Import Tips
• Provide mill test certificate confirming alloy composition (Cr, Mo content) to verify classification as alloy steel
• Ensure accurate dimensional measurement documentation; cross-section must be certified under 76 mm
• Avoid common pitfall of misclassifying as hot-rolled (7228.30); cold-forming process must be documented
