HS-6 · Subheading
290436
Derivatives of hydrocarbons; perfluorooctane sulphonyl fluoride, whether or not halogenated
Heading 2904 — Sulphonated, nitrated or nitrosated derivatives of hydrocarbons; whether or not halogenated
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 290436 when importing or exporting perfluorooctane sulphonyl fluoride, a chemical often used in industrial applications such as surfactants or coatings. For instance, if you're shipping a batch of this chemical in 50 kg drums, this code applies.
This code specifically covers derivatives of hydrocarbons that are sulphonated, nitrated, or nitrosated, with a focus on perfluorinated compounds. It's essential to distinguish it from HS-6 290437, which pertains to other sulphonated derivatives that may not include the perfluorinated aspect.
When classifying your product, ensure it matches the criteria of being a derivative of hydrocarbons, particularly if it involves perfluorooctane sulphonyl fluoride. This is crucial for compliance with customs regulations.
If your product is a similar sulphonated hydrocarbon but does not contain the perfluorinated element, you may need to look at different HS codes under the same heading.
