U.S. imports of zinc dust (HS 790310) totaled $67K in June 2026, traded with 7 countries.
Importers of Zinc Dust paid $7K in duties in June 2026 — an effective duty rate of 10% on $67K in dutiable value, based on actual customs collections rather than the published tariff schedule. Zinc Dust imports of $67K in June 2026 ran 13% below the year-to-date monthly average of $77K.
Zinc dust — a fine, spherical powder produced by condensation of zinc vapor — is a critical input for corrosion-inhibiting primers, chemical synthesis (including pharmaceutical intermediates), and battery electrode manufacturing. Belgium and Norway are the leading US suppliers, reflecting Europe's concentration of specialized zinc dust production capacity. Because particle size and surface area directly affect reactivity and end-use performance, importers should ensure technical data sheets accompany shipments to support both classification and buyer specification compliance.

Zinc dust (7903100000) consists of fine spherical particles produced by vapor condensation and is characterized by a high surface area and reactivity. Zinc powder, classified under 790390, is typically produced by mechanical attrition and has a coarser, more irregular morphology. The production method and particle characteristics documented in the supplier's technical data sheet are the key classification evidence.
Zinc dust is classified as a flammable solid under DOT and IMDG regulations, requiring proper hazardous materials labeling and documentation during transport. Importers should also confirm that Safety Data Sheets (SDS) are current and that the material meets any applicable OSHA or EPA reporting thresholds for the intended end use.
