Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing a phenol function alongside the ketone
Phenol-function compounds take precedence and are classified later in numerical order per chapter note on oxygen functions.
If supplied as a cyclic polymer or contains ring heteroatoms from cyclization
Chapter note excludes certain cyclic structures from 2932-2934, pushing classification back to earlier ester headings.
If diluted with solvents for safety/transport beyond normal putting up
Solutions not solely for safety/transport fall outside chapter 29 per note (e), moving to mixtures of chapter 38.

Import Tips & Compliance
• Provide detailed chemical analysis (NMR, GC-MS) to confirm identity and purity as per chapter note (a) for separate chemically defined compounds
• Ensure SDS and handling instructions accompany shipments due to reactivity of keto-esters; verify no added solvents render it for specific use per note (e)
• Avoid misclassification as mixtures; single isomer purity must be documented to prevent reclassification under chapter 27 hydrocarbons
