Import Tips

Certify no 'further worked' treatments like phosphatizing per US notes; clean mill finish only

Batch test for alloy content—spot checks prevent misclassification to stainless (Ch 72) or carbon steel

Document cold-rolling reduction ratio if audited; distinguishes from hot-rolled under 7225
