Import Tips & Compliance
• Ensure the wire's composition meets the high-speed steel definition in subheading note 1(d) of Chapter 72, with at least two of molybdenum, tungsten, and vanadium combined at 7% or more by weight
• Provide a mill certificate or certified analysis to the CBSA to support classification
• Verify the wire is in coil form and not further worked beyond drawing to avoid reclassification
