Use this as a comparison hint, then confirm the final decision with legal notes and country-specific rules.
HS-6 · Subheading
290420
Derivatives of hydrocarbons; containing only nitro or only nitroso groups, 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 290420 when importing or exporting nitro or nitroso derivatives of hydrocarbons, such as nitrobenzene or nitrosodimethylamine. These compounds are often used in the production of dyes, pharmaceuticals, and agrochemicals.
This code specifically covers derivatives that contain only nitro or nitroso groups, distinguishing them from other related compounds that may include additional functional groups. For example, HS-6 290421 includes derivatives with sulphonated groups, which are classified differently.
When considering HS-6 290420, be aware that it applies to products that may be halogenated or non-halogenated. If your product has multiple functional groups, you may need to look at other classifications under the same heading.
If you are unsure whether your product fits this classification, check the chemical structure and ensure it contains only nitro or nitroso groups. This specificity can help avoid misclassification and potential customs issues.

- What types of products are classified under HS 290420?
- HS 290420 covers nitro or nitroso derivatives of hydrocarbons, such as nitrobenzene, nitrosodimethylamine, and other similar compounds.
- How can I determine if my product is halogenated?
- Check the chemical structure of your product. If it contains halogen atoms (like chlorine or bromine) attached to the hydrocarbon, it is considered halogenated.
- Can I classify a product with both nitro and other groups under HS 290420?
- No, HS 290420 is specific to products containing only nitro or nitroso groups. If your product has additional functional groups, it may fall under a different classification.
- What should I do if I'm unsure about the classification?
- Consult with a customs broker or refer to the official customs tariff guide for clarification on the specific chemical structure and classification.
- Are there any restrictions on importing nitro compounds?
- Certain nitro compounds may be subject to regulations or restrictions due to their potential use in explosives or hazardous materials. Always check local regulations.
- What is the difference between HS 290420 and HS 290421?
- HS 290420 covers derivatives with only nitro or nitroso groups, while HS 290421 includes derivatives that also contain sulphonated groups.
- How do I find the correct HS code for my chemical product?
- Identify the chemical structure and functional groups of your product, then consult the customs tariff or a customs broker for the appropriate classification.
- What are common uses for nitro derivatives?
- Nitro derivatives are commonly used in the production of dyes, pharmaceuticals, agrochemicals, and as solvents in chemical reactions.
