HS Code 2912.29 – Aldehydes; cyclic, without other oxygen function, other than benzaldehyde
HS code 2912.29 is the 6-digit subheading for aldehydes, cyclic, without other oxygen function, other than benzaldehyde. It is used for cyclohexanecarboxaldehyde, phenylacetaldehyde, cinnamaldehyde, citronellal and perillaldehyde.
What HS 2912.29 covers
This HS code encompasses a diverse range of cyclic aldehydes, excluding the more specific benzaldehyde (291221). These compounds are vital building blocks in organic synthesis, finding applications across various industries due to their unique chemical structures and reactivity. Importers are typically chemical manufacturers, pharmaceutical companies, and producers of specialty chemicals who require these specific aldehydes for their synthesis processes. Exporters are often large-scale chemical producers or specialized fine chemical companies. The trade in these "other" cyclic aldehydes is characterized by smaller volumes compared to commodity chemicals but higher value, driven by specific industrial needs. Key considerations include purity, isomer specificity, and compliance with regulatory standards, especially for pharmaceutical or agrochemical intermediates. Their demand is often tied to innovation in new materials, drugs, and advanced chemical processes.

Codes often confused with 2912.29
Common mistake. This code is often confused with 291221 if the specific cyclic aldehyde is benzaldehyde, or with 291249 if the aldehyde has additional oxygen functions like ethers or phenols.
Top exporters and importers of HS code 291229, 2025
In 2025, the largest exporter of HS code 291229 in UN Comtrade data was China, with 18% of world exports; the largest importer in UN Comtrade data was the United States, with 18% 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).
