Import Tips

• Provide mill test certificates verifying chemical composition (C <0.20%, Mn >0.9%, Si >0.6%) and diameter ≤1.6mm to avoid reclassification

• Document copper plating thickness and purpose (anti-corrosion/conductivity) as plating must be more than superficial

• Check for welding suitability certification; bulk spools may require weight declarations for duty calculation
