Diethylene Glycol
Diethylene glycol (DEG) is an acyclic diol formed by two ethylene glycol units linked by ether bonds, used as a building block in unsaturated polyester resins, classified under HTS 2905.39.90.00. Despite ether linkages, its primary diol nature prevails.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by ether characteristics
Ether-dominant nomenclature could shift to acetal/ether headings.
If antifreeze preparations
Retail antifreeze mixtures containing DEG classify as Chapter 38 preparations.
If erroneous ethylene glycol identification
Misidentification during inspection leads to principal diol subheading.
