Products classified under HTS 2915.90.18.90
Isobutyric Acid
Isobutyric acid (2-methylpropanoic acid) is a saturated acyclic monocarboxylic acid used in organic synthesis, flavorings, and as an intermediate for pharmaceuticals. It falls under HTS 2915.90.18.90 as a saturated acyclic monocarboxylic acid not elsewhere specified in heading 2915. This classification follows Chapter 29 notes for separate chemically defined organic compounds.
Pivalic Acid
Pivalic acid (trimethylacetic acid, 2,2-dimethylpropanoic acid) is a branched saturated acyclic monocarboxylic acid used in pharmaceuticals, pesticides, and polymer synthesis. Classified under HTS 2915.90.18.90 as 'other' saturated acyclic monocarboxylic acids per Chapter 29 structure-based classification.
2-Ethylhexanoic Acid
2-Ethylhexanoic acid is a saturated acyclic branched-chain monocarboxylic acid used in paint driers, PVC stabilizers, and metal soaps. It qualifies for HTS 2915.90.18.90 as a non-enumerated saturated acyclic monocarboxylic acid under Chapter 29 heading 2915 structure rules.
Neodecanoic Acid
Neodecanoic acid (versatic acid) is a highly branched saturated acyclic C10 monocarboxylic acid used in synthetic lubricants, paint coalescents, and metalworking fluids. Falls under HTS 2915.90.18.90 per Chapter 29 for other saturated acyclic monocarboxylic acids.
2-Methylbutyric Acid
2-Methylbutyric acid is a C5 branched saturated acyclic monocarboxylic acid with natural apple-like odor, used in flavors, fragrances, and pharmaceuticals. Classified in HTS 2915.90.18.90 as other saturated acyclic monocarboxylic acids not specifically named in prior subheadings.
Valproic Acid
Valproic acid (2-propylpentanoic acid) is a branched-chain saturated acyclic monocarboxylic acid used as an antiepileptic drug and mood stabilizer. It falls under HTS 2915.90.18.90 as a saturated acyclic monocarboxylic acid prior to pharmaceutical formulation per Chapter 29 classification rules.
Cyclohexanecarboxylic Acid
Cyclohexanecarboxylic acid contains a saturated cyclohexane ring making it cycloaliphatic rather than acyclic, but sometimes misclassified. Actually belongs in 2916.20, shown here to illustrate common error vs true 2915.90.18.90 acyclic products.
3-Methylbutyric Acid (Isovaleric Acid)
Isovaleric acid (3-methylbutanoic acid) is a saturated acyclic branched C5 monocarboxylic acid with strong cheesy odor, used in flavors and biochemical research. Classified HTS 2915.90.18.90 as other saturated acyclic monocarboxylic acids.
2-Propylpentanoic Acid
2-Propylpentanoic acid, a C8 branched saturated acyclic monocarboxylic acid, serves as intermediate for pharmaceuticals and lubricants. HTS 2915.90.18.90 classification for non-specific saturated acyclic monocarboxylic acids.
Neoheptanoic Acid
Neoheptanoic acid is a highly branched saturated acyclic C7 monocarboxylic acid used in specialty esters and synthetic lubricants. Falls under HTS 2915.90.18.90 as other saturated acyclic monocarboxylic acids per Chapter 29.
