Dichlorofluoroethane HCFC-141b Cylinder
Dichlorofluoroethane HCFC-141b packaged in 100 lb recovery cylinders is the same chemical compound as in tariff item 2903.73.00. The packaging for transport does not alter its classification, as the product remains a separate chemically defined organic compound. It is used in industrial foam production and solvent recovery systems.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the cylinder contains a blend of HCFC-141b with other substances
A blend would not be a separate chemically defined compound and would fall under the residual subheading for other halogenated derivatives of acyclic hydrocarbons.

Import Tips & Compliance
• Confirm the cylinder is properly labelled and meets Transport Canada regulations for shipping HCFCs
• Since HCFC-141b is an ozone-depleting substance, obtain the necessary import quota or permit from Environment and Climate Change Canada before shipment
• Include the product's purity certificate to prove it is the pure compound, not a mixture
