Import Tips & Compliance
• Ensure the wire meets the silico-manganese steel composition (carbon ≤0.7%, manganese 0.5-1.9%, silicon 0.6-2.3%) as per Chapter 72 subheading note 1(e)
• Declare the exact diameter and tensile strength to avoid classification disputes
• Verify if any anti-dumping or countervailing duties apply to steel wire from your country of origin
