About HS Code 290371
This HS code specifically covers chlorodifluoromethane, commonly known as HCFC-22 or R-22. Historically, R-22 was one of the most widely used refrigerants in residential and commercial air conditioning systems, as well as in various refrigeration applications. It also served as a crucial feedstock for the production of fluoropolymers like PTFE. However, due to its significant ozone-depleting potential (ODP) and global warming potential (GWP), its production and consumption are being phased out globally under the Montreal Protocol. International trade is now heavily restricted, primarily for servicing existing equipment in developing countries or as a feedstock for chemical synthesis, with strict quotas. Importers and exporters are typically chemical manufacturers, refrigerant distributors, and specialized industrial users navigating complex environmental regulations.
Products Under This Code
Chlorodifluoromethane, HCFC-22, R-22 refrigerant, Freon-22, Genetron 22, Suva 22
Real World Examples
DuPont Freon 22, Honeywell Genetron 22, Mexichem R-22, Arkema Forane 22
Common Misclassification
Can be confused with other HCFCs (e.g., 2903.73 for HCFC-141b) or HFCs (e.g., 2903.39 for HFC-134a) if not carefully identified by chemical structure and specific halogen composition.
Products Classified Under 2903.71
Industry
This code belongs to the Chemicals industry.
Trade Overview
China is a major producer and exporter, while developing countries still import for existing equipment, though global trade is declining due to phase-out.
Frequently Asked Questions
What is HS code 290371?
HS code 290371 covers: Halogenated derivatives of acyclic hydrocarbons containing two or more different halogens; chlorodifluoromethane (HCFC-22).
