Electrolytic Tough Pitch Copper Billets from Canada
Electrolytic tough pitch (ETP) copper billets are refined copper (99.9% Cu with controlled oxygen) cast into billet form for wire rod production. Classified under HTS 7403.13.00.00 as unwrought refined copper billets, they are key for high-conductivity applications like power cables. Produced via electrolytic refining for optimal electrical properties.

Import Tips
• Include electrolytic refining process documentation to distinguish from fire-refined copper, preventing misclassification
• Verify compliance with electrical conductivity standards (IACS minimum 100%) via lab reports for customs clearance
• Watch for Section 232 tariffs on copper; apply for exclusions if billets are for defense-critical applications
