Morning Market Brief: Diethylene Glycol

Published on 2026-09-30

1. Key Focus Points

  1. Mediators such as Qatar continue to push for US-Iran peace talks. Combined with the recovery of Saudi crude oil supply, international oil prices have declined.
  2. The average operating rate of domestic unsaturated resin (UPR) plants this week was 33%, an increase of 0.5% from the previous period.
  3. On September 28, total shipments from two storage zones in Zhangjiagang reached 536 tons, an increase of 137 tons compared to the daily average during the Mid-Autumn Festival holiday. As of now, inventory at the Changjiang International and Fubao storage zones stands at 0.25 ten-thousand tons (2,500 metric tons).

Core Logic: International oil prices have returned to a downward trend. Bulk commodity movements are mixed. Diethylene glycol (DEG) demand remained moderate before the holiday, leading to a weakening market.

2. Price Table

  3. All RMB prices listed above are tax-inclusive spot delivery prices.
  4. The change rate represents the period-over-period percentage change.

3. Market Outlook

According to Chempricehub news on September 30: On the last trading day before the holiday, DEG is expected to continue its weak performance. Market participants aim to stabilize prices and clear out remaining stock to wrap up operations. Most traders are waiting for post-holiday arrivals of shipped cargo before making moves. Participation is primarily driven by rigid end-user demand.

    With crude falling and DEG demand staying weak pre-holiday, I see margin pressure building despite lower feedstock costs. The slight UPR utilization bump helps, but low port inventories suggest limited downstream pull. T..
