Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the nickel content exceeds 50% and the product is classified as a nickel alloy
AL-6XN has a nickel content of about 24%, which is below the threshold for nickel alloys, but if the composition changes, it could fall under Chapter 75.
If the pipe is not cold-drawn or cold-rolled
This alternative covers seamless tubes of other alloy steel that have not undergone cold-working.

Import Tips & Compliance
• Document the high-nickel alloy composition (approximately 24% nickel) to confirm classification as other alloy steel
• Ensure the cold-drawn manufacturing process is clearly stated on the invoice
• If the pipe is for desalination, verify compliance with Canadian water treatment standards
