Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stranded into multi-strand Litz configuration
Stranded steel wire classified as rope/cable regardless of individual wire diameter.
If not zinc coated (other finishes)
Non-zinc coated high-carbon wire uses different circular cross-section heading.
If insulated with enamel after plating
Insulated (magnet) wire moves to Chapter 85 electrical conductors.

Import Tips & Compliance
• Declare as 'individual filaments, not stranded' - stranding changes classification entirely
• High-frequency specs require uniform plating - document coating thickness variation <5%
• Prevent reclassification by proving carbon content via spectrometry certificates
