Import Tips
• Confirm the product is specifically HCFC-141 (1,1-dichloro-1-fluoroethane) and not a different isomer, as the tariff item only covers this compound
• Since HCFC-141 is an ozone-depleting substance, secure an import quota from Environment and Climate Change Canada
• Provide a technical data sheet to customs to verify the product's identity and purity
