Import Tips
• Ensure the gas is invoiced as pure argon (CAS 7440-37-1) and not as a mixture, as mixtures may fall under other headings
• Verify the cylinder's transport documentation complies with Transport Canada regulations for dangerous goods
• If the argon is in a cylinder that is not refillable, confirm whether the cylinder itself is separately classifiable
