Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If monomethyl ether of shorter chain like diethylene glycol
Specific monoalkyl ethers of diethylene glycol have dedicated statistical suffixes.
If for brake fluid formulations containing this compound
Hydraulic brake fluids classified as chemical preparations in Chapter 38 regardless of principal component.
If imported as higher alcohol without prominent ether function
Alcohol priority over ether if hydroxyl group dominates chemical character.

Import Tips & Compliance
ā¢ Include CAS number (34590-94-8) and purity certificates (>99%) to distinguish from mixtures
ā¢ Declare flash point and vapor pressure data for proper hazmat shipping classification
ā¢ Verify not sulfonated/nitrated derivatives which may shift to different subheadings
