Products classified under HTS 2918.99.14.00
Mecoprop (MCPP) Technical Grade
Mecoprop, chemically 2-(4-chloro-2-methylphenoxy)propionic acid, is a synthetic auxin herbicide used for selective broadleaf weed control in turf and lawns. It falls under HTS 2918.99.1400 as a chemically defined aromatic carboxylic acid with additional oxygen function in the phenoxy group. This technical grade is the pure active ingredient before formulation.
Mecoprop Sodium Salt
The sodium salt of 2-(4-chloro-2-methylphenoxy)propionic acid (mecoprop sodium) is a water-soluble herbicide active ingredient used in lawn care products. HTS 2918.99.1400 specifically covers this compound and its salts as aromatic carboxylic acids with oxygen function. The salt form improves solubility for formulation into sprays.
MCPP-P (Mecoprop-P) Acid
Mecoprop-P is the enriched (R)-enantiomer of 2-(4-chloro-2-methylphenoxy)propionic acid, offering higher herbicidal potency with reduced dosage. It qualifies under HTS 2918.99.1400 as the specific chemically defined aromatic compound and its salts. This chiral form provides better environmental profile than racemic mixture.
Mecoprop Ammonium Salt
Ammonium mecoprop [ammonium 2-(4-chloro-2-methylphenoxy)propionate] provides volatility control in herbicide formulations for turf applications. Classified under HTS 2918.99.1400 per Chapter 29 note on organic salts of acid-function compounds. The ammonium counterion maintains classification with the parent carboxylic acid.
Mecoprop Free Acid 98% Technical
High-purity 98% mecoprop free acid serves as the reference standard for analytical chemistry and formulation quality control. HTS 2918.99.1400 covers this specific aromatic phenoxypropionic acid as a separate chemically defined organic compound. Minor impurities do not affect classification per chapter notes.
Mecoprop-P Potassium Salt
Potassium salt of (R)-mecoprop provides excellent cold-water solubility for ready-to-use herbicide concentrates. Falls under HTS 2918.99.1400 as salt of the specified carboxylic acid with additional oxygen function. Preferred for organic turf management programs.
