Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If statistical breakout for specific ethyl esters if separately tracked
Heading provides for separate reporting of certain ethyl ester variants.
If classified by ester oxygen function rather than sulfo parent
Oxygen-function classification could apply if sulfo group not principal characteristic.

Import Tips & Compliance
• Confirm esterification with ethanol per chapter note 3(B); other alcohol esters may classify differently
• Provide refractive index and boiling point data matching published specifications
• Store/transport away from water to prevent hydrolysis back to sulfonic acid
