Rhodium Sponge Unwrought
Porous rhodium sponge obtained from chemical precipitation, remaining in its raw, unwrought state prior to melting or powdering. Classified under HTS 7110.31.00.00 as unwrought rhodium, distinct from powder due to not meeting the 0.5mm sieve test.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ground to powder form (90%+ through 0.5mm sieve)
Subheading note defines powder strictly; finely divided sponge shifts to 7110.41.
If predominantly iridium instead of rhodium
Chapter note 5 classifies PGM alloys by predominant metal weight over others.
If classified as refinery byproduct or concentrate
Unrefined rhodium-bearing materials fall under Chapter 26 precious metal ores/residues.

Import Tips & Compliance
• Provide sieve analysis to prove sponge does not qualify as powder form per subheading note
• Ensure origin certification traces back to refined rhodium meeting precious metal alloy rules
• Avoid common error of declaring as scrap; unwrought sponge must be primary form, not waste

Unwrought Rhodium Bar
A solid bar of pure rhodium in unwrought form, produced directly from refining processes without further shaping or fabrication. It falls under HTS 7110.31.00.00 as unwrought rhodium, which is rhodium not processed into plates, sheets, strips, or other semimanufactured shapes.
Cast Rhodium Ingot Unwrought
Rectangular or trapezoidal ingots of pure rhodium cast from molten metal, intended for remelting without intermediate working. This qualifies as unwrought under HTS 7110.31.00.00, as it lacks deformation like rolling or forging.
