7110.11.00.50/Unwrought Platinum Sponge/China

Unwrought Platinum Sponge from China

Platinum sponge is a porous, unwrought form of platinum produced by chemical precipitation and reduction processes, containing over 99.9% pure platinum by weight. It falls under HTS 7110.11.0050 as unwrought platinum in powder form where 90% or more passes through a 0.5 mm sieve, distinct from bars or ingots. This form is commonly used in catalysis and jewelry fabrication.

Import Tips

• Provide assay certificates verifying platinum purity exceeds 99.5% and powder fineness meets subheading note criteria (90% through 0.5mm sieve)

• Declare exact weight and form (sponge/powder) on commercial invoice; misclassification as semimanufactured risks re-assessment under 7110.19

• Ensure CITES-free sourcing documentation if alloyed traces suggest conflict minerals; common pitfall is undervaluation based on spot price fluctuations
