Silica-Supported Copper Dehydrogenation Catalyst
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unsupported or liquid phase
Reaction accelerators without specified support classify under 3815.90.
If as organic synthesis accelerator blend
Multi-component preparations function as chemical mixtures rather than pure catalysts.

Import Tips & Compliance
• 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
