U.S. imports of lead monoxide (litharge & massicot) (HS 282410) totaled $324K in June 2026, traded with 5 countries.
Importers of Lead Monoxide (Litharge & Massicot) paid $14K in duties in June 2026 — an effective duty rate of 13% on $108K in dutiable value, based on actual customs collections rather than the published tariff schedule. Lead Monoxide (Litharge & Massicot) imports of $324K in June 2026 ran 105% above the year-to-date monthly average of $158K.
Last updated: June 2026 dataLead monoxide (PbO) — traded as litharge (the red orthorhombic form) or massicot (the yellow tetragonal form) — is a primary raw material for lead-acid battery plate manufacturing, glass formulation, and ceramic glazes. South Africa and Brazil lead US imports under tariff line 2824100000, with Australia also a notable source. Because lead compounds are regulated hazardous substances under EPA and OSHA frameworks, importers must maintain safety data sheets and comply with hazardous materials shipping regulations; certain downstream uses in consumer products are also subject to CPSC lead-content restrictions. The specific crystal form (litharge vs. massicot) affects reactivity in battery paste mixing and should be confirmed in supplier specifications.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Lead monoxide is a hazardous substance subject to DOT hazardous materials transport regulations (49 CFR) and EPA Toxic Substances Control Act (TSCA) import certification requirements. Importers must certify at entry that the shipment complies with TSCA or is not subject to it. Additionally, OSHA's lead standard applies to worker exposure in downstream processing, and any use in consumer products must comply with CPSC lead-content limits.
Litharge (α-PbO, red form) is the commercially preferred grade for lead-acid battery plate paste because of its higher reactivity with sulfuric acid during the curing process. Massicot (β-PbO, yellow form) is metastable and less commonly specified for battery use, though it may appear in glass and ceramic applications. Battery manufacturers typically specify litharge by crystal form and surface area in procurement contracts to ensure consistent paste mixing performance.
