Tebuconazole
Tebuconazole is a systemic triazole fungicide with a 1,2,4-triazole heterocyclic ring used in agriculture for cereal crops and turf protection against fungal diseases. Classified under HTS 2934.99.18.00 as an aromatic or modified aromatic heterocyclic pesticide, it contains the characteristic nitrogen heterocyclic structure defined in Chapter 29 notes. The pure technical grade (>95% purity) qualifies as a separate chemically defined compound.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when imported in fungicidal formulations or wettable powders
Pesticide products containing fungicide isomers or mixtures classify in Chapter 38 headings for goods put up for retail or agricultural use.
If for non-pesticidal triazole intermediates used in synthesis
Triazole compounds without pesticide designation fall under other azines or triazines in heading 2933.
If emphasis on imide or amide function over heterocyclic pesticide nature
Chapter notes prioritize classification by latest numerical heading, but primary function may shift to carboximide compounds.

Import Tips & Compliance
• EPA registration number must appear on commercial invoice; unregistered imports face seizure
• Provide HPLC purity analysis certificate; impurities >2% may trigger reclassification
• Declare as 'technical grade pesticide active ingredient' to avoid bulk chemical treatment under 28xx
