Isovaleric Acid
Isovaleric acid (3-methylbutanoic acid) is a branched saturated acyclic monocarboxylic acid with a pungent odor, used in food flavoring, perfumes, and pharmaceuticals. It qualifies for HTS 2915.90.18 as an 'other' acid in this saturated acyclic category, distinct from straight-chain C1-C8 acids listed separately.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains unsaturation or is an unsaturated analog
Saturated acids stay in 2915; any double bonds would move it to heading 2916 for unsaturated acyclic monocarboxylic acids.
If when highly diluted in retail fragrance preparations
If put up for retail sale as a consumer product rather than bulk chemical, it falls under Chapter 33 for mixtures of odoriferous substances.

Import Tips & Compliance
• For food-grade imports, provide FDA prior notice and GRAS affirmation letters; use UN 1760 packaging for corrosive liquids; test for chiral purity if specified for pharma intermediates

Valproic Acid
Valproic acid is a saturated acyclic monocarboxylic acid with an eight-carbon chain and a branched structure, used primarily as an anticonvulsant medication for epilepsy and bipolar disorder. It falls under HTS 2915.90.18 as an 'other' saturated acyclic monocarboxylic acid that is not formic, acetic, propionic, butyric, valeric, caproic, or caprylic acid. This classification aligns with Chapter 29 notes for separate chemically defined organic compounds.
Isobutyric Acid
Isobutyric acid (2-methylpropanoic acid) is a branched-chain saturated acyclic monocarboxylic acid used in organic synthesis, flavor production, and as an intermediate for resins. Classified under HTS 2915.90.18 as it doesn't match the named straight-chain acids in the heading. Meets Chapter 29 requirements for chemically defined organic compounds with carboxylic acid function.
2-Ethylhexanoic Acid
2-Ethylhexanoic acid is a synthetic branched-chain saturated acyclic monocarboxylic acid used in metal soap production, PVC stabilizers, and lubricants. HTS 2915.90.18 covers this as an 'other' acid beyond the principal straight-chain examples, per Chapter 29's scope for chemically defined compounds.
Neodecanoic Acid
Neodecanoic acid is a highly branched saturated acyclic monocarboxylic acid (versatic acid) used in paint driers, polymer synthesis, and corrosion inhibitors. It fits HTS 2915.90.18 as an 'other' saturated acyclic monocarboxylic acid not specifically named in prior subheadings.
Pivalic Acid
Pivalic acid (trimethylacetic acid) is a sterically hindered saturated acyclic monocarboxylic acid used in pharmaceuticals, pesticides, and polymer synthesis. Classified in HTS 2915.90.18 as it represents 'other' saturated acyclic monocarboxylic acids outside the straight-chain C1-C8 series.
2-Methylbutyric Acid
2-Methylbutyric acid is a chiral branched saturated acyclic monocarboxylic acid used in flavorings and as a chemical intermediate. It falls under HTS 2915.90.18 as an 'other' acid, meeting Chapter 29 criteria for pure organic compounds with single carboxylic function.
