How Rising Production Costs Are Influencing China’s Potassium Persulfate Market in July 2026

Potassium Persulfate prices in China strengthened in July 2026 by 4.1%, supported by firmer feedstock costs and gradually improving seasonal demand. The market recovered from the subdued procurement environment seen in June, when buyers held sufficient inventories and downstream operating rates remained restrained. On the demand side, demand from acrylic sheets, PVC paste resins and polymerisation-initiator applications showed signs of improvement as converters gradually increased production following the summer slowdown. Producers consequently gained greater pricing confidence and were able to pass part of the higher manufacturing costs onto buyers. On the supply side, Sulphuric Acid prices rose 4.16%, increasing conversion costs and encouraging manufacturers to defend margins through firmer offers. Meanwhile, stable availability of potassium hydroxide and a comfortable domestic supply limited the extent of the increase. Regular production and the absence of major maintenance shutdowns ensured adequate availability, while steady exports to Asian markets helped manage domestic inventories.

Demand for Potassium Persulfate improved across several downstream applications during July, although recovery remained uneven. Acrylic sheet, PVC paste resin and polymerisation-initiator consumption strengthened as converters gradually increased production, while construction-related coatings demand remained relatively restrained. PCB etching requirements continued to provide a stable base, although they did not generate significant incremental buying. Mining-flotation demand remained broadly neutral, while synthetic rubber and acrylic producers began preparing for stronger autumn manufacturing activity. Automotive and consumer-goods supply chains also showed early signs of inventory rebuilding, supporting procurement of polymer intermediates and providing a more constructive demand environment for Potassium Persulfate.

Supply conditions continued to remain comfortable in China during July. Potassium Persulfate manufacturers largely maintained stable operating rates, with no significant maintenance shutdowns disrupting availability. Domestic producers continued to supply the market, while exports to destinations including India and Vietnam remained supported by normal coastal logistics. Inland inventories were sufficient to meet immediate requirements, limiting the urgency of spot procurement and preventing sellers from gaining substantial pricing power. Sulphuric Acid rose 4.16% during July, creating a cost-based floor beneath Potassium Persulfate offers, while potassium hydroxide availability remained stable and helped prevent a broader escalation in manufacturing costs.

Looking ahead to August, the Potassium Persulfate market is expected to remain moderately firm as seasonal procurement improves and higher feedstock costs continue to influence seller pricing. Downstream acrylics, PVC paste resin, synthetic rubber and polymer-related industries could gradually increase operating rates ahead of the autumn manufacturing cycle, while pre-holiday inventory preparation may provide additional support. At the same time, ample Chinese production capacity and adequate inventories are likely to limit the upside. Export demand should remain an important outlet for domestic supply, although any deterioration in overseas buying or logistics could encourage inventory accumulation. Consequently, Potassium Persulfate prices may continue to receive support from Sulphuric Acid costs and improving downstream activity, but the market is unlikely to experience a severe supply-driven squeeze.
