Import Tips
• Include heat analysis certificates proving chromium content >1% to distinguish from carbon steels
• Verify no 'further working' per Chapter notes (no polishing, coating, etc.) to maintain classification
• Check for universal mill plate criteria; narrow widths may require different heading
