7110.11.00.20/Platinum Sponge Catalyst Precursor/China

Platinum Sponge Catalyst Precursor from China

Porous platinum sponge used as a precursor material in the production of heterogeneous catalysts for chemical reactions like hydrogenation. Classified under HTS 7110.11.00.20 as unwrought platinum in sponge form, which is a semi-manufactured state prior to powdering or further processing. It meets the chapter definition of platinum (including alloys with predominant platinum content) in unwrought form.

Import Tips

• Verify platinum content exceeds 2% by weight per Chapter 71 Note 5 to confirm classification as platinum alloy if applicable

• Provide assay certificates documenting metal purity and sponge form to avoid misclassification as powder (requires 90% passing 0.5mm sieve)

• Declare as unwrought material; finished catalyst forms fall under Chapter 38 or 84
