Platinum on Carbon Supported Catalyst from China
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
