U.S. exports of Mixtures Containing Trifluoromethane (HFC-23) (HS 382751) totaled $201K in August 2026, exported to 1 country.
Last updated: August 2026 dataHFC-23 (trifluoromethane) is a potent greenhouse gas with an extremely high global warming potential, generated primarily as a byproduct of HCFC-22 production, and mixtures containing it are classified under tariff line 3827510000. Unlike ozone-depleting substances, HFC-23 is not controlled under the Montreal Protocol's original framework but is addressed under the Kigali Amendment, and its trade is increasingly scrutinized under climate-related regulatory initiatives. China is the dominant global source, with the United Kingdom, Germany, and South Korea also appearing among US suppliers. Importers should monitor evolving EPA and international climate regulations that may impose additional controls on high-GWP HFC mixtures.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
No. HFC-23 is not an ozone-depleting substance and is not currently subject to EPA ODS consumption allowances under the Clean Air Act's Section 605/606 framework. However, it is a potent greenhouse gas regulated under the Kigali Amendment to the Montreal Protocol, and US domestic HFC regulations under the AIM Act may increasingly affect its trade and use. Importers should track EPA rulemaking under the AIM Act for any emerging import controls.
HFC-23 is generated as an unavoidable byproduct during the manufacture of HCFC-22. Because it is not intentionally produced, its availability is tied to HCFC-22 production volumes, which are themselves declining under phase-down schedules. Importers sourcing HFC-23 mixtures — particularly from China, the dominant producer — should obtain documentation confirming the material's origin as a captured byproduct and verify that the exporting facility complies with applicable destruction or recovery obligations under the Kigali Amendment.
