The simultaneous rise across curing agents, resins, pigments, and additives points to broad-based cost pressure throughout the powder coating supply chain. The prevalence of "one order, one price" arrangements suggests that suppliers are reluctant to lock in fixed prices amid rapid market fluctuations.

HAA curing agent posted the sharpest increase, surging 1,400–1,600 RMB/ton, likely driven by tight supply of key raw materials. Epoxy resin followed with a near-1,000 RMB/ton jump, while polyester resin and titanium dioxide also recorded solid gains.

Market participants are advised to monitor upstream feedstock trends closely, as further price adjustments may follow in the coming weeks.
