HS Code 2933.69 – Heterocyclic compounds; containing an unfused triazine ring (whether or not hydrogenated) in the structure, others excluding melamine
HS code 2933.69 is the 6-digit subheading for heterocyclic compounds, containing an unfused triazine ring (whether or not hydrogenated) in the structure, others excluding melamine. It is used for atrazine, simazine, cyanuric acid, trimetazidine and anastrozole.
What HS 2933.69 covers
This HS code covers a diverse array of heterocyclic compounds that contain an unfused triazine ring in their structure, specifically excluding melamine. These "other" triazine compounds are highly versatile and find applications across various industries, including agriculture, pharmaceuticals, and specialty chemicals. Many are used as herbicides (e.g., atrazine, simazine), dyes, optical brighteners, or as intermediates in the synthesis of more complex molecules. The international trade in these compounds is driven by the agricultural sector's demand for crop protection chemicals and the chemical industry's need for specialized building blocks. Key exporters include countries with advanced chemical synthesis capabilities and significant agricultural chemical production, such as China, India, Germany, and the United States. Importers range from agrochemical formulators to pharmaceutical companies and textile manufacturers globally. Trade considerations include environmental regulations for agrochemicals, purity requirements for pharmaceutical intermediates, and safe handling protocols. The market is influenced by agricultural cycles, regulatory changes concerning specific chemicals, and ongoing research into new applications for triazine derivatives.

Codes often confused with 2933.69
Common mistake. This is a residual category for triazine compounds. It's often confused with 293361 (melamine) or other specific chemical codes if a triazine derivative has a more precise classification elsewhere, especially if it's a well-known API.
Top exporters and importers of HS code 293369, 2025
In 2025, the largest exporter of HS code 293369 in UN Comtrade data was China, with 53% 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).
