High-Carbon Zinc-Coated Litz Wire Base 0.6mm from Mexico
Individual galvanized filaments of ≥0.6% carbon steel, 0.6mm diameter, used as base wire for stranded Litz wire in high-frequency transformers. Classified HTS 7217.20.45.30 for single round wire specs before stranding. Zinc coating prevents inter-filament corrosion during electromagnetic applications.

Import Tips
• 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
