Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as hydrochloride salt
Inorganic salts of organic compounds like p-aminobenzamide are classified with the parent compound per Chapter 29 note 3(C)(1), but if differing significantly, may shift to amine-function heading.
If for industrial dye production use
If put up specifically for dye synthesis and meeting azo dye diluent criteria per Chapter note (h), it dilutes to heading 2933; otherwise remains in 2924.
If dissolved in solvent for transport
Solutions in solvents for safety/transport per Chapter note (e) stay in Chapter 29, but if rendered suitable for specific use beyond general, may classify as chemical preparation in 3824.

Import Tips & Compliance
• Verify purity certificate (≥98%) and CAS number (2835-37-0) on commercial invoice to confirm classification; ensure SDS includes handling as irritant
• Avoid misdeclaration as dye intermediate (Chapter 32) which is excluded from Chapter 29

4-Aminobenzamide Powder
High-purity 4-aminobenzamide powder (synonym for p-aminobenzamide) is a white crystalline aromatic amide used primarily as a reagent in organic synthesis. Classified under HTS 2924.29.77.30 due to its specific chemical structure as a para-substituted benzamide, fitting 'other aromatic' cyclic amides. It complies with Chapter 29 scope for separate chemically defined compounds.
Para-Aminobenzamide Technical Grade
Technical grade para-aminobenzamide is an aromatic amide compound with 95-98% purity, used in agrochemical and polymer intermediate production. It matches HTS 2924.29.77.30 as 'other' aromatic cyclic amide, distinct from excluded coloring matters (Chapter 32). The compound's carboxyamide function on benzene ring dictates classification.
p-Aminobenzamide with Stabilizer
p-Aminobenzamide stabilized with anticaking agent for safe transport, maintaining its identity as a pure aromatic amide. Allowed under Chapter 29 note (f) for stabilizers necessary for preservation, thus remains in HTS 2924.29.77.30. Used in fine chemical manufacturing without rendering it for specific use.
Benzamide, 4-amino- USP Grade
USP-grade benzamide, 4-amino- (p-aminobenzamide) meets pharmaceutical standards for drug intermediate synthesis. Its classification in HTS 2924.29.77.30 stems from being a separate chemically defined aromatic cyclic amide, excluded from hormones (2937) or enzymes. Purity exceeds 99% for medicinal applications.
