Rhodium Powder (99.9% Pure)
High-purity rhodium powder where 90% or more passes through a 0.5 mm sieve, used in catalysts and plating. Classified under HTS 7110.39.00.00 as rhodium in powder form, per subheading note for Chapter 71. Unwrought form suitable for industrial applications like chemical processing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloyed with >2% platinum by weight
Per Chapter Note 5(a), alloys with 2%+ platinum classify as platinum alloys under 7110.19, not pure rhodium.
If chemically defined as rhodium compounds
Rhodium salts or compounds fall under Chapter 28 chemicals, not Chapter 71 precious metals.
If in sintered forms or sheets >0.25mm thick
Semimanufactured rhodium (e.g., foil, wire) moves to other rhodium subheadings excluding powder.

Import Tips & Compliance
• Verify powder fineness with sieve test certification to meet subheading 7110 definition (90% through 0.5mm mesh)
• Provide assay reports confirming rhodium purity >2% to avoid reclassification under base metals
• Declare as unwrought; avoid packaging suggesting semimanufactured forms to prevent misclassification
