Import Tips
• Provide detailed chemical analysis from MTR confirming Cr <15% and martensitic structure to distinguish from austenitic grades
• Document cold-rolling process only (no annealing/polishing) and measure uncoiled width to ensure >600 mm compliance
• Watch for rust/discoloration allowances—none permitted under Chapter 72 notes, so inspect entries carefully
