Import Tips
• Include chemical analysis certificate matching US Note (h) limits, especially low S/P (<0.03%) and precise Cr content
• Document cold-rolling process to confirm no heat treatment or surface finishing beyond reduction
• Avoid rust/discoloration claims as Chapter 72 note prohibits duty allowances for pre-entry corrosion
