Import Tips

Provide continuous casting or rolling process documentation proving semifinished status, avoiding misclassification as 72.08 miscast products

Conduct metallurgical analysis for exact carbon percentage; borderline 0.25% cases require precise lab certification

Watch for rust/discoloration - no duty allowance per Chapter 72 note, but document condition at entry for claim disputes
