Sodium Lauryl Sulfate Powder
Sodium Lauryl Sulfate (SLS) is an anionic surfactant commonly used in shampoos, toothpastes, and foaming cleansers. It meets the Chapter 34 definition for organic surface-active agents by reducing surface tension in water solutions to below 45 dyne/cm. Classified under 3402.39.90 as a non-soap anionic agent not put up for retail sale.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-ionic active agent
Non-ionic surfactants like alcohol ethoxylates fall under 3402.90, based on chemical structure and surface activity test.
If water-soluble soap base
Products meeting soap definition (water-soluble salts of fatty acids) shift to heading 3401.
If chemically defined compound
Chapter exclusion applies to separate chemically defined compounds, moving to Chapter 38.

Import Tips & Compliance
• Verify purity and active ingredient concentration via lab analysis to confirm anionic classification
• Include Safety Data Sheets (SDS) showing surface tension reduction test results per Chapter notes
• Avoid retail packaging; bulk shipments classified differently than consumer-ready products
