Do any import or export restrictions apply to HCFC substitutes that do not contribute to ozone depletion, such as HFC-134a or R-410A?
No. Currently there are no restrictions in the United States on the production, import, or export of HFC refrigerants, including R-134a or R-410A. However, importers should expect that U.S. Customs and Border Protection would request verification of contents prior to entering the United States. Also, other countries may have restrictions or requirements for HFC refrigerants exported to them.
