HS Code 2912.19 – Aldehydes; acyclic, without other oxygen function, n.e.c. in item no. 2912.1

HS code 2912.19 is the 6-digit subheading for aldehydes, acyclic, without other oxygen function, n.e.c. in item no. 2912.1. It is used for butyraldehyde, valeraldehyde, caproaldehyde, isobutyraldehyde and crotonaldehyde.

What HS 2912.19 covers

This HS code is a residual category for acyclic aldehydes without other oxygen functions, excluding methanal (formaldehyde) and ethanal (acetaldehyde). It encompasses a wide variety of aldehydes that serve as critical intermediates in the synthesis of pharmaceuticals, agrochemicals, flavors, and fragrances. These compounds are traded by a mix of specialty chemical manufacturers and larger chemical distributors globally. Their diverse applications range from industrial solvents and plasticizers to precursors for complex organic molecules. The trade in these 'other' acyclic aldehydes is dynamic, driven by specific industry demands for tailored chemical properties, making it an important segment within the fine and specialty chemical markets.

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).
