U.S. imports of Silico-Manganese Steel Bars and Rods (SITC 67642) totaled $72K in August 2026, imported from 6 countries.
Importers of Silico-Manganese Steel Bars and Rods paid $24K in duties in August 2026, an average duty rate of 33.04% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Silico-Manganese Steel Bars and Rods imports of $72K in August 2026 ran 19% above the year-to-date monthly average of $61K.
Last updated: August 2026 dataSilico-manganese steel derives its properties from a combined silicon and manganese alloying approach, yielding a grade prized for spring applications, agricultural equipment, and structural components requiring high fatigue resistance. Its dedicated SITC classification reflects a chemistry profile distinct from both carbon steel and general alloy steel, and importers must present mill chemistry documentation to support this classification at entry. Like other steel mill products, silico-manganese bar is subject to Section 232 tariffs, making origin and quota status important cost variables for buyers.

Silico-manganese steel is defined by its specific combination of silicon and manganese additions at levels that exceed those of ordinary non-alloy steel. The HTS and SITC schedules carve it out explicitly from general alloy steel NES categories, so the mill test certificate must clearly show both the silicon and manganese percentages to support the classification.
Leaf and coil spring manufacturing for automotive and heavy-vehicle suspensions is the dominant application, as the silicon-manganese combination provides the elastic limit and fatigue life required. Agricultural implement manufacturers and rail equipment producers also specify this grade for components subject to repeated loading.
