3402.42.20/Coconut Diethanolamide Surfactant/Japan

Coconut Diethanolamide Surfactant from Japan

Coconut diethanolamide (CDEA) is a non-ionic surfactant derived from coconut fatty acids of vegetable origin, used primarily as a foam booster and thickener in shampoos and liquid soaps. It meets the Chapter 34 definition for organic surface-active agents by forming stable emulsions and reducing surface tension when mixed with water. Classified under HTS 3402.42.20 due to its fatty substance base from vegetable sources and non-ionic properties.

Import Tips

• Verify compliance with the 0.5% water mixture test for surface tension reduction to confirm non-ionic classification under heading 3402

• Provide certificates of analysis showing vegetable origin (e.g

• coconut fatty acids) to avoid reclassification to synthetic categories

• Label technical data sheets accurately to prevent customs disputes over 'fatty substance' status versus soap-like products
