HS-6 · Subheading
290435
Derivatives of hydrocarbons; salts of perfluorooctane sulphonic acid n.e.c in heading no. 2904, 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 290435 when importing or exporting specific derivatives of hydrocarbons, particularly those that are sulphonated, nitrated, or nitrosated. For example, if you're shipping a chemical compound like a sulphonated hydrocarbon used in industrial applications, this code applies.
This code narrows down the broader category of organic chemicals under chapter 29 to focus on specific derivatives of hydrocarbons. Unlike HS-6 290431, which covers different salts, HS-6 290435 is specifically for those not classified elsewhere in heading 2904.
When considering HS-6 290435, think about products such as perfluorooctane sulfonic acid derivatives. These compounds are often used in applications like surfactants, lubricants, or as processing aids in various industrial sectors.
If you're unsure whether your product fits here, consider the characteristics of your chemical. For instance, if it’s a sulphonated derivative that does not fall under other specific categories, this code is likely appropriate.
