Last updated: April 2026 dataLow-phosphorus nonalloyed pig iron — the primary blast-furnace intermediate used in steelmaking and foundry operations — is subject to Section 232 tariffs as a steel-related article, a trade-remedy measure that significantly affects landed cost calculations for US importers. The phosphorus ceiling of 0.50% by weight is the defining specification threshold: iron at or below this level is preferred for most steel mill applications because higher phosphorus content embrittles finished steel. Foundries and electric arc furnace operators sourcing this grade should factor Section 232 exposure and any applicable exclusion orders into procurement planning. Mill certificates documenting the chemical composition, particularly phosphorus content, are essential for both classification and quality acceptance.

A mill certificate or chemical analysis report from the producing facility, showing the heat or batch composition including phosphorus percentage by weight, is the standard supporting document. CBP may request this at entry to verify classification, and steel buyers routinely require it for quality acceptance. Third-party laboratory analysis can supplement or substitute if the producer certificate is unavailable.
Yes, pig iron falls within the scope of Section 232 steel tariffs. Importers can apply for product exclusions through the Commerce Department's exclusion process if the specific grade or specification is not domestically available in sufficient quantity or quality. Approved exclusions are product- and sometimes requester-specific, so importers should verify whether an existing exclusion covers their particular grade before relying on it.
