Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is chlorodifluoromethane (HCFC-22)
HCFC-22 is a different halogenated acyclic hydrocarbon with its own tariff item.
If the product is a hydrobromofluorocarbon (HBFC)
HBFCs are classified separately under the halogenated derivatives of acyclic hydrocarbons.
If the product is a mixture or preparation, not a pure compound
Mixtures not meeting Chapter 29 purity criteria fall under chemical products and preparations.

Import Tips & Compliance
• Verify that the product is pure monochlorotetrafluoroethane and not mixed with other substances, as Chapter 29 covers only separate chemically defined compounds
• Check if the HCFC-124 requires an import permit under Canada's Ozone-Depleting Substances Regulations before shipping
• Declare the correct end-use (foam blowing) to avoid misclassification as a refrigerant
