Importers of Zinc Dust, Powders, and Flakes (Blue Powder) paid $3K in duties in August 2026, an average duty rate of 0.10% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Zinc Dust, Powders, and Flakes (Blue Powder) imports of $3.1M in August 2026 ran 20% below the year-to-date monthly average of $3.9M.
Last updated: August 2026 dataZinc dust — commercially known as 'blue powder' due to its characteristic blue-gray hue — is a critical input for zinc-rich primers, galvanizing compounds, chemical synthesis, and pharmaceutical intermediates. Particle size distribution and purity grade are the primary commercial differentiators: coarser dust grades serve corrosion-protection coatings, while finer, high-purity powders are used in chemical reduction reactions. Flake morphology, produced by milling rather than condensation, yields a higher surface-area product suited to specialty coating formulations.

Condensation-produced zinc dust consists of roughly spherical particles and is the standard form for galvanizing and chemical applications. Milled zinc flake has a lamellar, platelet shape that provides superior barrier properties in corrosion-resistant coatings, making it the preferred form for high-performance zinc-rich primers and automotive underbody coatings.
Zinc dust is classified as a flammable solid under international dangerous goods regulations (UN 1436), so shipments must comply with IMDG, IATA, or DOT hazmat requirements depending on transport mode. Import entries should include proper dangerous goods declarations, and warehouse storage must meet applicable fire-safety standards.
