Alternative Classifications

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

2934.99.12.00Same rate: 6.5%

If containing morpholine functional group

Morpholines have specific pesticide subheading within 2934; triazoles default to 'other'.

3808.59.10.00Higher: 16.5% vs 6.5%

If seed treatment formulations

Specific goods put up for seed treatment classify under 3808.59 rather than pure AI.

2914.79Higher: 14% vs 6.5%

If ketone function predominates over heterocyclic identity

Chapter notes restrict oxygen functions; pesticide heterocycle takes precedence numerically.
