Import Tips
• Verify the wire meets silico-manganese steel composition limits (carbon ≤0.7%, manganese 0.5-1.9%, silicon 0.6-2.3%) with a mill certificate
• If the wire is heat-treated or surface-conditioned, ensure it remains within Chapter 72 wire definitions
• Check if the wire is considered a 'part of general use' under Section Note 2, which may affect classification
