Weekly Market Outlook for Diethylene Glycol (DEG)

Published on 2026-09-21

I. Key Points

  1. Expectations for the repair of Saudi oil pipelines have improved, coupled with signs of easing tensions in the Middle East, leading to a decline in international crude oil prices.
  2. The average operating rate of domestic unsaturated polyester resin (UPR) plants this week was 33%, an increase of 0.5 percentage points from the previous period.
  3. Total shipments from two tank farms in Zhangjiagang amounted to 454 tons on September 18-19, averaging 227 tons per day. As of now, inventory at Changjiang International and Fubao tank farms stands at 3,200 tons.

Core Logic: Bulk commodity prices are following crude oil fluctuations; diethylene glycol is experiencing a one-way market trend; market participants are focusing on pre-holiday shipment activities.
