Classification of semi-finished osmium under HS 7110.49
Semi-finished osmium is classified under HS code 7110.49, which pertains to iridium, osmium, and ruthenium in semi-manufactured forms. Osmium is a member of the platinum group metals (PGM) and is known for its extreme density and hardness. The classification under 7110.49 is determined by the physical state of the metal; it must have undergone some level of processing beyond the unwrought or powder stage but not yet reached the status of a finished article. This includes metallurgical processes such as rolling, drawing, or extruding into specific shapes. Chapter 71 of the Harmonized System covers natural or cultured pearls, precious or semi-precious stones, and precious metals. Within this chapter, heading 7110 specifically targets platinum and other platinum group metals, with subheading 7110.49 covering the semi-manufactured forms of the less common PGMs like osmium.

Codes often confused with 7110.49
Common mistake. Semi-finished osmium is most commonly misclassified under HS code 7110.41. Code 7110.41 is reserved for osmium in its unwrought form or in powder form. The distinction is critical: if the metal has been shaped into a bar, wire, or sheet, it must move from 7110.41 to 7110.49. Another area of confusion is HS code 7115, which covers other articles of precious metal. If the osmium has been fabricated into a specific finished component (like a specialized laboratory instrument tip), it may fall under 7115 rather than the semi-manufactured category of 7110.49.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
