HS Code for Ether

Diethyl ether is classified under HS code 2909.11, which falls within Chapter 29 of the Harmonized System, dedicated to organic chemicals. Heading 2909 specifically covers ethers, ether-alcohols, ether-phenols, and their halogenated, sulphonated, nitrated, or nitrosated derivatives. Within this heading, the code 2909.11 is reserved for diethyl ether, an acyclic ether. The classification is determined by the chemical structure of the substance. As a pure chemical compound or a technically pure product, it must be classified in Chapter 29 rather than as a prepared solvent or a medicament, unless it meets very specific criteria for those chapters. Diethyl ether is a highly volatile and flammable liquid used extensively as a solvent in laboratories and industrial processes. Its classification remains consistent regardless of the intended end-use, provided it is not mixed with other substances in a way that changes its essential character to a preparation of Chapter 38 or a medicament of Chapter 30.

Common Misclassification

Diethyl ether is often confused with other acyclic ethers classified under 2909.19, such as methyl tert-butyl ether (MTBE) or dimethyl ether. It may also be misclassified under 3814.00 if it is part of a complex organic composite solvent mixture. Furthermore, while diethyl ether has medical uses, it is rarely classified under 3004 (medicaments) unless it is put up in measured doses or in forms or packings for retail sale for therapeutic use. Another potential error is 2909.20, which is reserved for cyclanic, cyclenic, or cycloterpenic ethers, whereas diethyl ether is acyclic.

FAQ

What is the HS code for [product]?

The HS code for diethyl ether is 2909.11.

Is diethyl ether regulated for transport?

Yes, while the HS code identifies the chemical for customs, it is also subject to strict hazardous materials regulations (UN1155) due to its high flammability and tendency to form explosive peroxides.
