HS-6 · Subheading
292429
Cyclic amides (including cyclic carbamates) and their derivatives; other than the derivatives and salts of ureines, 2-acetamidobenzoic acid (N-acetylanthancillic acid),ethinamate S, and alachlor (ISO) and their derivatives and salts
Heading 2924 — Carboxyamide-function compounds; amide-function compounds of carbonic acid
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 292429 when importing or exporting cyclic amides and their derivatives, such as N-methylpyrrolidone (NMP). This code specifically excludes certain derivatives and salts like alachlor, making it crucial to verify product details before classification.
This code falls under HS-4 2924, which covers carboxyamide-function compounds. If you're dealing with amides that are not cyclic or are derivatives of ureines, you would need to look at a different code, such as HS-6 292421 for straight-chain amides.
Cyclic amides, or lactams, are often used in pharmaceuticals and industrial applications. For instance, caprolactam, used in nylon production, is classified differently under HS-6 292421. Understanding these distinctions helps ensure compliance and correct duty assessments.
When considering HS-6 292429, remember that it includes derivatives of cyclic amides but excludes specific exceptions. Always check if your product is one of the exceptions listed to avoid misclassification.
