China’s phosphorus trichloride market remained under pronounced pressure throughout May 2026 as persistent oversupply and subdued downstream demand outweighed temporary feedstock support. While April prices provided the starting point for market activity, attention quickly shifted toward May’s deteriorating fundamentals, particularly the accumulation of inventories and slower procurement from agrochemical and specialty chemical sectors. Phosphorus trichloride producers faced increasing pressure to reduce offers to clear material, despite higher liquid chlorine costs that briefly improved production economics during the middle of the month. Demand from flame retardants, pharmaceutical intermediates, and water-treatment chemicals remained comparatively stable but was insufficient to absorb excess availability. Smooth logistics and uninterrupted operating rates further contributed to comfortable supply conditions across major production hubs. As May progressed, phosphorus trichloride pricing weakened steadily, with sellers prioritizing inventory reduction over margin preservation. Looking ahead, phosphorus trichloride prices are expected to remain under pressure unless downstream demand improves materially or inventories tighten significantly.
