1.0mm Pure Copper Winding Wire
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-nickel-zinc base alloy (nickel silvers)
Nickel silvers with ≥5% nickel content classify under 7408.22 per subheading note (c), separate from refined copper.
If sold as insulated conductor for retail electronics
Wound or insulated wire for final electrical apparatus use moves to Chapter 85 as insulated conductors.
If copper-tin base alloy (bronze)
Bronzes where tin predominates over other elements (per note b) are classified under 7408.29, not refined copper.

Import Tips & Compliance
• 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
