In the United States, refrigerants that harm the earth’s ozone layer – commonly called
“ozone-depleting substances” or ODS – are regulated by the U.S. Environmental Protection
Agency (EPA) and some US states. Regulated refrigerants include substances that EPA has
classified as “Class I” or “Class II” ODS, any substance that includes a Class I or Class II
ODS, and “Substitutes” for ODS. At a high level:
-
Class I and Class II ODS: EPA publishes a
complete list of Class I and Class II ODSs. Some of the more common Class I ODS are R-12, halon, and methyl bromide.
Some of the more common Class II ODS are Freon (also called R-22 and HCFC-22) and HCFC 142b
-
Substitute Refrigerants: EPA publishes lists of
Substitute
Refrigerants that are acceptable, acceptable with use restrictions, or
unacceptable. Substitute Refrigerants are a broad category and generally includes
chemicals and products that are used as substitutes for Class I and Class II ODS to cool
and transfer heat. Some common Substitutes acceptable with use conditions include R-134a
and R-441a
Except for a few very narrow exceptions, Class I ODS, Class II ODS, and Substitute
Refrigerantss can only be sold, distributed, or offered for sale or distribution to buyers
who have been certified as technicians through EPA-approved certification programs. These
products are not permitted for sale on Amazon
The sale and distribution restrictions do not apply to a limited number of exempt
substances that can be used for cooling and heat transfer. Examples of Exempt Refrigerants
include the following: (1) carbon dioxide (R-744) used as a refrigerant; (2) nitrogen
(R-728) used as a refrigerant; and (3) refrigerants used for motor vehicle air conditioners
(MVAC) in a container with a self-sealing valve designed to hold two pounds (32 oz) or
less.

self-sealing containers designed to hold 2 pounds (32 oz) or less if the refrigerant is
not a Class I or Class II ODS. These products must clearly state the refrigerant, its use,
the container size, and the valve type (for example, R-134a for MVAC use in a 20-ounce
self-sealing container) Note: some EPA Exempt Refrigerants may be subject to additional
state restrictions due to local laws.
