U.S. imports of Wire of Silico-Manganese Steel (HS 722920) totaled $8.7M in August 2026, imported from 15 countries.
Importers of Wire of Silico-Manganese Steel paid $4.2M in duties in August 2026, an average duty rate of 48.43% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Wire of Silico-Manganese Steel imports of $8.7M in August 2026 ran 12% above the year-to-date monthly average of $7.7M.
Last updated: August 2026 dataSilico-manganese steel wire — alloyed with both silicon and manganese for enhanced strength and spring characteristics — is widely used in welding consumables, spring wire, and reinforcement applications where standard carbon steel wire lacks sufficient tensile performance. The US schedule breaks this heading into copper-plated welding wire under 1.6 mm (7229200010), arc-welding wire under 1.6 mm (7229200015), and a residual NESOI line (7229200090), with the welding wire lines reflecting the product's major end use in MIG/MAG welding. Vietnam leads US imports under this heading, with Mexico and Italy also significant sources.

Both lines cover round wire under 1.6 mm with less than 0.20% carbon, but 7229200010 is specifically for copper-plated wire, while 7229200015 covers arc-welding wire that is not copper-plated. The copper plating improves electrical conductivity and feedability in MIG welding torches; the presence or absence of that coating, confirmed by the product specification sheet or mill certificate, determines which line applies.
The US has maintained antidumping and countervailing duty orders on steel wire products from various countries, and Vietnam has been subject to orders on certain steel wire categories. Importers should check the current scope of any active orders with CBP and the Department of Commerce, as scope language for alloy wire grades can be technically specific and may or may not capture silico-manganese compositions.
