Morning Market Insight: Diethylene Glycol (DEG)

Published on 2026-11-12

I. Key Focus Points

  1. The Middle East situation remains unstable, and the prospects for US-Iran negotiations are unclear, leading to a rise in international crude oil prices.
  2. This week, the average operating rate of domestic unsaturated polyester resin (UPR) plants was 34%, a decrease of 1% from the previous period.
  3. On November 10, total shipments from two tank farms in Zhangjiagang amounted to 545 tons, a decrease of 156 tons compared to the previous day. As of now, inventory at Changjiang International and Fubao tank farms stands at 13,300 tons.

Core Logic: Although international crude oil prices have continued to decline recently, new vessel arrivals are limited, and spot availability of diethylene glycol (DEG) is tight. Therefore, the probability of a significant market downturn is low.

III. Market Outlook

According to Chempricehub news on November 12: Currently, the supply-demand structure of DEG continues to provide solid support to the market. Fluctuations in crude oil and bulk commodity trends have had a limited impact on the DEG market. However, due to the lack of new directional drivers, the range for price fluctuation is narrow, making it difficult to see effective market movement in the short term.
