Silico-Manganese Steel Welding Wire
A high-strength welding wire made from silico-manganese steel, used in arc welding applications for structural steel fabrication. It falls under HTS 7229.20.00 as it is wire of silico-manganese alloy steel, which contains silicon and manganese as key alloying elements. The wire is typically drawn to precise diameters for consistent weld bead formation.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not of silico-manganese steel
Wire of other high-speed or tool steels falls under different subheadings in 7228 if lacking specific silico-manganese alloy composition.
If stranded or cable form
Stranded wire, rope, or cables of iron or steel are classified in Chapter 73 regardless of alloy composition.
If coated or further worked
Further worked wire (coated, polished, etc.) moves to 7229.90 per Chapter 72 notes on surface treatments.
