SITCSection 6
U.S. imports of copper powders and flakes (SITC 68262) totaled $4.7M in April 2026, traded with 15 countries.
Importers of Copper Powders and Flakes paid $2.2M in duties in April 2026 — an effective duty rate of 49% on $4.5M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataProduced by atomization, electrolysis, or mechanical reduction, copper powders and flakes serve as inputs for powder metallurgy parts, conductive inks and pastes, diamond tooling, and chemical catalysts — each application demanding distinct particle size distribution, morphology, and surface chemistry. Particle shape (spherical atomized vs. dendritic electrolytic vs. lamellar flake) is the primary specification variable that determines suitability for a given end use and can also influence classification at more detailed tariff levels. The electronics and additive manufacturing sectors have driven growing demand for ultra-fine and high-purity copper powder, making this a technically specialized import category. Importers should document particle size (D50, D90) and apparent density on commercial invoices to support classification and buyer acceptance testing.

Spherical atomized powder flows freely and is preferred for metal injection molding and additive manufacturing; dendritic electrolytic powder has high surface area and is favored for powder metallurgy self-lubricating bearings and friction materials; lamellar flake is used in conductive coatings and inks. Specifying morphology, particle size distribution (D10/D50/D90), and apparent density in the purchase contract is essential to avoid receiving a technically incompatible product.
Fine copper powder can be combustible and may be subject to DOT hazardous materials regulations for transport (UN 3089, metal powder, flammable). Importers should confirm the correct hazmat classification with their freight forwarder and ensure that safety data sheets (SDS) accompany the shipment. Particle size and moisture content affect combustibility risk and should be reviewed when evaluating storage and handling requirements.
