HS-6 · Subheading
290371
Halogenated derivatives of acyclic hydrocarbons containing two or more different halogens; chlorodifluoromethane (HCFC-22)
Heading 2903 — Halogenated derivatives of hydrocarbons
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 290371 when importing or exporting chlorodifluoromethane (HCFC-22), a common refrigerant. This substance is widely used in air conditioning systems and refrigeration applications.
This code specifically applies to halogenated derivatives of acyclic hydrocarbons that contain two or more different halogens. For example, while HS-6 290372 covers similar compounds with different halogen configurations, HS-6 290371 is distinct due to its specific chemical structure and applications.
Chlorodifluoromethane is recognized for its role in reducing ozone depletion compared to other refrigerants, making it a regulated substance in many countries. Understanding its classification is essential for compliance with environmental regulations.
When shipping chlorodifluoromethane, ensure proper labeling and documentation to avoid delays at customs. This includes providing details about the product's use and handling requirements.
