Classification of osmium powder under HS 7110.41
Osmium powder is classified under HS code 7110.41, which specifically covers iridium, osmium, and ruthenium in their unwrought or powder forms. As a member of the platinum group metals (PGMs), osmium is categorized within Chapter 71, which encompasses natural or cultured pearls, precious or semi-precious stones, precious metals, and metals clad with precious metal. The classification is determined by the material's elemental composition and its physical state. Because the product is in a powder form and has not been further worked into a semi-manufactured state such as bars, sheets, or wire, it falls under the 'unwrought or in powder form' subheading. This classification is essential for trade compliance, as precious metal powders are subject to specific environmental and security regulations during international transit.

Codes often confused with 7110.41
Common mistake. Osmium powder is frequently confused with HS code 7110.49. While 7110.41 is reserved for unwrought or powder forms, 7110.49 is used for osmium that has been semi-manufactured, such as rods, tubes, or profiles. Additionally, it may be misclassified under 7106 (silver) or 7108 (gold) by inexperienced importers, though these codes are strictly for their respective metals. Another common error involves 3824.99 for chemical mixtures; however, if the powder is a pure precious metal, Chapter 71 takes precedence over Chapter 38.

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).
