Import Tips & Compliance
• DOT/UN cylinder certification required; include test dates and pressure ratings on shipping documents
• File EPA Form 3520-21 for ozone-depleting substance imports with allocation allowance numbers
• Avoid declaring as 'CFC' which triggers different regulatory regime than HCFCs

HCFC-141b (1,1-Dichloro-1-fluoroethane)
HCFC-141b is a hydrochlorofluorocarbon used primarily as a blowing agent in polyurethane foam production and as a solvent for cleaning electronics. It is a halogenated derivative of acyclic hydrocarbons containing both chlorine and fluorine, specifically dichlorofluoroethane, classified under HTS 2903.73.01.00 due to its chemical structure with two different halogens.
HCFC-141 (Dichlorofluoroethane Blowing Agent)
Technical grade HCFC-141 serves as an industrial blowing agent for rigid polyurethane foams in insulation panels and refrigeration equipment. As a pure dichlorofluoroethane isomer, it matches the exact chemical specification of HTS 2903.73.01.00 for halogenated acyclic hydrocarbons with multiple halogens.
1,1-Dichloro-1-fluoroethane (R-141b)
R-141b is the refrigerant designation for this dichlorofluoroethane compound, used in precision cleaning of metal parts and as a foam expansion agent. Its classification under HTS 2903.73.01.00 reflects its status as a separate chemically defined organic compound with two different halogens on an acyclic hydrocarbon chain.
HCFC-141b Technical Grade 99.9% Pure
High-purity HCFC-141b (99.9%) is supplied for manufacturing insulated shipping containers and building insulation panels. This separate chemically defined compound qualifies for HTS 2903.73.01.00 as it contains both chlorine and fluorine halogens on an acyclic ethane backbone without additional functional groups.
