Dodecylbenzene Sulfonic Acid (DDBSA) from Japan

Dodecylbenzene Sulfonic Acid (DDBSA) is a modified aromatic sulfonic acid surfactant used in household and industrial cleaners. It qualifies as an organic surface-active agent under tariff item 3402.49.00 because it reduces surface tension and is not a separate chemically defined compound in its commercial form. DDBSA is typically supplied as a mixture with water or other solvents, making it classifiable under this item.

Import Tips

• Ensure the DDBSA is not a pure separate chemically defined compound; commercial grades with impurities or water are classifiable here

• Provide a certificate of analysis showing surface-active properties

• Check if the product is put up for retail sale, which may affect classification
