1.0mm Pure Copper Winding Wire from Japan
Unalloyed refined copper wire, 1mm diameter, coated with thin polyurethane insulation for transformer windings. Falls under HTS 7408.19.0030 as refined copper wire ≤3mm cross-section, distinguished from alloy wires by its high purity electrolytic copper base. Commonly used in power distribution equipment.

Import Tips
• Include annealing specifications; soft-drawn wire must specify temper to avoid valuation disputes
• Provide dimensional tolerance certificates (±0.01mm typical) to prevent reclassification
• Label as 'refined copper' explicitly; alloy trace elements over limits trigger Chapter 74 subheading shifts
