In mid-October 2026, China’s diethylene glycol (DEG) market registers a mild upward trend amid changing supply and demand fundamentals. According to industry tracking data, port inventories of DEG continue the destocking cycle. The reduction of stored cargo at major coastal ports has eased previous inventory pressure and delivered bottom support for domestic spot quotations.

Downstream industries including unsaturated polyester resin, antifreeze agents and plasticizers have started restocking on a need basis. Manufacturers of antifreeze and resin products place regular orders for DEG raw materials, supporting market trading activity. Nevertheless, downstream buyers remain prudent and mostly adopt just-in-time purchasing strategies instead of large-scale stockpiling, which limits sharp price surges in the short run.

From the global perspective, several overseas DEG production units have entered scheduled maintenance, resulting in tightened overseas available cargo. Overseas suppliers have raised their DEG offers accordingly. Buying inquiries from Southeast Asia and the Middle East have grown notably, as overseas industrial buyers actively source qualified Chinese DEG cargo. China remains a reliable source for industrial-grade diethylene glycol for Asian markets.

Market participants hold mixed views for the near-term outlook. The positive factors include sustained port destocking and overseas plant shutdowns that underpin spot prices. On the other hand, downstream demand recovery is not strong enough to drive a continuous bullish rally. Industry analysts forecast that the DEG market will maintain a steady-to-strong trend with limited fluctuation range in the coming two weeks. Buyers are advised to keep track of port inventory shifts, downstream resin demand and the restart schedules of overseas maintenance facilities.
