Morning Market Update: Diethylene Glycol (DEG)

Published on 2026-11-06

I. Key Points

  1. The outlook for US-Iran relations remains uncertain, with the possibility of renewed conflict between the two sides still present. Supply risks have increased, 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 4, total shipments from two storage terminals in Zhangjiagang amounted to 541 tons, an increase of 7 tons compared to the previous day. As of now, inventory levels at Changjiang International and Fubao terminals stand at 11,000 tons.

Core Logic: International crude oil prices turned downward after reaching highs; diethylene glycol (DEG) transactions slowed down; one shipment arrived at the main port, but the resulting inventory buildup was limited.

II. Price List

Category Product Region/Unit Previous Period Price Current Period Price Change Rate (%)
Crude Oil WTI USD/barrel 88.12 90.52 2.72

  4. The change rate represents the period-over-period percentage change.

III. Market Outlook

According to Chempricehub news on November 6: External instability factors are prominent, and the chemical market is closely monitoring these developments. Currently, diethylene glycol (DEG) exhibits a unidirectional trend. Neither bulls nor bears have taken decisive action; most market participants are awaiting forecasts for Middle Eastern shipments, while spot prices fluctuate within a fixed range.

    With UPR operating rates at 34%, downstream demand is weak, keeping DEG margins tight despite rising feedstock costs from crude volatility. I expect prices to range-bound as limited inventory buildup fails to offset slug..
