Last updated: July 2026 dataIbuprofen — classified at 2916391500 — is the most commercially prominent named compound in this residual aromatic monocarboxylic acid heading, and its import as a pharmaceutical active ingredient triggers FDA drug establishment registration and cGMP compliance requirements. China is the leading supplier across this heading, followed by Italy and India; Section 301 tariffs apply to Chinese-origin goods, a material cost factor for pharmaceutical and specialty chemical buyers. The heading also captures cinnamic acid (2916390600), used in fragrance and UV-filter applications, and several reactive intermediates including benzoic anhydride and tert-butyl peroxybenzoate (2916390300), which serve as acylating agents and polymerization initiators respectively.

Ibuprofen imported as a drug active pharmaceutical ingredient (API) is subject to FDA's drug cGMP regulations. The foreign manufacturing site must be registered with FDA, listed in the Drug Establishment Registration database, and subject to FDA inspection. The importer of record should also hold a valid drug establishment registration if it performs any manufacturing steps. Classification and admissibility are complex; consult a licensed customs broker or FDA's Office of Pharmaceutical Quality before importing.
The NESOI (not elsewhere specified or included) designation means this heading applies only after ruling out all more specific Chapter 29 provisions. Importers should work through the relevant chapter notes and, for compounds with pharmaceutical or agrochemical end uses, consider whether a more specific heading (e.g., for heterocyclic compounds or hormones) might apply. A CBP binding ruling is advisable for novel intermediates where classification is genuinely ambiguous.
