HS Code 2909.19 – Ethers; acyclic, and their halogenated, sulphonated, nitrated or nitrosated derivatives, other than diethyl ether
HS code 2909.19 is the 6-digit subheading for ethers, acyclic, and their halogenated, sulphonated, nitrated or nitrosated derivatives, other than diethyl ether. It is used for methyl tert-butyl ether (MTBE), dimethyl ether (DME), isopropyl ether, dipropyl ether and dibutyl ether.
What HS 2909.19 covers
This category encompasses acyclic ethers and their derivatives, excluding diethyl ether. These compounds are incredibly versatile, serving as solvents, chemical intermediates, fuel additives, and components in fragrances and flavors. Key examples include methyl tert-butyl ether (MTBE) used as a gasoline additive, and dimethyl ether (DME) explored as an aerosol propellant and alternative fuel. Companies involved in their trade range from large petrochemical giants to specialty chemical producers and pharmaceutical firms. The trade dynamics are influenced by global energy policies, environmental regulations, and the demand for specific industrial solvents, making purity and specific isomer identification critical for accurate classification and application.

Codes often confused with 2909.19
Common mistake. Often confused with 290911 if the specific ether is diethyl ether, or with cyclic ethers under 290920 due to similar chemical properties but different ring structures.
Top exporters and importers of HS code 290919, 2025
In 2025, the largest exporter of HS code 290919 in UN Comtrade data was China, with 32% of world exports; the largest importer in UN Comtrade data was Mexico, with 15% 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).
