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.
