Water Treatment sourcing in China — what the data shows

This category covers water treatment chemicals and equipment, including disinfectants such as calcium hypochlorite, sodium hypochlorite, and trichloroisocyanuric acid (TCCA), alongside water pumps, centrifugal and swimming pool pumps, sewage treatment equipment, and smart water meters. The mix spans both chemical water treatment products and the pumping and monitoring equipment used in municipal and pool water systems.

30 suppliers are profiled, of which 29 are identified as factories. Tianjin has the largest concentration with 3 suppliers, while Hangzhou has 2, and Zhucheng, Zhoushan, and Zhongshan each have 1. Supplier locations are more dispersed in this category than in most others, without a single dominant production cluster.

ISO 9001 is the most common certification, held by 17 of the 30 suppliers, followed by CE marking (6). Given that this category includes chemical products, REACH compliance (2) is relevant for suppliers exporting to the EU, and KKDIK (2) for the Turkish market. Buyers of water treatment chemicals should request safety data sheets and chemical composition documentation in addition to general certificates, and verify business registration and factory status before ordering.
