Import Tips
• Provide mill test certificates confirming alloy composition (e.g
• Cr, Mo levels) to verify against chapter note (e) tool steel exclusions
• Declare exact cold-forming process; mislabeling as hot-rolled shifts to 7228.30 headings
• Check for 'further worked' treatments like coating, which move to 7228.70; document surface condition
