High-Purity Phenylacetic Acid for Fragrance Synthesis
Ultra-high purity phenylacetic acid specifically for synthesizing benzyl acetate and other fragrance compounds in perfumery. Covered by HTS 2916.34.25.00 under additional U.S. note 3 to section VI due to regulatory controls on precursor chemicals. As a chemically defined aromatic monocarboxylic acid, it precisely matches the heading despite end-use in non-pharma applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-regulated purity grades
Lower purity or non-note 3 products use standard subheading.
If further processed into coumarin derivatives
Mixtures of odoriferous substances from phenylacetic acid shift to chapter 33.
If converted to heterocyclic derivatives
Chapter notes exclude certain cyclic derivatives from 2932, but processing changes classification.

Phenylacetic Acid USP Grade
High-purity phenylacetic acid meeting United States Pharmacopeia (USP) standards, used primarily as an intermediate in pharmaceutical synthesis for antibiotics like penicillin derivatives. Classified under HTS 2916.34.25.00 as a product described in additional U.S. note 3 to section VI, which covers specific chemical substances subject to quota restrictions. Its aromatic monocarboxylic acid structure with the formula C6H5CH2COOH fits the heading for phenylacetic acid and its salts.
Phenylacetic Acid 99% Technical Grade
Technical grade phenylacetic acid with 99% purity, utilized in chemical manufacturing for pesticides, fragrances, and as a precursor in organic synthesis. Falls under HTS 2916.34.25.00 due to its status in additional U.S. note 3 to section VI, imposing import quotas on regulated phenylacetic acid products. As an aromatic monocarboxylic acid derivative, it matches the precise chemical definition of the heading.
Sodium Phenylacetate Pharmaceutical Grade
Pharmaceutical-grade sodium phenylacetate, the sodium salt of phenylacetic acid, used in treatments for urea cycle disorders and as an ammonia scavenger. Classified in HTS 2916.34.25.00 as a derivative covered by additional U.S. note 3 to section VI, despite being a salt, due to specific U.S. provisions for regulated precursors. Its structure retains the core phenylacetic acid moiety qualifying under the heading.
Phenylacetic Acid Flakes Stabilized
Stabilized phenylacetic acid in flake form with added anticaking agent for safe transport and storage, used in industrial synthesis of cephalosporin antibiotics. HTS 2916.34.25.00 applies per additional U.S. note 3 to section VI for quota-controlled products; chapter note (f) keeps it in chapter 29 as the stabilizer is necessary for preservation. Retains classification as aromatic monocarboxylic acid derivative.
Phenylacetic Acid Anhydride
Phenylacetic anhydride, the cyclic or linear anhydride form of phenylacetic acid, used as an acetylating agent in pharmaceutical and fine chemical production. HTS 2916.34.25.00 includes such derivatives described in additional U.S. note 3 to section VI for quota purposes. Heading covers anhydrides of aromatic monocarboxylic acids like phenylacetic acid.
