Import Tips
• Note that commercial dodecylbenzene sulfonic acid may be a mixture of isomers; Chapter 29 Note 1(b) allows mixtures of isomers of the same organic compound
• Verify the product is not put up for retail sale as a cleaning preparation, which could shift classification to Chapter 34
• Provide the acid value and molecular weight data to support the declaration
