Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If diagnostic reagents kit component
Lab reagents for analysis may shift to Chapter 38 if prepared for specific diagnostic use, excluding pure Chapter 29 compounds.
If oxygen hetero-atom dominates classification
Heterocyclic with oxygen (not nitrogen only) would go to 2932; numerical order prioritizes correct hetero-atom heading.
If personal effects or research samples
Non-dutiable under personal baggage if for individual research use, bypassing Chapter 29 entirely.

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.
Fenbuconazole Process Intermediate
Fenbuconazole as a chemical intermediate in multi-step synthesis, specifically the named 1H-1,2,4-triazole-1-propanenitrile under HTS 2933.99.06.00. This pure compound is imported for final formulation stages in fungicide manufacturing. Chapter notes confirm classification for chemically defined heterocyclics.
