Import Tips
• Provide mill test certificates confirming alloy composition (e.g
• Cr, Mo content) to verify classification as alloy steel under chapter note (e),Measure and document exact diameter at thinnest point; exceeding 76 mm shifts to different subheading,Avoid claims for rust/discoloration allowances per chapter note; inspect for further working like polishing
