Classification of rhodium powder under HS 7110.31
Rhodium powder is classified under HS code 7110.31. Rhodium is a rare, silvery-white, hard, and chemically inert transition metal and a member of the platinum group. 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 addresses platinum, palladium, rhodium, iridium, osmium, and ruthenium. The subheading 7110.31 is designated for rhodium in its primary, unwrought forms or specifically as a powder. The term powder refers to products of which at least 90% by weight passes through a sieve with a mesh aperture of 0.5 mm. This classification is critical because rhodium is often traded in powder form (often called rhodium sponge) for industrial applications, such as the production of catalytic converters or as an alloying agent. The distinction between unwrought and semi-manufactured is the primary factor in choosing between 7110.31 and 7110.39. Unwrought rhodium includes ingots, blocks, and grains, while powder is specifically called out in the .31 subheading. If the rhodium has been worked into sheets, wire, or tubes, it is considered semi-manufactured. Because rhodium is one of the most expensive precious metals, accurate classification is essential for duty calculation and for monitoring the trade of strategic minerals.

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).
