Import Tips

Provide mill test certificates verifying refined copper purity (99.99%+ Cu) and rectangular cross-section dimensions to avoid reclassification

Declare exact cross-sectional shape as rectangular (not square or hollow) with precise measurements; common pitfall is mismeasuring profiles

Ensure compliance with ASTM B187 standards for documentation to prevent customs holds on high-value copper imports
