10 mm Diameter Electrolytic Tough Pitch Copper Wire from Mexico
Electrolytic tough pitch (ETP) copper wire with a 10.2 mm cross-sectional dimension, commonly used in transformer windings and heavy electrical connections. Classified under HTS 7408.11.30.00 due to its refined copper composition and cross-section exceeding 9.5 mm, distinguishing it from finer wires. This high-conductivity wire meets ASTM B5 standards for electrical applications.

Import Tips
• Obtain ASTM B5 or equivalent purity certification to prove refined copper status and avoid alloy misclassification
• Use precise caliper measurements for cross-section; discrepancies can trigger CBP reclassification and penalties
• Declare if oxygen-free to differentiate from standard ETP, though both remain under 7408 for uninsulated wire
