Linear Alkylbenzene Sulfonate (LAS) from Canada

LAS is a primary anionic synthetic surfactant used in laundry and dishwashing detergents for its excellent foaming and cleaning properties. It meets the Chapter 34 definition for organic surface-active agents by reducing surface tension in water solutions and forming stable emulsions. Classified under 3402.90.10 as a synthetic detergent, distinct from soap.

Import Tips

Verify surfactant concentration meets 0.5% water test for surface tension reduction per Chapter notes to avoid reclassification

Provide Safety Data Sheets (SDS) and purity certificates; common pitfall is mislabeling as soap leading to 3401 duties

Ensure CAS number documentation (e.g

27176-87-0) for customs verification of synthetic composition
