Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

3815.90.50Higher: 40% vs 35%

If unsupported or liquid phase

Reaction accelerators without specified support classify under 3815.90.

3824.99.39Same rate: 35%

If as organic synthesis accelerator blend

Multi-component preparations function as chemical mixtures rather than pure catalysts.
