Platinum on Carbon Supported Catalyst from Japan

A high-surface-area activated carbon support impregnated with platinum nanoparticles, used primarily as a hydrogenation catalyst in organic synthesis. It falls under HTS 3815.12.0010 because the platinum group metal acts as the active substance on a solid support. Common in pharmaceutical and fine chemical production for reducing functional groups.

Import Tips

Obtain EPA TSCA certification and provide detailed composition disclosing platinum content to avoid reclassification

Include safety data sheets (SDS) and ensure packaging prevents catalyst deactivation during transport

Verify precious metal content declarations for CBP valuation; common pitfall is undervaluation of platinum
