Products classified under HTS 2933.59.18.00
Thiamethoxam Technical Powder
Thiamethoxam is a neonicotinoid insecticide containing a pyrimidine ring structure, used in agricultural pest control. This technical-grade powder is imported for formulation into end-use pesticides and falls under HTS 2933.59.18.00 as a heterocyclic pyrimidine pesticide compound. It targets sucking insects like aphids and whiteflies on crops.
Imazalil Technical Grade
Imazalil is a systemic imidazole fungicide derived from pyrimidine structures, used post-harvest on citrus and bananas. This technical material is a pure heterocyclic compound imported for pesticide formulation under HTS 2933.59.18.00. It prevents fungal decay during storage and transport.
Fludioxonil Active Ingredient
Fludioxonil is a phenylpyrrole fungicide with pyrimidine ring characteristics, effective against seed and soil-borne diseases. Imported as technical powder for pesticide manufacturing, it classifies under HTS 2933.59.18.00 as a heterocyclic pesticide compound. Commonly used on cereals, vegetables, and turf.
Cyprodinil Technical Material
Cyprodinil is a broad-spectrum fungicide with pyrimidine ring structure, targeting diseases in grapes, apples, and cereals. This technical-grade import falls under HTS 2933.59.18.00 for heterocyclic pesticide compounds used in agricultural formulations. It inhibits fungal methionine biosynthesis.
Pyrimethanil Pure Compound
Pyrimethanil is an anilinopyrimidine fungicide controlling gray mold and other diseases on fruits and vegetables. As a separate chemically defined pyrimidine compound imported for pesticide production, it fits HTS 2933.59.18.00. It works by disrupting fungal amino acid metabolism.
Bupirimate Technical Powder
Bupirimate, a pyrimidine-based fungicide, protects pome fruits and vegetables from powdery mildew. Imported as technical powder for formulation, it qualifies under HTS 2933.59.18.00 as a heterocyclic pesticide with nitrogen-only heteroatoms. It acts systemically through vapor action.
Ethirimol Active Substance
Ethirimol is a pyrimidine fungicide used against powdery mildew in apples and ornamentals. This pure heterocyclic compound imported for pesticide manufacturing falls under HTS 2933.59.18.00 per chapter notes for separate organic compounds. It inhibits fungal RNA biosynthesis.
