Since December 2025, China’s organosilicon market has ended an 18-month downward price cycle and entered a phase of gradual recovery. According to the latest data from the China Chemical Information Center, as of late March 2026, the ex-works price of mainstream dimethylcyclosiloxane (DMC) had stabilized around RMB 13,200 per metric ton—up approximately 28% from the low of RMB 10,300 per ton recorded in November 2025. Notably, this rally is not driven by short-term speculation but by a fundamental improvement in supply-demand dynamics.
The core driver behind the price rebound lies in supply-side reforms. In November 2025, led by Hoshine Silicon Industry, 11 major monomer producers convened a meeting of actual controllers and reached a consensus on “coordinated production cuts and price stabilization.” Starting December 2025, they collectively reduced operating rates to below 70%, cutting DMC supply by an estimated 1 million tons annually. This initiative was further supported by the National Development and Reform Commission (NDRC), which issued the Guiding Opinions on Regulating Price Competition in the Basic Chemical Industry in December 2025, explicitly discouraging destructive price wars.
