U.S. imports of Copper Powders of Non-Lamellar Structure (HS 740610) totaled $4.9M in August 2026, imported from 17 countries.
Importers of Copper Powders of Non-Lamellar Structure paid $2.4M in duties in August 2026, an average duty rate of 49.45% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Copper Powders of Non-Lamellar Structure imports of $4.9M in August 2026 ran 13% above the year-to-date monthly average of $4.4M.
Last updated: August 2026 dataNon-lamellar copper powder—produced by atomization or electrolytic deposition into roughly spherical or irregular particles rather than flat flakes—is a key input for powder metallurgy, metal injection molding, and additive manufacturing applications. The entire heading resolves to a single 10-digit line (7406100000), so classification is straightforward, but distinguishing non-lamellar from lamellar (flake) powder at entry is essential because the two headings carry different commercial uses and, in some cases, different duty treatment. The United Kingdom and Germany are the leading US suppliers, consistent with Europe's strong position in engineered metal powders for industrial manufacturing.

Non-lamellar powders have particles that are roughly equiaxed—spherical, nodular, or irregular in shape—as opposed to lamellar (flake) powders, which are flat and plate-like. The production method is a reliable indicator: atomization and electrolytic processes typically yield non-lamellar particles, while milling or stamping of thin copper sheet produces flakes classified under 7406200000.
Powder metallurgy parts manufacturing (sintered bearings, bushings, and structural components), metal injection molding, electrical contact materials, and increasingly binder-jet additive manufacturing are the primary end uses. The powder's particle morphology and size distribution are specified by buyers, so certificates of analysis documenting these parameters typically accompany commercial shipments.
