Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a formulated herbicide product with adjuvants
Pesticide formulations or preparations put up for retail sale fall under Chapter 38, not pure active ingredients.
If non-aromatic (aliphatic) structure
Aliphatic carboxylic acids with additional oxygen function are classified under the non-aromatic subheading.
If imported as its sodium salt
Inorganic salts of organic acids are classified with the organic acid, but specific pesticide salts may shift to nucleoside analogs or other heterocyclic provisions.

Import Tips & Compliance
• Obtain EPA registration number and ensure product labeling complies with FIFRA for pesticide imports
• Provide Certificate of Analysis confirming purity as a chemically defined aromatic carboxylic acid derivative
• Verify not excluded under chapter notes (e.g
• not a salt or ester classified elsewhere); common pitfall is confusing with formulations
