Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If incorrectly identified as ortho isomer
Salicylic acid (2-hydroxybenzoic acid) has a different specific subheading; isomers are distinguished by position.
If supplied as mixture with additives exceeding Chapter 29 tolerances
Mixtures not qualifying as chemically defined compounds fall into Chapter 38 as chemical preparations.
If in salt form like sodium m-hydroxybenzoate
Organic salts of these acids are classified under heading 2940 per Chapter 29 classification notes.

Import Tips & Compliance
• Provide Certificate of Analysis (CoA) confirming chemical purity and structure to verify classification under Chapter 29 note (a)
• Ensure proper Hazard Communication labeling (UN 2811) and SDS documentation for DOT/IATA transport compliance
• Avoid misclassification as salicylic acid (ortho isomer, 2918.21); specify meta position in documentation
