HS Code 2927.00 – Diazo-, azo- or azoxy compounds
HS code 2927.00 is the 6-digit subheading for diazo-, azo- or azoxy compounds. It is used for azobenzene, methyl orange, congo red, sudan I and diazoaminobenzene.
What HS 2927.00 covers
This HS code encompasses organic compounds containing diazo (-N=N-), azo (-N=N-), or azoxy (-N(O)=N-) functional groups. These chemicals are highly significant in various industrial applications, particularly in the dye and pigment industry, where azo dyes constitute the largest class of synthetic dyes. They are also utilized in the production of pharmaceuticals, agrochemicals, and as initiators for polymerization reactions. Countries with large textile, printing, and chemical manufacturing sectors, such as China, India, Germany, and the United States, are major importers, using them as raw materials for their finished products. Exporters often include specialized chemical manufacturers in countries like China, India, and European nations. Key aspects of trade include the specific chemical structure, purity, and stability of these compounds, as these factors directly impact their performance in end-use applications. Regulatory compliance regarding environmental impact and safety is also crucial, especially for dyes and pigments.

Common mistake. Misclassification can occur with other organic dyes and pigments in Chapter 32, especially if the chemical structure (azo/diazo/azoxy) is not clearly identified as the primary defining characteristic.
Top exporters and importers of HS code 292700, 2025
In 2025, the largest exporter of HS code 292700 in UN Comtrade data was China, with 42% of world exports; the largest importer in UN Comtrade data was India, with 8.2% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
