Weekly Statistics on China's DOTP Production Volume and Capacity Utilization Rate (November 6–12, 2026)

During the week of November 6–12, 2026, mainland China's DOTP production totaled 45,800 tons, an increase of 4,500 tons from the previous period, representing a week-on-week (WoW) growth of 10.90%. The average weekly capacity utilization rate for operating units stood at 66.58%, rising by 6.44 percentage points compared to the previous week. Several units restarted this week, including Ningbo Xiangda, Ningbo Nanya, and Anhui Litian. Currently, the DOTP unit operating rate has increased to approximately 67%, placing it at a medium-to-high level within the year. While supply increased, new order transactions remained sluggish, leading to a gradual easing of backlog and shipment queues in the DOTP market. (Note: Inner Mongolia Hairun Changsheng adjusted one of its 30,000-ton/year production lines to produce DOTP in late October. Starting November 1, the total annual DOTP industry capacity increased by 30,000 tons, adjusting the total industry capacity coefficient to 3.38 million tons/year.)
