Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 292330 when importing or exporting quaternary ammonium salts and hydroxides, such as tetraethylammonium perfluorooctane sulphonate. These compounds are often used in various applications, including surfactants and disinfectants.
This code specifically targets quaternary ammonium salts and hydroxides that may not be chemically defined. If you're dealing with similar products like amines or different types of surfactants, you might need to consider other HS codes, such as HS-6 292320 for amines.
When classifying under this HS-6, remember that the distinction lies in whether the compound is chemically defined or not. For example, tetraethylammonium perfluorooctane sulphonate is a specific compound that falls under this category, while more generic ammonium salts may not.
If you're unsure about the exact classification, consulting with a customs broker can clarify whether your product fits under HS-6 292330 or another related line.
