Import Tips
• For rectangular-profile wire, ensure the thickness exceeds one-tenth of the width to qualify as wire under Chapter 74; otherwise, it may be classified as strip
• Provide documentation of the copper purity and the exact cross-sectional dimensions
• Verify the wire is in coils and not cut to length
