China's ammonium persulfate market strengthened sharply through April 2026, driven by robust ammonium persulfate export demand, higher power costs, and regulatory checks tightening availability. Early April saw coal-fired electricity tariffs rise, lifting cash costs for ammonium persulfate producers; mid-month inspections in Jiangsu briefly reduced inland ammonium persulfate capacity; and late-month export orders from adhesives and electronics formulators accelerated shipments. Producers operated near nameplate with lean inventories ahead of summer tariffs, leaving buyers scrambling to secure allocations for domestic projects and replenish international safety stocks. The net effect was a decisive upward repricing of FOB Shanghai offers. Demand from adhesives and electronics emerged as the primary impulse, while coatings and latex provided steady, supportive pull. Overseas adhesives formulators and electronics buyers tightened ammonium persulfate export allocation, underpinning firmer FOB Shanghai offers. Coatings and latex remained restrained. Market indicators pointed to further upside in the near term, supported by export strength, inland outages, lean inventories, and higher power and costs. Risks include feedstock cost volatility and ammonium persulfate capacity recovery delays.
