Silica-Supported Copper Dehydrogenation Catalyst from Japan
Copper oxide on silica gel accelerates dehydrogenation of alcohols to aldehydes in fine chemical production. This 'other' supported catalyst fits HTS 3815.19.00.00 as it doesn't meet precious or specific base metal criteria.

Import Tips
• Submit SEM/EDX analysis proving metal dispersion on support matrix for proper classification
• EPA TSCA registration required for new catalyst formulations entering US commerce
• Avoid common pitfall of declaring as 'catalyst precursor' which shifts to Chapter 28
