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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If racemic mecoprop without enantiomeric enrichment
While specific naming targets the compound regardless of chirality, unenriched forms sometimes declare under other aromatic acids.
If technical mixtures containing 80-95% mecoprop-P with isomers
Chemical mixtures not meeting 'separate chemically defined' criteria classify as preparations of Chapter 38.
If imported as sodium salt in aqueous solution for safety transport
Solutions of Chapter 29 compounds in water qualify only if normal for safety/transport per chapter note (e).

Import Tips & Compliance
• Include chirality specification and enantiomeric excess data in technical documentation
• 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
