HS code for Dicyandiamide: 2926.20
Nitrile-function compounds, 1-cyanoguanidine (dicyandiamide).
Classification of dicyandiamide under HS 2926.20
Dicyandiamide, chemically known as 1-cyanoguanidine, is classified under HS code 2926.20. This classification is governed by the rules of Chapter 29, which encompasses organic chemicals. Within this chapter, heading 2926 is dedicated to nitrile-function compounds. Nitriles are characterized by the presence of a cyano group (-C≡N) attached to a carbon atom. Dicyandiamide fits this description perfectly as it is a dimer of cyanamide. The international community has assigned the specific subheading 2926.20 to this compound due to its high volume of trade and its diverse industrial applications, ranging from its use as a curing agent in epoxy resins to its role as a nitrogen stabilizer in fertilizers. The classification is based strictly on the chemical structure of the molecule. According to the Explanatory Notes to the Harmonized System, for a product to be classified here, it must be a separate chemically defined organic compound, whether or not containing impurities. If the dicyandiamide is mixed with other substances to form a prepared fertilizer, the classification would shift to Chapter 31.

Codes often confused with 2926.20
Common mistake. Dicyandiamide is often confused with HS code 2924.29, which covers other cyclic amides. While dicyandiamide has amide-like characteristics, the nitrile (cyano) group is the determining functional group for classification under 2926. It is also sometimes incorrectly classified under 3102.10 (Urea) when intended for agricultural use, but as a pure chemical, 2926.20 is legally required.
Top exporters and importers of HS 292620 (the code used for dicyandiamide), 2025
In 2025, the largest exporter of HS 292620 (the code used for dicyandiamide) in UN Comtrade data was China, with 67% of world exports; the largest importer in UN Comtrade data was India, with 33% 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).
