Subheadings
Products classified under HTS 2918.99.20
2,4-Dichlorophenoxyacetic Acid (2,4-D)
2,4-D is an aromatic carboxylic acid with additional oxygen function used as a systemic herbicide for broadleaf weed control in agriculture. It falls under HTS 2918.99.20 as an aromatic pesticide, being a chlorinated phenoxyacetic acid derivative. This chemically defined organic compound matches the chapter's scope for carboxylic acids with oxygen functions.
4-(2,4-Dichlorophenoxy)butyric Acid (2,4-DB)
2,4-DB is a selective herbicide, an aromatic carboxylic acid with ether oxygen linkage, used on legumes and soybeans. It fits HTS 2918.99.20 as an 'other' pesticide, chemically defined per chapter (a). Metabolizes to 2,4-D in plants.
Dicamba (3,6-Dichloro-2-methoxybenzoic Acid)
Dicamba is a benzoic acid derivative with additional oxygen (methoxy) function, halogenated, used as a broad-spectrum herbicide. It qualifies for HTS 2918.99.20 as an aromatic pesticide, being chemically defined without exclusions. Primarily applied post-emergence in crops like soybeans.
Mecoprop (2-(2-Methyl-4-chlorophenoxy)propanoic Acid)
Mecoprop is an aromatic herbicide selective for broadleaf weeds, featuring a carboxylic acid with ether oxygen function and chlorination. Classified in HTS 2918.99.20 as an 'other' aromatic pesticide, it is a pure chemically defined compound per chapter notes. Used in turf and agricultural applications.
Clopyralid (3,6-Dichloro-2-pyridinecarboxylic Acid)
Clopyralid is a picolinic acid herbicide with pyridine ring, carboxylic acid, and additional oxygen potential via derivatives, but pure form fits. Under HTS 2918.99.20 as aromatic pesticide (pyridine considered aromatic). Controls thistles and composites.
Fluoroxypyr (4-Amino-3,6-dichloro-2-pyridinecarboxylic Acid)
Fluoroxypyr is a systemic auxin herbicide mimicking plant growth regulators, an aromatic pyridine carboxylic acid with amino substituent. HTS 2918.99.20 covers it as 'other' pesticide. Used for grassy weed control.
Picloram (4-Amino-3,5,6-trichloro-2-pyridinecarboxylic Acid)
Picloram is a persistent broadleaf herbicide, pyridine-based aromatic carboxylic acid with chlorine substitutions. Fits HTS 2918.99.20 as pesticide-technical grade. Controls woody plants and brush.
