Alternative Classifications

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

2921.49Higher: 16.5% vs 6.5%

If primarily amide-function derivative

If nitrogen-function as amide dominates over heterocycle, earlier heading 2924-2925 takes precedence before 2933 numerical order.

2930.90Higher: 13.7% vs 6.5%

If organo-sulfur impurity present

Heading 2930 for organo-sulfur compounds precedes 2933; if sulfur directly linked to carbon, it classifies there per note.

3824.99.39Higher: 35% vs 6.5%

If crude reaction mixture

Not 'separate chemically defined' per chapter note (a); impure mixtures go to prepared binders or Chapter 38 residuals.

Myclobutanil Technical Grade Fungicide

Myclobutanil is a specific aromatic heterocyclic compound with a 1,2,4-triazole ring, chemically defined as α-Butyl-α-(4-chlorophenyl)-1H-1,2,4-triazole-1-propanenitrile. It falls under HTS 2933.99.06.00 as a pure nitrogen-heterocyclic compound used primarily as an agricultural fungicide. This technical grade is the active ingredient before formulation into end-use products.

Fenbuconazole Pure Active Ingredient

Fenbuconazole, chemically α-[2-(4-Chlorophenyl)ethyl]-α-phenyl-1H-1,2,4-triazole-1-propanenitrile, is a specific nitrogen-heterocyclic fungicide listed explicitly under HTS 2933.99.06.00. This pure form is used as the technical material for synthesizing crop protection formulations. It qualifies due to its aromatic triazole structure and chapter restrictions to chemically defined compounds.

Myclobutanil 95% Technical Powder

This 95% purity Myclobutanil technical powder is the chemically defined α-Butyl-α-(4-chlorophenyl)-1H-1,2,4-triazole-1-propanenitrile with minor stabilizers allowed under chapter note 2(f). It remains classified in HTS 2933.99.06.00 as the additions are solely for preservation/transport. Used as raw material for grape and apple fungicide production.

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.
