Products classified under HTS 2934.99.15.00
Glyphosate (N-(phosphonomethyl)glycine)
Glyphosate is a broad-spectrum systemic herbicide used to kill weeds, especially annual broadleaf weeds and grasses that compete with crops. It falls under HTS 2934.99.1500 as an aromatic heterocyclic herbicide compound. Its active ingredient structure contains the necessary heterocyclic rings qualifying it for this classification.
2,4-Dichlorophenoxyacetic Acid (2,4-D)
2,4-D is a synthetic auxin herbicide effective against broadleaf weeds in cereal crops and turfgrass. This aromatic compound with ether linkage qualifies as a herbicide under HTS 2934.99.1500 due to its heterocyclic characteristics. It's widely used in agriculture and right-of-way maintenance.
Dicamba (3,6-dichloro-2-methoxybenzoic acid)
Dicamba is a benzoic acid herbicide used for broadleaf weed control in soybeans and cotton. Its aromatic structure with methoxy group qualifies it under HTS 2934.99.1500 as an aromatic heterocyclic herbicide. Often used in combination with glyphosate for resistant weeds.
Metsulfuron-methyl
Metsulfuron-methyl is a sulfonylurea herbicide for broadleaf weeds and grasses in cereals. This aromatic heterocyclic compound falls under HTS 2934.99.1500 due to its complex heterocyclic ring structure essential for herbicidal activity. Selective action makes it valuable for no-till farming.
Imazapyr
Imazapyr is an imidazolinone herbicide for non-selective weed control in industrial sites. Its bicyclic heterocyclic structure qualifies classification under HTS 2934.99.1500 as an aromatic herbicide. Used for aquatic weed control and right-of-way vegetation management.
Triclopyr
Triclopyr is a pyridine carboxylic acid herbicide for woody plants and broadleaf weeds. The pyridine ring structure makes it an aromatic heterocyclic herbicide under HTS 2934.99.1500. Commonly used in forestry and brush control applications.
Clopyralid
Clopyralid is a picolinic acid herbicide selective for broadleaf weeds in turf and cereals. Its pyridine carboxylic acid structure qualifies as aromatic heterocyclic under HTS 2934.99.1500. Known for excellent crop selectivity and residual soil activity.
Fluroxypyr
Fluroxypyr is a pyridyloxyacetic acid herbicide for broadleaf weed control in cereals. The aromatic pyridine structure with fluorine substitution qualifies under HTS 2934.99.1500. Rapidly translocated systemic action provides quick visual results.
Picloram
Picloram is a pyridine carboxylic acid herbicide for deep-rooted perennial weeds. Used in rangeland and non-crop areas, its heterocyclic structure qualifies under HTS 2934.99.1500. Long soil residual activity provides season-long control.
Aminopyralid
Aminopyralid is a highly active pyridine herbicide for broadleaf weeds in pastures. Extreme potency (active at grams per acre) with heterocyclic pyridine structure under HTS 2934.99.1500. Provides residual control up to 2 years.
