More Specific Codes
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 wire is of nickel, not alloyed (at least 99% nickel plus cobalt)
Subheading 7505.11 covers wire of non-alloy nickel, which has different duty treatment.
If the wire is of nickel alloys but cold-formed
Subheading 7505.21 covers cold-formed nickel alloy wire; 7505.22 is for other nickel alloy wire.
If the product is a different form, such as a woven mesh or cloth
Wire products like mesh or gauze fall under heading 7508, not wire of heading 7505.

Import Tips & Compliance
• Ensure the wire meets the subheading note definition of wire (no cross-sectional dimension exceeding 6 mm) to qualify for 7505.22.00
• Provide a mill certificate or lab analysis confirming nickel alloy composition (nickel predominates by weight) to avoid reclassification
• Verify if a Canadian import permit is needed for goods originating from certain countries under trade controls
