Basic heading 67123 · $4K of $26.7B
Spiegeleisen — a manganese- and carbon-rich iron alloy historically used as a deoxidizer and manganese addition in Bessemer and open-hearth steelmaking — shares this heading with alloy pig iron, both supplied in primary forms such as pigs, blocks, or broken pieces. The commercial relevance of spiegeleisen has diminished with modern steelmaking practices, but alloy pig iron containing titanium, vanadium, or other alloying elements remains a specialized input for certain foundry and specialty steel applications. Section 232 tariffs apply to these iron-based primary forms as steel-related articles. Importers should document the alloy composition fully on mill certificates, as the presence and percentage of alloying elements determine both classification and the metallurgical suitability for downstream processing.

Spiegeleisen is an iron-manganese-carbon alloy with a relatively lower manganese content (typically 15–30%) compared to standard ferromanganese (which runs 70–80% manganese). For classification, spiegeleisen is grouped with alloy pig iron as a primary iron product, while ferromanganese is classified as a ferroalloy. The distinction matters because the two product families sit in different tariff headings with potentially different duty treatment.
Yes, alloy pig iron falls within the scope of Section 232 steel tariffs because it is an iron-based primary form used in steelmaking and foundry production. Importers should check whether any product-specific exclusions have been granted for the particular alloy composition they are sourcing, as exclusion availability varies by grade and origin.
