Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other aromatic amino acid esters not specifically named
Moves to residual 'other' subheading within same aromatic category
If the amino group is absent or considered secondary
Pure carboxylic acid esters without prominent amino function classify under 2918
If when imported as part of azo dye coupler mixture
Mixtures for dye production may shift to heterocyclic provisions

Import Tips & Compliance
• Submit GC-MS purity certificate (>97%) and confirm methyl ester via saponification value
• Declare chlorine position (3-position) via NMR to distinguish from other isomers
• Package under nitrogen with BHT stabilizer if required for transport stability
