SITCSection 6
U.S. imports of ferroalloys, not elsewhere specified (SITC 67159) totaled $64.9M in July 2026, traded with 26 countries.
Importers of Ferroalloys, Not Elsewhere Specified paid $3.9M in duties in July 2026 — an effective duty rate of 9.0% on $43.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataThe residual ferroalloys heading captures commercially significant but less-traded iron-based master alloys — including ferrotungsten, ferromolybdenum, ferrovanadium, ferroniobium, ferrotitanium, and others — that do not have their own dedicated SITC line. Each constituent alloy serves a distinct metallurgical function: ferrovanadium and ferroniobium strengthen high-strength structural steels, ferromolybdenum enhances corrosion resistance in stainless and tool steels, and ferrotungsten is used in high-speed tool steels. Because this heading aggregates chemically diverse products, correct classification requires confirming that the predominant alloying element is not covered by a more specific ferroalloy heading.

Common examples include ferrovanadium, ferroniobium (ferrocolumbium), ferromolybdenum, ferrotungsten, ferrotitanium, ferrophosphorus, and ferrocalcium silicon. Each is classified here because no dedicated SITC heading exists for it. Importers should verify that the specific alloy is not captured by a more specific provision at the HTS 6- or 10-digit level before defaulting to the NES category.
Because the NES heading covers chemically diverse products, a detailed mill certificate specifying the predominant alloying element, its percentage by weight, and all other significant constituents is essential. Customs may challenge classification if the certificate is ambiguous or if the declared element could place the material under a more specific heading. For novel or uncommon alloys, obtaining a CBP binding ruling in advance is advisable to avoid reclassification and potential duty underpayment issues.
