Bio-Based Diethylene Glycol
Bio-based diethylene glycol is chemically identical to petrochemical 2,2'-oxydiethanol but derived from renewable ethylene oxide, with over 50% bio-carbon content verified by 14C testing. It qualifies as a separate chemically defined organic compound under Chapter 29 Note 1(a) and is classified under tariff item 2909.41.00 as an ether-alcohol.
