HS code · 6-digit subheading

HS Code 2924.29 – 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

HS code 2924.29 is the 6-digit subheading for 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. It is used for caprolactam, N-vinyl-2-pyrrolidone, hydantoin, cyclic urea derivatives and specific pharmaceutical intermediates.

What HS 2924.29 covers

This HS code encompasses a broad range of cyclic amides and cyclic carbamates, along with their derivatives, excluding specific compounds like ureines and alachlor. These complex organic chemicals are vital intermediates and active ingredients across several industries. Pharmaceutical companies import and export these for synthesizing drugs, while agrochemical firms use them in pesticides and herbicides. Additionally, they serve as monomers or additives in the polymer industry. Key aspects of trade involve stringent quality control, compliance with chemical safety regulations, and the need for specialized handling due to their diverse chemical properties and applications. The market is driven by innovation in drug discovery and material science, with a focus on high-purity compounds.

Codes often confused with 2924.29

Common mistake. This code can be confused with other nitrogen-function compounds in Chapter 29, particularly acyclic amides (292419) or specific heterocyclic compounds (2933, 2934) if the cyclic structure is part of a larger ring system.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
