Diethylene Glycol (DEG) Market Weekly Outlook

Published on 2026-09-28

I. Key Focus Points

  1. Iran has proposed a seven-day plan to the United States to advance peace negotiations. If accepted by the U.S., this could lead to the full reopening of the Strait of Hormuz and a subsequent decline in international crude oil prices.
  2. This week, the average operating rate for domestic unsaturated polyester resin (UPR) plants was 33%, an increase of 0.5% compared to the previous period.
  3. On September 23, total shipment volume from two tank farms in Zhangjiagang reached 867 tons, an increase of 601 tons from the previous day. As of now, combined inventory at Changjiang International and Fubao tank farms stands at 3,600 tons.

Core Logic: Bulk commodity prices are following fluctuations in crude oil; Diethylene Glycol (DEG) is experiencing a one-way market trend. Market participants are closely monitoring pre-holiday shipping activities.
