Bare Copper Grounding Stranded Wire 4 AWG
4 AWG bare stranded copper wire designed for electrical grounding systems in buildings and equipment. It is classified under HTS 7413.00.10.00 because it is stranded copper wire, electrically uninsulated, without fittings, and supplied as raw material. Commonly used where high conductivity is needed without insulation.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-nickel base alloys
Copper-nickel alloys (nickel predominant, zinc <=1%) are under 7407.12 per note (d).
If chemically treated for corrosion resistance
Surface-treated copper products may shift to chemical compounds or other headings if not purely metallic.
If shaped into nails, tacks, or screws
Further fabrication into fasteners reclassifies to 7415.21.

Import Tips & Compliance
• Label shipments clearly as 'bare grounding wire, not insulated' to distinguish from Chapter 85 products
• Comply with ASTM B8 standards documentation for strand lay and construction verification
• Monitor for oxidation; tarnished wire still qualifies if not treated as insulated
