Products classified under HTS 2934.99.18.00
Imazalil
Imazalil is an aromatic heterocyclic imidazole fungicide used primarily as a post-harvest treatment for citrus fruits and vegetables to prevent mold growth. It falls under HTS 2934.99.18.00 as an aromatic heterocyclic compound specifically classified as a pesticide, meeting the chapter's criteria for chemically defined organic compounds with nitrogen-containing rings. Its structure includes a modified aromatic imidazole ring directly linked to functional groups.
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.
Propiconazole
Propiconazole, a conazole-class fungicide featuring a 1,2,4-triazole ring, protects crops like rice, turf, and ornamentals from fungal pathogens. It qualifies for HTS 2934.99.18.00 as an 'other' aromatic heterocyclic pesticide, distinct from nucleosides, with its modified aromatic structure meeting Chapter 29's chemical definition requirements. Technical grade material is imported for formulation into end-use products.
Fludioxonil
Fludioxonil is a phenylpyrrole fungicide with a modified aromatic heterocyclic structure used as seed treatment and post-harvest protectant. Under HTS 2934.99.18.00, it classifies as an 'other' aromatic heterocyclic pesticide, containing nitrogen and oxygen in ring structures per Chapter 29 definitions, excluding epoxides or cyclic anhydrides noted. Pure active ingredient supports its chemical compound status.
Cyprodinil
Cyprodinil, a pyrimidinamine fungicide with an aromatic pyrimidine heterocyclic ring, controls diseases in grapes, apples, and cereals. HTS 2934.99.18.00 covers it as an 'other' aromatic heterocyclic pesticide, aligning with Chapter 29's rules for chemically defined compounds and last-in-numerical-order classification over earlier amine headings. Technical material purity exceeds 97%.
Fenbuconazole
Fenbuconazole is a triazole fungicide featuring a 1H-1,2,4-triazole ring used against powdery mildew in fruits and vegetables. It fits HTS 2934.99.18.00 as an aromatic heterocyclic pesticide 'other,' satisfying Chapter 29's exclusion of sulfonated derivatives and inclusion of chemically defined salts. Imported as beige powder technical concentrate.
Myclobutanil
Myclobutanil, a triazole fungicide with modified aromatic 1,2,4-triazole, prevents fungal diseases in grapes, turf, and almonds. Classified in HTS 2934.99.18.00 as 'other' aromatic heterocyclic pesticides, it meets criteria for separate chemically defined compounds without excluded colorants or enzymes. White crystalline technical grade imported for downstream formulation.
Benzimidazole Carbendazim
Carbendazim is a benzimidazole fungicide derived from 2-benzimidazolecarbamic acid, used systemically against fungal diseases in crops. HTS 2934.99.18.00 includes it as an aromatic heterocyclic pesticide 'other,' with its fused benzene-imidazole ring system qualifying as chemically defined per Chapter notes excluding metal-coordination compounds. Technical powder >98% purity.
Prothioconazole
Prothioconazole features a triazolemethylthio ring system as a broad-spectrum triazole fungicide for cereals and soybeans. It falls under HTS 2934.99.18.00 as an 'other' aromatic heterocyclic pesticide, containing organo-sulfur directly linked to carbon per Chapter 29 note on heading 2930 exclusions. Imported as off-white technical solid.
Difenoconazole
Difenoconazole is a diphenyl triazole fungicide protecting fruits, vegetables, and turf from fungal infections via its 1,2,4-triazole structure. HTS 2934.99.18.00 designates it as an aromatic heterocyclic pesticide 'other,' compliant with Chapter 29's numerical classification rule over earlier halogenated derivatives. Technical grade imported as yellowish powder.
