Import Tips

Provide mill test certificate confirming alloy composition excluding it from high-strength or tool steel notes

Verify wire is not further worked (no plating/coating) to avoid reclassification under 7229.90.10

Declare exact diameter and round cross-section; common pitfall is mismeasurement leading to wrong subheading
