Last updated: April 2026 dataLow-phosphorus nonalloy pig iron — the primary blast-furnace feedstock for steelmaking and iron foundries — is subject to Section 232 tariffs, making origin and cost management a central concern for US buyers. Brazil is the dominant supplier under this heading, with Ukraine and Canada also significant sources. The phosphorus ceiling of 0.5% by weight is the defining specification: iron exceeding that threshold shifts to heading 7201.20, and any deliberate alloying element addition moves the product to heading 7201.50.

CBP may require a mill certificate or independent laboratory analysis confirming phosphorus content by weight. Importers should retain the producer's chemical composition certificate with each shipment, as the phosphorus level is the sole criterion separating 7201.10 from 7201.20 and is a common point of CBP inquiry.
Section 232 steel tariffs apply broadly, but country-specific exclusions and quota arrangements have been negotiated with certain trading partners. The applicability and terms for any given origin can change; importers should verify current CBP guidance or consult a licensed customs broker before entry.
