HS-4 · Heading
2929 — Nitrogen-function compounds, n.e.c. in chapter 29
Chapter 29: Organic chemicals
Plain-language overview
Use HS-4 2929 when importing nitrogen-function compounds that do not fall under specific categories in chapter 29. For instance, if you're shipping a chemical like a carbamate used in agricultural applications, this heading may apply, particularly if it doesn't fit into other defined subcategories.
When deciding between HS-6 292910 and HS-6 292990, consider whether your product is an isocyanate. If your shipment includes a compound like toluene diisocyanate, classify it under 292910. However, if your nitrogen compound is not an isocyanate, such as a simple amine, use 292990.
Understanding the distinction between these two subheadings is crucial. Isocyanates are reactive and used in making foams and coatings, while other nitrogen-function compounds might serve different roles, like fertilizers or pharmaceuticals. Ensure you identify the specific use of the compound to select the correct code.

- What types of products fall under HS-4 2929?
- HS-4 2929 includes nitrogen-function compounds not specifically classified elsewhere in chapter 29, such as isocyanates and other nitrogen-based chemicals.
- How do I know if my product is an isocyanate?
- Isocyanates are typically reactive compounds used in manufacturing foams and coatings. If your product fits this description, classify it under HS-6 292910.
- Can I use HS-6 292990 for all nitrogen-function compounds?
- HS-6 292990 is for nitrogen-function compounds that are not isocyanates. Ensure your product does not react like an isocyanate before using this code.
- What should I consider when importing nitrogen-function compounds?
- Consider the specific use and chemical structure of your product to determine the correct HS code. This ensures compliance with customs regulations.
- Are there any special regulations for importing isocyanates?
- Yes, isocyanates may be subject to stricter regulations due to their hazardous nature. Check local regulations and safety guidelines before importing.
