SummarySIDLEY CHEMICAL CO., LTD. is a Chinese limited company established in 2005, operating in Shandong and focused on construction chemicals. The supplier reports customization and ODM capabilities, recent new-product development, OEM service for well-known brands, and documented procedures for supplier service capability, corrective and preventive actions, and customer complaints. Production information indicates two production lines and substantial stated capacities across cellulose products, redispersible polymer powder, and calcium formate, although the reported capacity figures differ between slices. Overseas service support includes agents or branches and participation in the Eurocoat Exhibition, but no overseas warehouse or showroom is reported. Financial records are identified for 2023–2025, but no usable financial performance details are provided. A BV audit is listed with validity from April 20, 2026 to April 19, 2027 and an evaluation result of 0; the meaning of this result is not explained.

It also supports overseas services through agents or branches and offers service coverage in Pakistan, but it has no overseas warehouse or showroom.
