For purchasers, evaluating a persulfate supplier hinges on two core dimensions: consistent long‑term supply and stable product quality. Production capacity ensures adequate supply, while quality control guarantees reliable performance. The two factors complement each other. Focused on the persulfate sector for years, Fujian Zhanhua Chemical has continuously built strengths in both capacity and quality control, emerging as a qualified option among persulfate suppliers for many downstream manufacturers.

Ⅰ. Production Capacity as the Foundation: Large‑Scale Production Lines Support Stable Supply Reliable supply capacity is not merely a verbal commitment, but built upon tangible production capacity. The persulfate product portfolio mainly includes ammonium persulfate, sodium persulfate and potassium persulfate. Featuring stable oxidation performance and favorable storage characteristics, these products are widely applied in industrial sectors including PCB etching, chemical synthesis, environmental desulfurization and denitrification, and new energy battery material recycling.

Fujian Zhanhua Chemical offers a complete product range covering the three major categories. Current annual capacities stand at 75,000 tons for ammonium persulfate, 50,000 tons for sodium persulfate and 12,000 tons for potassium persulfate, delivering prominent large‑scale production advantages. The three production lines operate in synergy with flexible allocation and complementary capacity, meeting customers’ multi‑variety and bulk procurement requirements. Both bulk industrial raw materials and fine chemical customized demands can be fulfilled under unified production and quality inspection standards.

For downstream enterprises, such capacity scale translates to stable supply assurance and flexible delivery schedules. Multi‑product demands can be fulfilled by a single supplier, cutting coordination costs from dealing with multiple vendors and facilitating unified quality standard management. It also effectively mitigates the risk of supply shortage during peak stocking periods, providing solid support for continuous production. Robust capacity layout forms the foundation for Zhanhua Chemical’s long‑term service to downstream markets.

Ⅱ. Quality Control as the Safeguard: Full‑Process Inspection Ensures Consistent Quality While capacity defines output volume, quality control determines whether each batch of goods can be safely adopted by customers. Zhanhua Chemical has established a rigorous full‑process quality inspection system, implementing checks from incoming raw material testing, in‑process production monitoring to finished product inspection before delivery. Quality monitoring points are set at key working procedures. Finished products are warehoused only after passing batch‑by‑batch testing, with Certificate of Analysis (COA) provided for customers to verify upon arrival, enabling traceable records for every batch.

Beyond inspection procedures, the company has obtained certifications including ISO9001 quality management system, ISO14001 environmental management system and ISO45001 occupational health and safety management system. Standardized management covers quality, environment, occupational health, energy and other dimensions. Quality control does not rely on individual manual experience; documented specifications and records run through daily production for sustained implementation. As a result, every batch of products from Zhanhua Chemical maintains consistent quality performance. Downstream users can reduce repeated adjustment of process parameters caused by batch variations during continuous production, supporting stable operation of downstream production lines.

Ⅲ. Concurrent Capacity Expansion and Quality Control to Reinforce Commitments Zhanhua Chemical is steadily pushing forward the Phase 3 technical renovation and expansion project, which is scheduled to be put into operation successively in March 2028. Upon completion, the total annual capacity will rise to 135,000 tons of ammonium persulfate, 90,000 tons of sodium persulfate and 22,000 tons of potassium persulfate, further elevating supply capacity. Continuous capacity expansion represents the company’s proactive layout and long‑term investment in supply assurance, presenting customers with a clear roadmap of capacity growth.

Capacity expansion is carried out without compromising quality control, with unified product delivery standards maintained. This substantiates the commitment of “long‑term stable supply”. For purchasers, a supplier equipped with sufficient existing output, clear expansion plans and sound quality management system can reliably match raw material supply with the enterprise’s production scheduling over an extended period. Continuous investment in production capacity and long‑term stable quality control mutually validate each other, making it a trustworthy long‑term supplier.

Stable capacity, superior quality and long‑term reliability constitute the core competitive strengths of Zhanhua Chemical. The company leverages mature large‑scale capacity to guarantee prompt delivery, adopts standardized full‑process quality control to secure product quality, and reinforces long‑term supply capability through well‑defined expansion plans. While balancing delivery stability and quality consistency, the enterprise keeps upgrading to provide downstream customers with dependable and sustainable supply of persulfate raw materials.
