Morning Market Briefing on Diethylene Glycol (DEG) (September 20, 2026)

I. Key Focus Points

1. Expectations for the repair of Saudi Arabian oil pipelines have improved, coupled with signs of easing tensions in the Middle East, leading to a decline in international crude oil prices.
2. This week, the average operating rate of domestic unsaturated polyester resin (UPR) plants was 33%, an increase of 0.5 percentage points from the previous period.
3. On September 17, total shipments from two tank farms in Zhangjiagang amounted to 170 tons, a decrease of 330 tons compared to the previous day. As of now, combined inventory at Changjiang International and Fubao tank farms stands at 2,600 tons.

Core Logic: Bulk commodity prices follow crude oil fluctuations; diethylene glycol (DEG) is experiencing a one-way trend; market participants are closely monitoring pre-holiday shipment activities.

1. All product prices refer to national standard premium grade products.
2. Crude oil prices are in USD/barrel; other three products are priced in CNY/ton.
