U.S. imports of unwrought antimonial lead (antimony as principal alloying element) (HS 780191) totaled $6.6M in April 2026, traded with 5 countries.
Importers of Unwrought Antimonial Lead (Antimony as Principal Alloying Element) paid $61K in duties in April 2026 — an effective duty rate of 10% on $611K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataAntimonial lead — unwrought lead in which antimony is the dominant alloying element by weight — is a specialized battery-industry material prized for the hardness and grid-strength it imparts to lead-acid battery plates. Canada and Australia are the leading suppliers to the US market, with the United Kingdom also a notable source. The single tariff line 7801910000 covers this form exclusively; importers must confirm through assay documentation that antimony is indeed the principal other element, since misclassification as refined lead (780110) or a general lead alloy (780199) is a common audit risk. The heading's specificity makes it a useful classification anchor for battery manufacturers managing raw-material sourcing.

CBP interprets 'principal other element' as the alloying element present in the greatest proportion by weight among all elements other than lead. An assay or mill certificate showing antimony content exceeding that of any other individual alloying element supports classification here; if another element (e.g., calcium) predominates, the material falls to 7801999030 as a lead alloy.
Canada is a USMCA partner, and qualifying originating goods may be eligible for preferential tariff treatment under that agreement. Importers must obtain a valid USMCA certification of origin and confirm that the goods meet the applicable rules of origin before claiming the preference.
