HS-6 · Subheading
291830
Acids; carboxylic acids, (with aldehyde or ketone function but without other oxygen function), their anhydrides, halides, peroxides, peroxyacids and their derivatives
Heading 2918 — Acids; carboxylic acid with additional oxygen function and their anhydrides, halides, peroxides, peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 291830 when importing or exporting carboxylic acids that contain aldehyde or ketone functions but lack other oxygen functions. A common example is 2-butanedioic acid, which may be shipped in bulk containers for use in food additives or chemical manufacturing.
This HS-6 code specifically covers acids like 2-butanedioic acid, distinguishing them from HS-6 291831, which includes similar acids with additional oxygen functionalities. This distinction is crucial for correct classification and compliance with customs regulations.
When dealing with HS-6 291830, ensure that your products do not contain other oxygen functions, as this could lead to misclassification. For instance, if your shipment includes 3-hydroxybutanoic acid, it would not fall under this code due to the presence of an additional hydroxyl group.
Understanding the nuances of this HS-6 line helps prevent delays at customs. Always verify the chemical structure of your products against this classification to avoid potential issues during import or export.

Questions & answers
For orientation only—the binding text is your national tariff and the WCO nomenclature your country uses.
- What types of products are classified under HS-6 291830?
- HS-6 291830 covers carboxylic acids that contain aldehyde or ketone functions without additional oxygen functions, such as 2-butanedioic acid.
- How can I ensure my product is correctly classified?
- Verify the chemical structure of your product against the definitions in the HS code. If it contains only aldehyde or ketone functions, it likely falls under HS-6 291830.
- Are there specific packaging requirements for shipping these acids?
- Yes, ensure that your acids are packaged in compliant containers, such as bulk drums or ISO tanks, and labeled correctly according to safety regulations.
- What should I do if my product has additional oxygen functions?
- If your product has additional oxygen functions, it may fall under a different HS code, such as **HS-6 291831**. Consult with a customs broker for accurate classification.
- Can I import 2-butanedioic acid for food use?
- Yes, but ensure it meets food safety regulations and is properly classified under HS-6 291830 for customs clearance.
- What documentation do I need for importing carboxylic acids?
- You will need a commercial invoice, packing list, and possibly a safety data sheet (SDS) to comply with customs requirements.
- Is there a risk of delays at customs for these products?
- Yes, misclassification or incomplete documentation can lead to delays. Ensure all information is accurate and complete.
- What are the potential uses for carboxylic acids classified under HS-6 291830?
- These acids are often used in food additives, pharmaceuticals, and chemical manufacturing processes.
