HS-4 · Heading
2901 — Acyclic hydrocarbons
Chapter 29: Organic chemicals
Plain-language overview
Use HS-4 2901 when importing or exporting acyclic hydrocarbons, such as a shipment of propylene gas used in the production of plastics. This heading includes both saturated and unsaturated hydrocarbons, which are key raw materials in various chemical processes.
When deciding between the subheadings, consider the saturation level and specific type of hydrocarbon. For example, HS-6 290110 covers saturated hydrocarbons, while HS-6 290121 is for unsaturated ethylene. If you’re dealing with butylene, you would look at HS-6 290123.
The distinction between unsaturated hydrocarbons is crucial. If your product is buta-1,3-diene or isoprene, you’ll use HS-6 290124. For other unsaturated hydrocarbons not specifically listed, refer to HS-6 290129.

- What are acyclic hydrocarbons?
- Acyclic hydrocarbons are organic compounds made up of hydrogen and carbon atoms that do not form a ring structure. They can be saturated or unsaturated.
- How do I determine the correct HS-6 code for my shipment?
- Identify the saturation level and specific type of hydrocarbon in your shipment to select the appropriate HS-6 code from the subheadings under HS-4 2901.
- What is the difference between saturated and unsaturated hydrocarbons?
- Saturated hydrocarbons contain only single bonds between carbon atoms, while unsaturated hydrocarbons have at least one double or triple bond.
- Can I use a single HS code for different types of hydrocarbons?
- No, each type of hydrocarbon has a specific HS-6 code based on its structure and saturation level. Choose the code that precisely matches your product.
- Are there any restrictions on importing acyclic hydrocarbons?
- Yes, specific regulations may apply depending on the type of hydrocarbon and the country of import. Always check local customs regulations.
