Import Tips
• Include spectrochemical analysis confirming 0.25-0.6% carbon to prevent disputes over music wire classification
• Document heat treatment specs (tempering details); pitfall is confusion with cold-heading wire
• Ensure no polishing beyond heat treatment; excessive finish may require 'polished' subcategory proof
