HS Code for HCFC-22

HCFC-22, also known as chlorodifluoromethane, is classified under HS code 2903.71. This classification is derived from its chemical structure as a halogenated derivative of methane. As a single, chemically defined organic compound, it is placed within Chapter 29 (Organic Chemicals). Heading 2903 covers halogenated derivatives of acyclic hydrocarbons, and the specific subheading 2903.71 is dedicated exclusively to chlorodifluoromethane. This substance is one of the most common hydrochlorofluorocarbons used globally in air conditioning and refrigeration systems. The classification is critical because HCFC-22 is an ozone-depleting substance subject to phase-out schedules under the Montreal Protocol. The unique HS code allows for precise tracking of its international trade, ensuring that countries adhere to their consumption and production caps.

Products Included

• Pure chlorodifluoromethane gas
• HCFC-22 refrigerant (R-22)
• HCFC-22 used as a chemical feedstock
• Liquid HCFC-22 in pressurized cylinders

Common Misclassification

HCFC-22 is often misclassified under HS code 3827.31 or 3827.39, which are intended for mixtures containing hydrochlorofluorocarbons. If the product is pure R-22, it must stay in Chapter 29. It is also sometimes confused with HFC-23 (trifluoromethane), which is classified under 2903.39. Importers must distinguish between pure HCFC-22 and refrigerant blends like R-407C or R-410A, which contain HFCs and are classified in Chapter 38.

FAQ

What is the HS code for HCFC-22?

The HS code for pure HCFC-22 (chlorodifluoromethane) is 2903.71.

Can HCFC-22 be classified under Chapter 38?

Only if it is part of a mixture. Pure HCFC-22 is always classified under 2903.71 as a chemically defined compound.
