0.8mm Copper-Coated ER70Si Silico-Manganese Welding Wire from China
Precision 0.8 mm round wire of ER70Si-grade silico-manganese steel (C <0.20%, Mn >0.9%, Si >0.6%), copper plated for superior arc stability in gas-shielded electric arc welding. Used in automotive and fabrication industries for clean welds. HTS 7229.20.0010 applies due to its specialized low-carbon alloy, small diameter, and copper coating.

Import Tips
• Submit chemical analysis reports from accredited labs to prove compliance with low carbon and high Mn/Si thresholds
• Label spools clearly with HTS code, alloy specs, and 'for welding use only' to aid customs inspection
• Beware of rust/discoloration claims; Chapter 72 notes deny duty reductions for pre-entry corrosion on steel wire
