Fenbuconazole Stabilized Crystals

Fenbuconazole stabilized crystals contain the named propanenitrile triazole with anticaking agents per chapter note 2(f), maintaining classification in HTS 2933.99.06.00. This form prevents clumping during transport for formulation into seed treatments. Its aromatic nitrogen-heterocycle defines the tariff placement.

Alternative Classifications

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

2933.99.97.01Same rate: 6.5%

If purity drops below technical grade or unnamed isomer

Specific subheading 2933.99.06.00 only for listed compounds; other 'Other' nitrogen-heterocyclics go to basket provision.

2910.90Higher: 14.8% vs 6.5%

If ester derivative for synthesis

Chapter note 3(A) classifies esters with the later-numbered acid-function compound, potentially shifting from pure heterocycle.

3808.93.50Higher: 40% vs 6.5%

If for water-diluted standard strength per note 2(d)

Note 2(d) allows water solutions, but if exceeding safety/transport limits, it becomes a pesticidal preparation in 3808.
