HS Code 2929.90 – Nitrogen-function compounds; n.e.c. in chapter 29, excluding isocyanates
HS code 2929.90 is the 6-digit subheading for nitrogen-function compounds, n.e.c. in chapter 29, excluding isocyanates. It is used for guanidine hydrochloride, creatine, melamine, urea derivatives (not elsewhere specified) and hydantoin.
What HS 2929.90 covers
This broad HS code covers a diverse range of nitrogen-function organic compounds that are not specifically classified elsewhere in Chapter 29 and are explicitly not isocyanates. This "basket" category includes a multitude of complex organic chemicals, often serving as intermediates in the synthesis of pharmaceuticals, agrochemicals, specialty polymers, and fine chemicals. Given its broad nature, the trade in these compounds is highly fragmented, catering to niche applications across various industries. Major importers are typically countries with sophisticated chemical and pharmaceutical manufacturing sectors, such as the United States, Germany, China, and Japan, where these specialized compounds are used in advanced synthesis. Exporters often include specialized chemical manufacturers globally, with significant contributions from China, India, and European chemical hubs. Key considerations for trade include the specific chemical identity, high purity requirements, and often small batch sizes, reflecting their specialized applications. Regulatory compliance for safety and environmental impact is also a constant factor.

Codes often confused with 2929.90
Common mistake. This code is a residual category and can be easily confused with more specific nitrogen-function compound codes (e.g., 2921 for amines, 2922 for amino-alcohols, 2928 for hydrazine derivatives) if the compound's primary functional group is not precisely identified.
Top exporters and importers of HS code 292990, 2025
In 2025, the largest exporter of HS code 292990 in UN Comtrade data was China, with 26% of world exports; the largest importer in UN Comtrade data was the United States, with 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
