How do I determine if my product is halogenated?

Check the chemical structure of your product. If it contains halogen atoms (like chlorine or bromine), it is considered halogenated.

What is the difference between HS-6 290410 and 290420?

HS-6 290410 is for derivatives with only sulpho groups, while HS-6 290420 is for those containing only nitro or nitroso groups.

Can I use HS-4 2904 for all derivatives of hydrocarbons?

No, HS-4 2904 specifically covers sulphonated, nitrated, or nitrosated derivatives. Other types may fall under different headings.

What should I do if my product doesn't fit neatly into the HS-6 subheadings?

If your product is not specifically listed, you may need to use HS-6 290499, which covers derivatives n.e.c. (not elsewhere classified) in heading 2904.

Are there any special regulations for importing perfluorooctane sulphonates?

Yes, perfluorooctane sulphonates may be subject to specific environmental regulations due to their chemical properties. Always check local regulations.

HS-4 · Heading

2904 — Sulphonated, nitrated or nitrosated derivatives of hydrocarbons; whether or not halogenated

Chapter 29: Organic chemicals

Plain-language overview

Use HS-4 2904 when importing or exporting sulphonated, nitrated, or nitrosated derivatives of hydrocarbons, such as trichloronitromethane (chloropicrin). This code applies to various derivatives, including those that may be halogenated.

To choose the correct HS-6 line, consider the specific functional groups present in your product. For example, HS-6 290410 is for derivatives containing only sulpho groups, while HS-6 290420 covers those with only nitro or nitroso groups. Understanding these distinctions is crucial for proper classification.

If your product includes perfluorooctane sulphonate derivatives, you will need to differentiate among several HS-6 codes like 290431 for perfluorooctane sulphonic acid or 290432 for ammonium perfluorooctane sulphonate. Each has specific applications and regulatory requirements.
