Chloride applications continue to expand, and the supply chain for fertilizer and water treatment raw materials is being improved by leveraging centralized procurement of basic chemical products.

Chloride products, leveraging their diverse physicochemical properties, span four core sectors: fertilizers, water treatment, metallurgy, and fine chemicals. Within a one-stop centralized procurement network for 42 types of chemical raw materials, chlorides form a stable raw material combination with soda ash and sulfates, continuously exploring new application scenarios in traditional industry upgrades and emerging environmental protection fields, leading to steady expansion of the overall market capacity.

Bulk chloride products focus on the market for essential raw materials. Potassium chloride and ammonium chloride serve as core raw materials for fertilizers, supporting the mass production of chlorine-based compound fertilizers. Calcium chloride and magnesium chloride are used as raw materials for water treatment defluorination and antifreeze agents. Industrial-grade aluminum chloride, combined with soda ash, is used to formulate wastewater flocculant additives. Relying on centralized procurement and supply advantages, raw materials go directly from production areas to production workshops, significantly reducing intermediate distribution costs. Fine chlorides are making breakthroughs in new materials. High-purity zinc chloride and anhydrous aluminum chloride are used in the production of catalysts and lithium battery raw materials. Utilizing hydrochloric acid, a byproduct of sulfate production, in conjunction with synthesis processes, low-cost mass production of fine chlorides is achieved, gradually reducing reliance on imports for high-end raw materials.

Downstream industry upgrades are driving new demand. Modern agriculture's policy of reducing fertilizer use is promoting the widespread adoption of controlled-release chlorine-based fertilizers, boosting the procurement of refined chlorides. In water environment management, modified chlorinated flocculants are gradually replacing traditional agents, and projects for river and lake sediment treatment and deep industrial wastewater treatment continue to consume modified chlorinated products. The implementation of green smelting processes in the metallurgical industry is leading to the replacement of highly polluting old-fashioned chlorinated fluxes with environmentally friendly ones, optimizing the industrial chloride consumption structure. Centralized procurement platforms integrate different grades of chloride sources, catering to both large-scale industrial procurement and small-batch customized procurement needs, suitable for various production enterprises of all sizes.

Environmental emission restrictions are forcing the greening of chloride production. The recycling of saline mother liquor and the recovery of by-product hydrochloric acid have become standard processes, accelerating the exit of small chloride workshops without environmental disposal capabilities from the market. Industry development trends indicate that the chloride industry will be deeply integrated with the two major downstream pillar industries of fertilizers and water treatment, working in conjunction with soda ash and sulfate to optimize composite raw material formulations, and continuously investing in the research and development of soil amendment agents and new environmentally friendly water treatment materials, thus opening up long-term growth opportunities for the industry.
