2909.11.00.00 - Diethyl ether

HTS code 2909.11.00.00 specifically classifies Diethyl ether, also known as ethyl ether. This compound is a volatile, flammable organic liquid belonging to the class of acyclic ethers. Its primary uses include acting as a solvent for fats, oils, resins, and waxes, and historically, as an anesthetic agent. The classification focuses on this single, well-defined chemical entity.

This specific heading is distinguished from its sibling category, 2909.19, which covers "Other" acyclic ethers. While 2909.11.00.00 is limited solely to diethyl ether, 2909.19 encompasses all other acyclic ethers that do not meet the specific description of diethyl ether, such as dimethyl ether or diisopropyl ether. The key differentiator lies in the precise chemical identity of the ether.

As 2909.11.00.00 is a terminal node within the HTS structure, there are no further subcategories to introduce. Classification under this code is dependent on the precise identification of the imported or exported substance as diethyl ether, based on its chemical composition and properties.
