AI-Powered supplier vetting

SummaryShandong Chemic Chemical Co., Ltd. is a China-based limited trading company in Jinan, Shandong, focused on chemical products. It offers a broad range of chemical products and reports annual productivity for sodium formate and calcium formate, but the available information does not establish that it owns production facilities. Service infrastructure is limited: it reports no overseas showroom, overseas agents or branches, or prior offline trade-show participation, although it has service-related procedures and records in some areas. Financial records are identified for 2021–2023, but their contents are not provided. Innovation evidence is mixed: the supplier reports two R&D engineers, a national science and technology progress award, and SDK availability, but no new products launched in the previous year. Customization is limited to minor customization. No customer cases are provided.

Supplier typeThe supplier is consistently identified as a trading company and limited company, located in Jinan, Shandong, China, with chemicals as its commercial focus and 22 employees. The available evidence supports a trading-oriented business classification rather than a confirmed manufacturer classification.

CertificationsThe supplier reports holding one national science and technology progress award. However, no specific certification names, standards, validity periods, or certificate documents are provided, so broader certification coverage cannot be assessed.

After-Sales capabilityThe supplier reports no overseas showroom, overseas agents or branches, or prior offline trade-show participation, and indicates zero countries served overseas. It has a corrective and preventive action procedure with records, while complaint handling has a procedure but no written records; this indicates some internal service controls but limited demonstrated international service coverage.

R&D capabilityThe supplier reports two R&D engineers, one national science and technology progress award, and available SDK capability. However, it launched no new products in the previous year, so the evidence indicates some formal innovation resources but limited recent product innovation.

Customization capabilityThe supplier explicitly reports minor customization capability. This supports limited adaptation of offerings, but no evidence supports extensive or complex customization.
