Three new diethylene glycol (DEG) plants are planned to be commissioned domestically in 2026, including BASF-Zhanjiang with an annual capacity of 80,000 tons, Sino-Saudi Gulei with 100,000 tons/year, and Huajin-Aramco with 40,000 tons/year, totaling 220,000 tons. PriceSeek's analysis of DEG assigns a bearish score of -1.5. The article notes that three new DEG plants are planned domestically in 2026, with a total additional capacity of 220,000 tons/year, which will significantly increase market supply. The rise in supply may shift the supply-demand balance toward a looser state, exerting downward pressure on spot prices, with a high risk of price declines. Given the substantial scale of the new capacity, it may accelerate inventory accumulation, leading to a relatively clear bearish rating (-1.5).
