HS Code for Dimethyl ether

Dimethyl ether (DME) is classified under HS code 2909.19. This classification follows the structure of Chapter 29, which encompasses separate chemically defined organic compounds. Heading 2909 covers ethers, ether-alcohols, ether-phenols, and their halogenated, sulfonated, nitrated, or nitrosated derivatives. Dimethyl ether is an acyclic ether. While diethyl ether has its own specific subheading (2909.11), dimethyl ether falls into the "other" acyclic ethers category under 2909.19. The classification is straightforward for pure dimethyl ether (typically 99% purity or higher). If the product is presented as a liquefied gas mixture intended for use as a fuel, it might be subject to classification in Chapter 27; however, as a pure chemical intermediate or propellant, it remains firmly within 2909.19.

Products Included

• Pure Dimethyl ether (DME)
• Methoxymethane
• Wood ether
• Dimethyl oxide
• DME used as an aerosol propellant

Common Misclassification

The most common misclassification occurs with HS code 2909.11, which is exclusively for diethyl ether. Importers often select the first available acyclic ether code without verifying the alkyl groups. Additionally, dimethyl ether is sometimes incorrectly classified under 2711.19 (liquefied petroleum gases) when used as a fuel additive. However, according to the Chapter 29 legal notes, chemically pure compounds are excluded from Chapter 27. Another error involves 2909.19 being confused with 2905.11 (methanol), which is the primary feedstock for DME production but represents a different functional group (alcohol vs. ether).

FAQ

What is the HS code for Dimethyl ether?

The HS code for Dimethyl ether is 2909.19.

Does the purity of Dimethyl ether affect its HS code?

Yes, to be classified under 2909.19, the dimethyl ether must be a separate chemically defined compound. If it is mixed with other hydrocarbons for use as a fuel, it may be classified under Chapter 27 (Heading 2711).
