Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing heterocyclic ring structure
Chapter 29 note excludes heterocyclic compounds from acyclic acid headings; classified by ring structure instead.
If for pesticide/herbicide end-use formulations
Pesticides containing these acids as active ingredients classified by end-use in Chapter 38.
If specifically enumerated in statistical breakout
More specific 10-digit statistical suffixes exist for certain isomers within the 2915.90 heading.

Import Tips & Compliance
• Include GC-MS analysis confirming >98% purity to avoid mixture classification in Chapter 38
• Declare correct UN 3265 (corrosive liquid, acidic) for DOT/IMDG shipping compliance
• Verify not classifiable as formic/acetic (2915.11-13) by molecular structure documentation
