Use this as a comparison hint, then confirm the final decision with legal notes and country-specific rules.
HS-6 · Subheading
290373
Halogenated derivatives of acyclic hydrocarbons containing two or more different halogens; dichlorofluoroethanes (HCFC-141, 141b)
Heading 2903 — Halogenated derivatives of hydrocarbons
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 290373 when importing or exporting halogenated derivatives of acyclic hydrocarbons, specifically those containing two or more different halogens, like dichlorofluoroethanes. For example, if you’re shipping HCFC-141b for use in refrigeration, this is the correct code.
This HS-6 code is distinct from HS-6 290371, which covers similar compounds but is limited to those with only one type of halogen. If your product has multiple halogens, such as a mixture of chlorine and fluorine, you'll need to use 290373.
The classification under this code includes products like dichlorofluoroethane (HCFC-141) and its variants, which are often used as solvents or refrigerants. Ensure your product specifications match this description to avoid misclassification.
When considering HS-6 290373, also note that it doesn't include other halogenated hydrocarbons that may fall under different headings, such as those that are fully fluorinated or brominated. Be clear about the halogen composition in your product.

- What products are classified under HS-6 290373?
- HS-6 290373 covers halogenated derivatives like dichlorofluoroethane (HCFC-141) and HCFC-141b, primarily used in refrigeration and as solvents.
- How can I ensure my product is classified correctly?
- Check the halogen composition of your product. If it contains two or more different halogens, it likely falls under HS-6 290373.
- Are there any restrictions on importing HCFC-141b?
- Yes, HCFC-141b is subject to environmental regulations due to its ozone-depleting potential. Verify compliance with local regulations before importing.
- Can I use HS-6 290373 for products with only one halogen?
- No, if your product contains only one type of halogen, you should classify it under HS-6 290371 instead.
- What are common uses for halogenated hydrocarbons?
- They are commonly used as refrigerants, solvents, and blowing agents in various industrial applications.
- How do I find the right HS code for my chemical product?
- Identify the chemical structure and halogen composition, then consult the HS code listings to find the most accurate classification.
- What should I do if I'm unsure about the classification?
- Consult with a customs broker or trade specialist who can provide guidance based on your product's specifications.
- Is there a difference between HCFC-141 and HCFC-141b?
- Yes, while both are dichlorofluoroethanes, they may have different applications and regulatory requirements. Ensure you classify them correctly.
