Import Tips
• PH grade requires detailed alloy cert (17% Cr, 4% Ni, Cu precipitation); generic 400-series docs insufficient
• Note condition (H900, H1150) on entry docs doesn't affect HTS but important for end-use compliance
• Coils must arrive rust-free; no duty allowance for Chapter 72 discoloration per note
