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
