Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a simple ketone without emphasized carboxylic/phenol function
Pure aromatic ketones without additional oxygen functions like hydroxy are classified under phenol-ketone derivatives in 2914.
If for industrial use as phenolic intermediate rather than finished stabilizer
Simple phenolic compounds (hydroxybenzene derivatives) fall under Chapter 29 phenols if not presented with ketone function prominently.
If imported as mixture or preparation with solvents exceeding chapter note limits
Chemical preparations not chemically defined as single compounds are classified in heading 3824.

Import Tips & Compliance
• Verify the product matches the exact chemical description in additional U.S. note 3 to section VI to avoid reclassification
• Provide Certificate of Analysis (COA) and SDS confirming purity and aromatic structure during customs entry
• Ensure proper HAZMAT labeling as it may be irritant; common pitfall is incorrect storage class declaration
