Heading 2935Sulphonamides

Chapter 29: Organic chemicals

Plain-language overview

Use HS-6 293590 when importing or exporting sulphonamides that are not specifically classified elsewhere in heading 2935. For example, a shipment of a sulphonamide compound used in pharmaceuticals would fall under this code.

This code is distinct from HS-6 293510, which covers specific sulphonamides like sulfanilamide. If your product is a more complex sulphonamide blend or a derivative not listed specifically, HS-6 293590 is the appropriate classification.

Sulphonamides are primarily used in medicinal applications, such as antibiotics or anti-inflammatory drugs. If you have a sulphonamide that doesn't fit the defined categories, this code provides a catch-all for those unique formulations.

When dealing with sulphonamides, ensure you check the chemical composition and intended use of your product. This will help determine if HS-6 293590 is the right choice or if you should look at other subheadings.
