Galvanized High-Carbon Steel Wire for Lock Wire
Round galvanized steel wire with 0.6% or more carbon content and diameter between 1.0-1.5 mm, used for safety wiring in aerospace and automotive assemblies. The zinc coating provides corrosion resistance while the high carbon enables superior tensile strength. Classified under HTS 7217.20.4560 due to its nonalloy composition, specific carbon content, plating, and dimensions.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not plated or coated with zinc
Uncoated high-carbon round wire falls under 7217.10 for nonalloy steel wire without plating.
If alloy steel composition
Alloy steel wire with similar specs moves to Chapter 72 heading 7229, outside nonalloy scope.
If further worked into stranded wire
Stranded or cabled configurations are classified as finished articles in heading 7313.

Import Tips & Compliance
• Certify exact carbon content via mill test certificate as ≥0.6% is required for this subheading
• Measure and document wire diameter precisely (1.0-1.5 mm) to avoid reclassification to adjacent sizes
• Verify zinc coating uniformity through adhesion tests to meet 'plated or coated' criteria
