Mecoprop-p (2-(4-chloro-2-methylphenoxy)propanoic acid)
Mecoprop-p is a chiral aromatic herbicide, a phenoxypropionic acid derivative used for selective control of broadleaf weeds in turf and cereals. Classified under HTS 2918.99.2050 due to its aromatic structure, carboxylic acid with phenoxy oxygen function, and primary pesticide application. It meets Chapter 29 criteria as a separate chemically defined organic compound.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when sold as emulsifiable concentrate or with surfactants
Any formulation beyond pure technical material moves to Chapter 38 pesticide headings.
If not explicitly used as a pesticide
Lacks specific pesticide designation; defaults to general aromatic carboxylic acids.
If regarded primarily as a saturated acyclic acid derivative
Propanoic acid structure could lead to classification under earlier oxygen-function headings if aromaticity is downplayed.

Import Tips & Compliance
• Submit EPA Import Alert documentation and confirm enantiomeric purity if specified for the p-isomer
• Label shipments with UN number (2765 for phenoxy herbicides) and proper hazard class for DOT compliance
• Prevent reclassification pitfalls by including end-use statement affirming pesticide application

2,4-Dichlorophenoxyacetic acid (2,4-D)
2,4-D is an aromatic carboxylic acid with additional oxygen function, specifically a phenoxyacetic acid derivative used as a systemic herbicide for broadleaf weed control in agriculture. It falls under HTS 2918.99.2050 as an aromatic pesticide, being a chemically defined organic compound with the required functional groups. This classification reflects its primary use in crop protection rather than other chemical applications.
Dicamba (3,6-dichloro-2-methoxybenzoic acid)
Dicamba is an aromatic benzoic acid herbicide with a methoxy oxygen function, effective against broadleaf weeds in soybeans and cotton. It qualifies for HTS 2918.99.2050 as an 'other' aromatic pesticide carboxylic acid per Chapter 29 notes on oxygen functions. The pure technical grade is imported as a separate chemically defined compound.
4-CPA (4-chlorophenoxyacetic acid)
4-CPA is a plant growth regulator and herbicide, an aromatic phenoxyacetic acid with chlorine substitution, used for celery and tobacco defoliation. Under HTS 2918.99.2050 as an aromatic pesticide with carboxylic acid and ether oxygen functions. Complies with Chapter 29 scope for chemically defined pesticide compounds.
Fluoroxypyr-meptyl ester
Fluoroxypyr-meptyl is the methylheptyl ester of fluoroxypyr, an aromatic pyridine carboxylic acid herbicide for grassy and broadleaf weeds. Though an ester, Chapter Note 5(A) classifies it with the later-heading acid (2918) as a pesticide. HTS 2918.99.2050 covers this 'other' aromatic pesticide form.
Clopyralid (3,6-dichloro-2-pyridinecarboxylic acid)
Clopyralid is a picolinic acid herbicide, aromatic pyridinecarboxylic with chlorine, for perennial weed control in turf. Fits HTS 2918.99.2050 as other aromatic pesticide carboxylic acid with oxygen function. Chapter notes place esters/salts with the acid.
Picloram (4-amino-3,5,6-trichloro-2-pyridinecarboxylic acid)
Picloram, a pyridinecarboxylic acid herbicide for woody plants and brush, features amino and chloro groups on aromatic ring. HTS 2918.99.2050 for its pesticide use and carboxylic/oxygen functions. Excludes mixtures per chapter notes.
