Products classified under HTS 2932.99.21.00
Carbofuran
Carbofuran is an aromatic heterocyclic carbamate pesticide containing oxygen hetero-atoms, used primarily as a systemic insecticide for soil and foliar applications on crops like corn and soybeans. It falls under HTS 2932.99.21.00 as an aromatic pesticide with oxygen-containing heterocyclic structure. Technical grade carbofuran is imported as the active ingredient for pesticide formulation.
Oxamyl Technical
Oxamyl is a systemic carbamate insecticide and nematicide with an aromatic oxime ether structure containing oxygen hetero-atoms, used on vegetables, tobacco, and cotton. Classified under HTS 2932.99.21.00 due to its aromatic heterocyclic oxygen-containing pesticide chemistry. Imported as 95%+ technical concentrate for further formulation.
Methomyl Technical Powder
Methomyl is an oxime carbamate insecticide with oxygen-containing heterocyclic structure, used for foliar control of chewing and sucking insects on various crops. Falls under HTS 2932.99.21.00 as aromatic pesticide derived from methylcarbamic acid. Technical powder imported at 98% purity for Lannate formulations.
Thiodicarb Technical
Thiodicarb is an aromatic heterocyclic insecticide with oxygen and sulfur hetero-atoms, metabolized to methomyl in plants, used on cotton and vegetables. Although containing sulfur, classified under HTS 2932.99.21.00 as primary oxygen-heterocycle pesticide per chapter note precedence. 95% technical grade imported for Larvin insecticide production.
Oxytetracycline Base
Oxytetracycline is a broad-spectrum antibiotic technically classified as aromatic oxygen-heterocycle when used as veterinary pesticide against bacterial diseases in aquaculture and livestock. Falls under HTS 2932.99.21.00 for pesticide applications despite pharmaceutical uses. Imported as 95%+ technical powder for fish feed medication.
Benzoxazinone Herbicide Intermediate
Benzoxazinone derivatives serve as key intermediates for synthesizing aromatic oxygen-heterocyclic herbicides targeting weed ACCase enzymes in cereals. Classified under HTS 2932.99.21.00 as pesticide technical material with oxygen-only heterocyclic structure. High-purity intermediates imported for final pesticide synthesis.
Fenoxaprop-p-ethyl Technical
Fenoxaprop-p-ethyl is an aryloxyphenoxypropionate herbicide with oxygen-heterocyclic structure, used for post-emergence grass control in wheat and soybeans. The ethyl ester maintains aromatic oxygen-heterocycle classification under HTS 2932.99.21.00 as pesticide active ingredient. 95% technical liquid imported for Acrobat formulations.
