3402.41.90.00 - Other 🖩

This category, HTS 3402.41.90.00, encompasses "Other" cationic organic surface-active agents, excluding those of a specifically aromatic or modified aromatic nature. These agents are characterized by having a positively charged hydrophilic group. This broad classification covers a wide array of cationic surfactants that do not fit into the more specific "Aromatic or modified aromatic" sibling category (3402.41.10.00). The distinction lies in the chemical structure of the aromatic or modified aromatic component.

The products classified here are primarily utilized for their surface-active properties, including emulsifying, wetting, foaming, or dispersing capabilities. Examples may include certain quaternary ammonium compounds or other cationic molecules that serve as ingredients in industrial cleaning agents, fabric softeners, corrosion inhibitors, asphalt emulsifiers, or as intermediates in further chemical synthesis. Classification hinges on the absence of a prominent aromatic core structure as defined in the sibling category, and the presence of a cationic charge in the molecule.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the practical application of this classification relies on a thorough understanding of the parent heading's scope for organic surface-active agents and the specific definition of "cationic" in chemical terms, differentiating it from the more narrowly defined aromatic cationic surfactants.
