0.6mm Ultra-Fine Copper-Plated Silico-Manganese Welding Wire
Ultra-fine 0.6 mm copper-plated round wire made from low-carbon silico-manganese steel, used for precision electric arc welding in thin-sheet applications. The copper coating improves arc stability and conductivity, and the silico-manganese composition (Mn >0.9%, Si >0.6%) qualifies it as other alloy steel wire under tariff item 7229.20.00.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the wire contains alloying elements other than silico-manganese that exceed the thresholds for other alloy steel
Wire of other alloy steel not specifically silico-manganese falls under this residual subheading.
If the wire is coated with flux and sold as welding electrodes
Coated electrodes of base metal for electric arc welding are classified in Chapter 83.

Import Tips & Compliance
• Ensure the wire's chemical composition (C <0.20%, Mn >0.9%, Si >0.6%) is documented in the commercial invoice to support classification under 7229.20.00
• Verify that the copper coating is incidental to the welding function, not a separate product, to avoid reclassification
• Keep mill test certificates available for CBSA verification
