Rhodium Sponge
Porous rhodium sponge, an unwrought intermediate form produced during refining, used for further processing into powder or bars. Falls under HTS 7110.39.00.00 as 'other' rhodium not in powder or specific semimanufactured shapes. Excludes alloys dominated by other platinum group metals.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If 90%+ passes 0.5mm sieve
Subheading note defines 'powder form' strictly; fine sponge powder classifies under 7110.31.
If in intermediate ore residues
Precious metal residues from smelting go to Chapter 26, not refined unwrought forms.
If alloy with >2% platinum
Chapter Note 5 prioritizes platinum in mixed PGM alloys, shifting from rhodium heading.

Import Tips & Compliance
• Include metallurgical certificates showing rhodium predominance over other PGMs like iridium or palladium
• Avoid 'semimanufactured' descriptors in docs; classify as unwrought sponge to stay in 7110.39
• Check for powder content; if >90% <0.5mm, it may shift to powder subheading 7110.31
