HS Code 2926.20 – Nitrile-function compounds; 1-cyanoguanidine (dicyandiamide)
HS code 2926.20 is the 6-digit subheading for nitrile-function compounds, 1-cyanoguanidine (dicyandiamide). It is used for dicyandiamide powder, granular dicyandiamide, technical grade dicyandiamide and electronic grade dicyandiamide.
What HS 2926.20 covers
This code covers 1-cyanoguanidine, more commonly known as dicyandiamide (DCDA). DCDA is a highly versatile chemical used in numerous industrial applications. It serves as a flame retardant, an epoxy resin curing agent, a nitrification inhibitor in fertilizers, and a key precursor in the production of melamine and guanidine salts. Importers are typically manufacturers in the plastics, agriculture, and chemical industries, while exporters are specialized chemical producers. Key aspects of its trade include its role in enhancing material properties, its environmental applications in agriculture for slow-release fertilizers, and its importance as a building block for other significant industrial chemicals. Purity and particle size are often critical specifications.

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).
