AI-Powered supplier vetting

SummaryPuyang Zhongshi Group Co., Ltd. is identified as a Chinese manufacturer established in 1997, focused on casing cementing equipment, float equipment, centralizers, and cementing plugs. The supplier reports a 52,000 m² plant, 10 production lines, annual casing-centralizer output of 200,000 pieces, and exports to multiple global regions. ISO 9001:2015, ISO 14001:2015, and ISO 45001:2016 are stated, while other company information references API certifications. Trade records show shipments associated with buyers in India, Brazil, and Peru, but the records are recent and limited. Evidence supports established manufacturing and export capability; after-sales service, financial credibility, and customization capability remain insufficiently documented.

Supplier typeThe supplier is explicitly classified as a manufacturer and describes itself as producing casing cementing equipment and related oilfield products. It is based in Puyang, Henan, China, and reports that it was established in 1997.

CertificationsThe supplier reports ISO 9001:2015, ISO 14001:2015, and ISO 45001:2016 management-system certificates. It also states that it holds API 5CT, API 6A, API 11AX, and API 11E certificates, although the provided information does not include certificate validity or scope details.

Production capacityProduction capability is supported by a reported 52,000 m² plant, 10 production lines, 9 factories, more than 500 employees, and annual casing-centralizer output of 200,000 pieces. The supplier also states that it can serve broad international markets, with typical lead times of 2–3 months in both peak and off-peak periods.

Client casesThe supplier is associated with buyers or shipments involving VNK Solutions, Smart Welding de Macae Servicos Ltda, and a Peru-related transaction, while also stating exports to more than 30 countries. The evidence indicates international customer exposure, but provides limited detail on completed projects, customer satisfaction, order scale, or repeat business.
