High Purity Refined Copper Billets from China
High purity refined copper billets (99.99% Cu) are cylindrical semi-finished products used primarily for extrusion into rods and wires. They fall under HTS 7403.13.00.00 as unwrought refined copper in billet form, distinct from castings or other shapes. These billets are produced by continuous casting and are essential for electrical wiring and conductors.

Import Tips
• Provide mill test certificates verifying 99.99% copper purity to confirm refined status and avoid reclassification as alloy
• Ensure billets meet ASTM B49 standards for refined copper; improper documentation can lead to higher duties under alloy headings
• Declare exact dimensions and weight accurately, as billets over certain sizes may trigger anti-dumping scrutiny
