Per the EPA’s American Innovation and Manufacturing (AIM) Act, as of January 1, 2025, the agency is limiting the use of HFCs with a Global Warming Potential (GWP) greater than 150 in aerosol products.
Please note, 152a has a GWP of less than 150 GWP and thus it is not restricted under this rule.
However, there is an exception; aerosol products in the following categories will have until January 1, 2028, to comply. As of January 1, 2028, all aerosols can only use HFCs with a GWP of 150 or less. This includes an extension for the use of HFC-43-10 mee and HFC-245fa in aerosols until January 1, 2028.
152a has a GWP of less than 150 and thus it is not restricted under this rule.
Products within these categories will have until January 1, 2028, to comply.
