Import Tips
• LABSA is often a mixture of homologues and isomers; Chapter 29 Note 1(b) covers mixtures of isomers of the same organic compound
• Ensure the product is not formulated with other ingredients for direct use as a detergent, which would change classification
• Keep the alkyl chain distribution analysis to support the chemical identity
