Morning Market Brief for Diethylene Glycol (DEG)

Published on 2026-10-09

I. Key Focus Points

  1. Continued instability in the Middle East, combined with hurricane-induced shutdowns of some offshore U.S. oil wells, has driven up international crude oil prices.
  2. The average operating rate of domestic unsaturated polyester resin (UPR) plants this week was 28%, a decrease of 5 percentage points from the previous period.
  3. Total shipments from the two Zhangjiagang storage terminals during September 30–October 7 amounted to 514 tons, averaging 64.25 tons per day during the holiday. As of now, inventory at the Changjiang International and Fubao terminals stands at 8,300 tons.

Core Logic: Inventory rose due to vessel arrivals; traders returned actively after the holiday, and downstream buyers gradually entered the market.
