Silico-Manganese ER70S-6 Welding Wire from China
Round welding wire with diameter 1.5 mm, made from silico-manganese steel containing less than 0.20% carbon, over 0.9% manganese, and more than 0.6% silicon. Specifically formulated for electric arc welding in MIG processes, providing excellent deoxidization and weld puddle stability. Falls under HTS 7229.20.0015 due to its precise chemical composition and suitability for arc welding applications.

Import Tips
• Provide chemical analysis certificates confirming <0.20% C, >0.9% Mn, >0.6% Si content at entry
• Include manufacturer specs verifying suitability for electric arc welding to avoid reclassification
• Ensure wire diameter ≤1.6mm is documented; common pitfall is incorrect measurement leading to higher duty codes
