Isobutyric Acid
Isobutyric acid (2-methylpropanoic acid) is a saturated acyclic monocarboxylic acid used in organic synthesis, flavor production, and as an intermediate for pharmaceuticals. It falls under HTS 2915.90.50.50 as 'other' saturated acyclic monocarboxylic acids that are not specifically named elsewhere in heading 2915. This classification applies to its chemical structure as a branched chain C4 acid.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If straight-chain C5 acid like valeric acid
Straight-chain pentanoic acid derivatives classified specifically under 2915.70, while branched isomers fall to 'other'.
If imported as mixture with solvents exceeding safety/transport limits
Solutions where solvent renders product suitable for specific use move to Chapter 38 mixtures.
If esterified with ethyl alcohol
Ethyl esters of saturated acyclic monocarboxylic acids classified with parent acid per Chapter 29 note 3(A)(B).

Import Tips & Compliance
• Provide detailed chemical analysis (GC-MS, NMR) confirming purity and structure to verify classification under 2915
• Include Safety Data Sheets (SDS) and ensure proper UN packaging for corrosive acids during transport
• Avoid misclassification as aromatic acids (2904) by documenting saturated aliphatic nature
