Beginning January 1, 2025, certain technologies may no longer use high global warming potential (GWP) hydrofluorocarbons (HFCs) or HFC blends. Prohibitions apply to the manufacture, distribution, sale, installation, import, and export of products containing restricted HFCs and on the installation of new systems that use restricted HFCs. More information on the sectors and subsectors, regulatory context, and ongoing rulemakings is available on the Technology Transitions Program website.

*These tables are for informational purposes only and should not be relied on for compliance purposes. Please refer to 40 CFR Part 84, Subpart B for full details.
1. Sale, distribution, and export of these products is prohibited three years after the manufacture and import compliance date.
2. See regulatory text for specific types of aerosol products subject to the later compliance date. Excludes metered dose inhalers using HFC-134a or HFC-227ea or defense sprays using HFC-134a as a propellant.
3. Includes blown foam, products incorporating blown foam, and pre-blended polyol products. Excludes composite structural preformed polyurethane foam for trailer use and for marine use.
4. New products only; does not apply to equipment that is operational during transport.
5. EPA is restricting the installation of new field-assembled systems. Components used to repair existing systems are not subject to these restrictions.
6. New systems with a GWP above 700 can be installed until January 1, 2026, so long as all components are manufactured or imported prior to January 1, 2025 (refer to the Interim Final Rule for additional details).
