Sodium Lauryl Sulfate Powder
Sodium Lauryl Sulfate (SLS) is an anionic surfactant commonly used in shampoos, body washes, and toothpastes for its foaming and cleansing properties. 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 3402.39.90.50 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 surfactant like alcohol ethoxylates
Non-anionic surfactants fall under 3402.90, changing classification based on chemical ionic nature.
If product qualifies as water-soluble soap
Soap per Chapter Note 1 (water-soluble) moves to 3401 regardless of anionic properties.
If chemically defined as a single compound
Chapter exclusion for separate chemically defined compounds shifts to Chapter 38 preparations.

Import Tips & Compliance
• Verify surfactant type via lab analysis to confirm anionic classification under 3402; misclassification as soap leads to 3401
• Provide technical data sheets showing surface tension reduction <45 dyne/cm per Chapter Note 2 to avoid scrutiny
• Ensure bulk packaging documentation; retail-ready packs may shift to consumer product headings like 3402.50
