HS Code 2913.00 – Aldehydes; halogenated, sulphonated, nitrated or nitrosated derivatives of products of heading no. 2912
HS code 2913.00 is the 6-digit subheading for aldehydes, halogenated, sulphonated, nitrated or nitrosated derivatives of products of heading no. 2912. It is used for chloral hydrate, bromal, nitrobenzaldehyde, sulfobenzaldehyde and trichloroacetaldehyde.
What HS 2913.00 covers
This HS code covers a specialized category of aldehydes that have undergone further chemical modification through halogenation, sulfonation, nitration, or nitrosation, derived from the compounds classified under heading 2912. These derivatives are typically high-value, niche chemicals used as intermediates in the synthesis of pharmaceuticals, agrochemicals, dyes, and other advanced materials. Importers are often specialized chemical manufacturers, pharmaceutical research and development companies, and fine chemical producers who require these specific functionalized aldehydes for complex synthesis pathways. Exporters are generally fine chemical companies or R&D-focused chemical producers with advanced synthesis capabilities. Trade in these derivatives is characterized by stringent purity requirements, often custom synthesis, and adherence to intellectual property rights. Their demand is driven by innovation in new drug discovery, advanced material science, and the development of more effective agrochemicals.

Codes often confused with 2913.00
Common mistake. This code can be confused with the unmodified aldehydes of heading 2912 if the specific halogenated, sulfonated, nitrated, or nitrosated derivative is not clearly identified. It might also be mistaken for other halogenated or nitrated organic compounds (Chapter 29) if the aldehyde function is overlooked.
Top exporters and importers of HS code 291300, 2025
In 2025, the largest exporter of HS code 291300 in UN Comtrade data was China, with 57% of world exports; the largest importer in UN Comtrade data was India, with 34% 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).

What products fall under HS code 291300?
Chloral hydrate, Bromal, Nitrobenzaldehyde, Sulfobenzaldehyde, Trichloroacetaldehyde, 4-Nitrobenzaldehyde, 2-Chlorobenzaldehyde
What are common misclassifications for HS code 291300?
This code can be confused with the unmodified aldehydes of heading 2912 if the specific halogenated, sulfonated, nitrated, or nitrosated derivative is not clearly identified. It might also be mistaken for other halogenated or nitrated organic compounds (Chapter 29) if the aldehyde function is overlooked.
Which countries are the top exporters of goods under HS code 291300?
In 2025, the top exporters of HS code 291300 in UN Comtrade data were China ($40M, 57% of world exports), India ($21M) and Germany ($4.3M). World exports came to about $70M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of goods under HS code 291300?
