Import Tips
• Submit chemical analysis report proving Ni-Cr-Mo content meets alloy steel definition
• Document cold-finishing process (drawing/turning) to distinguish from hot-rolled products
• Check for minimum yield strength if high-strength steel note applies, affecting potential reclassification
