Annual HFC report: First submissions due March 2026
What do the manufacturers of hairspray cans, foam wall insulation, and ice cream machines have in common? If their products contain hydrofluorocarbons (HFCs), they have to report annually on the HFCs they use, and the first report due date is quickly approaching! Through the Technology Transitions Program, the Environmental Protection Agency (EPA) regulates HFCs used for new products and equipment in three sectors: aerosols, foams, and refrigeration, air conditioning, and heat pumps (RACHP). Among other compliance requirements of the 2023 Technology Transitions Rule, manufacturers and importers of HFC-containing products and equipment must submit annual reports.
Note: EPA’s October 2025 proposed rule to amend the 2023 Technology Transitions Rule doesn’t impact annual reporting requirements.
Use this overview to help you determine whether your business needs to report and, if so, what’s required.
Who reports?
Annual reporting applies to manufacturers and importers of products and equipment that use HFCs. An organization has to submit an annual report if:
- It manufactures or imports a product or component within a regulated sector or subsector (see 40 CFR 84.54), and
- The product or component uses or will use a regulated HFC or HFC blend.
Reporting requirements apply to manufacturers and importers in all sectors and subsectors, and they start with data from calendar year 2025. The first annual report is due to EPA by March 31, 2026.
Note that the annual reporting requirements don’t apply to entities that only:
- Sell or distribute equipment, or
- Install or operate new RACHP systems.
What’s reported?
In each annual report, covered manufacturers and importers must provide:
- The entity’s name and address;
- The entity’s contact person, the contact's email address, and the contact's phone number;
- The calendar year covered by the report and the submission date;
- All applicable North American Industry Classification System (NAICS) codes; and
- A statement certifying that the data is accurate and that the products use HFCs or HFC blends in compliance with the use restrictions and labeling requirements.
Entities in all three sectors also have to report the total mass in metric tons of each HFC or HFC blend contained in all products and components manufactured, imported, and exported annually.
Further, sector-specific standards apply.
| Sector | Requires additional information for: | See 40 CFR: |
|---|---|---|
| Aerosol |
| 84.60(a)(5) |
| Foam |
| 84.60(a)(4) |
| RACHP |
| 84.60(a)(3) |
How’s the report submitted?
According to the latest information shared by EPA in the “Technology Transitions Program: What You Need to Know for January 1, 2025” webinar presentation, the agency is still designing the electronic platform for submitting annual reports. EPA plans to provide reporting instructions and forms before the upcoming deadline.
About the 2023 Technology Transitions Rule
HFCs are greenhouse gases that were developed to replace ozone-depleting substances for use in various products and equipment (primarily refrigeration and air-conditioning systems). The American Innovation and Manufacturing Act of 2020 gives EPA the authority to address HFCs by:
- Phasing down production and consumption through the HFC Allowance Allocation Program,
- Implementing restrictions on HFC use in specific sectors, and
- Developing regulations to maximize the reclamation and minimize the release of HFCs from equipment.
The 2023 Technology Transition Rule established the Technology Transitions Program to restrict HFC uses in sectors and subsectors where lower global warming potential (GWP) technologies are or will soon be available. The regulations apply to manufacturers (including importers), exporters, sellers, distributors, and installers of systems or products in covered sectors that use HFCs.
What about the proposed changes to the 2023 Technology Transitions Rule?
On October 3, 2025, EPA proposed a rule to amend the existing 2023 Technology Transition Rule. However, the proposed changes don’t affect the annual reporting requirements for manufacturers and importers. All covered manufacturers and importers must submit the annual report by March 31, 2026.
The proposed rule impacts specific subsectors, including refrigerated transport, industrial process refrigeration, chillers, retail food (for supermarkets and remote condensing units), cold storage warehouses, and stationary residential and light commercial air conditioning and heat pumps. EPA proposes to:
- Exempt certain intermodal containers transporting cargo at very cold temperatures;
- Extend compliance dates for industrial process refrigeration used in semiconductor manufacturing;
- Raise global warming potential thresholds for remote condensing units, supermarket systems, and cold storage warehouses;
- Extend compliance dates for refrigerated centrifuges and laboratory shakers; and
- Allow existing residential and light commercial air-conditioning and heat pump equipment (i.e., manufactured or imported before January 1, 2025) to continue to be installed.
Key to remember: The first annual reports required by the Technology Transitions Program for manufacturers and importers of HFC-containing products and equipment are due by March 31, 2026.
