Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the argon is mixed with other rare gases
Mixed rare gases are classified under other rare gases rather than pure argon.

Import Tips & Compliance
• 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
