Import Tips

Provide mill test certificates verifying copper purity (99.99%+ for OF copper) and refined status to avoid reclassification as unwrought

Measure cross-section precisely; dimensions over 35mm shift to 7407.10.15, common pitfall for larger profiles

Ensure EN or ASTM specs are documented for electrical conductivity claims during customs valuation
