HS Code 7406.10 – Copper; powders of non-lamellar structure
HS code 7406.10 is the 6-digit subheading for copper, powders of non-lamellar structure. It is used for electrolytic copper powder, atomized copper powder, spherical copper powder, dendritic copper powder and irregular copper powder.
What HS 7406.10 covers
This category encompasses copper powders with a non-lamellar (non-flake) structure, meaning they typically have irregular, spherical, or dendritic shapes. These powders are produced through methods like atomization or electrolysis and are highly valued for their specific surface area and flow characteristics. They are critical inputs for advanced manufacturing processes such as powder metallurgy, additive manufacturing (3D printing), and the production of electrical contacts, friction materials, and catalysts. Importers and exporters are often found in countries with strong high-tech manufacturing and electronics industries, including Germany, Japan, and the USA. The trade in these specialized powders reflects the global push towards more efficient and complex material solutions in various engineering applications.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
