Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If considered primarily as p-aminobenzoic acid salts without ester
Base carboxylic acid salts without ester oxygen function shift to earlier 2924 headings per numerical order rule.
If bulk drug mixed with excipients for bulk medicinal use
Admixtures exceeding simple solutions fall under Chapter 30 medicaments when not purely chemically defined.

Import Tips & Compliance
• Label as USP-grade with CAS number (51-05-8); include pharmacopeia certificates to confirm drug status
• Document ester-salt structure to prevent reclassification; common issue is declaring as base form only
• For frozen shipments, note stabilizer additions per Chapter 29(g) to avoid duty disputes
