Import Tips
• Include ASTM A228 compliance certs showing tensile strength from heat treatment to support classification
• Watch for 'further worked' treatments like coating that would exclude from 7217.10 per Chapter notes
• Batch-test for uniformity; non-uniform carbon content risks audit and reclassification
