Import Tips
• Submit chemical analysis reports showing 15-17.5% Cr and 3-5% Ni to confirm alloy steel status
• Declare exact cross-section dimensions; bars over certain sizes may require statistical suffix review
• No duty allowance for surface rust per chapter note; ensure proper packaging to prevent entry discoloration
