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
This residual subheading tends to capture blends used in pharmaceutical metered-dose inhaler propellants, precision electronics cleaning, specialty foam blowing, and certain laboratory or analytical applications — end uses that require specific HFC compositions not covered by the mainstream refrigerant blend subheadings. The European supplier profile reflects established pharmaceutical and specialty chemical industries in Belgium, Spain, and the UK.
AIM Act allowance requirements apply to HFCs listed as regulated substances under the program. The importer should identify each HFC component in the blend by chemical name and CAS number and cross-reference against EPA's list of regulated HFCs. If any component is a regulated substance, consumption allowances must be held for that component's mass in the shipment, regardless of the blend's overall classification.
