Alternative Classifications

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

3812.10Lower: 15% vs 31.5%

If compounded as rubber accelerator preparation

Mixtures with other substances for specific rubber use move to Chapter 38 additives, not pure compounds of Chapter 29

2933.99.97.01Lower: 6.5% vs 31.5%

If primarily classified by quaternary ammonium structure

Heterocyclic nitrogen compounds take precedence in numerical order per Chapter 29 classification rule
