MCPP-P (Mecoprop-P) Acid from China
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.

• Register with EPA as new chemical if purity/enantiomer differs from existing tolerances
• Use refrigerated transport if stability data requires temperature control below 25°C
