Potassium persulfate markets in China advanced in April on firmer downstream Potassium Persulfate demand and tighter Potassium Persulfate supply. Higher electricity tariffs and power rationing raised conversion costs for electro-oxidation cells, curbing full-rate output at large coastal units. Environmental checks kept many inland plants offline, limiting volumes reaching east-coast warehouses. Mid-month restocking by polymer and electronics sectors absorbed inventories, while producers trimmed export allocations to prioritise domestic inquiries, prompting buyers to accept firmer offers to secure April cargos. Demand was broad-based yet uneven across end-uses, sustaining the move. The polymer and resins sector remained resilient, led by acrylic-resin coatings and styrenic-resin adhesives as restocking ahead of campaigns boosted offtake; electronics also contributed strongly as PCB etchers increased purchases ahead of the May manufacturing rush. Water-treatment demand remained steady but modestly supportive. Market dynamics stayed tight as larger coastal operations ran at moderate rates amid higher electricity costs, while inland plants stayed offline. Looking into May, the market is bullish with moderate inventories and variables.
