Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is a derivative such as an ester or halide of isobutyric acid
Derivatives of saturated acyclic monocarboxylic acids are classified under the same heading, but specific derivatives may fall under residual subheadings.
If the product is actually butyric acid or its salts/esters
Butyric acid and its derivatives are specifically classified under subheading 2915.60.
