2921 — Amine-function compounds

Chapter 29: Organic chemicals

Plain-language overview

Use HS-4 2921 when importing amine-function compounds, such as methylamine or ethylenediamine. These compounds are crucial in various applications, including pharmaceuticals and agriculture. For instance, if you're bringing in methylamine in bulk for chemical synthesis, this heading will guide you to the correct classification.

When deciding between the HS-6 lines, consider the specific type of amine you are importing. For example, HS-6 292111 covers acyclic monoamines like methylamine, while HS-6 292121 is for acyclic polyamines like ethylenediamine. If your product is a derivative or a specific salt, you may need to look into the detailed descriptions under each subheading.

If your product is an aromatic amine, you’ll want to differentiate between various types. For example, HS-6 292141 includes aniline and its salts, while HS-6 292143 focuses on toluidines. Understanding these distinctions is key to ensuring compliance and avoiding classification errors.
