Last updated: July 2026 dataDiethylene glycol (DEG), also traded as digol, is a widely used industrial solvent, humectant, and chemical intermediate for polyester resins, plasticizers, and morpholine production. Canada is the leading US supplier — a supply relationship supported by integrated North American petrochemical infrastructure — with India and China also significant sources. DEG has been the subject of high-profile adulteration incidents in pharmaceutical and food-contact applications globally, so importers supplying downstream industries with purity or food-contact requirements should maintain robust certificate-of-analysis documentation.

Industrial-grade DEG typically meets ASTM or equivalent specifications focused on water content, color, and acidity. For applications where DEG contacts pharmaceutical ingredients or food-contact materials, buyers often require USP-grade or equivalent certificates of analysis confirming the absence of ethylene glycol and other toxic impurities. Importers should obtain and retain these documents as part of their supply-chain due-diligence records.
Chinese-origin DEG may be subject to Section 301 tariffs. Canadian-origin DEG benefits from USMCA treatment, which can significantly affect landed cost calculations when comparing North American versus Asian supply options.
