Diethylene Glycol Monobutyl Ether (Butyl Digol)
Diethylene glycol monobutyl ether is a colorless liquid used as a solvent in paints, coatings, and cleaning formulations. It falls under HTS 2909.44.0150 as it is a monoalkyl ether of diethylene glycol ('butyl' alkyl group), chemically defined and not specifically excluded. This ether-alcohol combines ether and alcohol functionalities in its structure.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If monomethyl ether of diethylene glycol
Monomethyl ethers have specific provisions earlier in 2909.43; numerical order places it before 'other'.
If imported as formulated mixture with >70% solvent content
Mixtures of chemicals not chemically defined fall under Chapter 38 prepared binders or mixtures.
If for bulk petroleum-derived solvent blends
Petroleum oils containing these ethers classified by base material in Chapter 27.

Import Tips & Compliance
• Provide detailed chemical analysis (CAS 112-34-5) and purity certificates to confirm classification as a monoalkyl ether of diethylene glycol
• Ensure SDS includes safety data for ether-alcohols; verify no added stabilizers that might shift to note 2(f)
