AI-Powered supplier vetting

SummaryZhengzhou Grace Machinery Equipment Co., Ltd. is a China-based limited company in Henan engaged in industrial equipment and components, with stated trading and manufacturing/factory activities. Its product range covers multiple centrifuge and filter-press types. The supplier reports ISO 9001 and CE certification and has an active CTI audit record, although the stated audit evaluation result is 0. Customization and ODM services are available, and OEM service for well-known brands is reported, but no new products were developed in the past year and no SDK is available. Quality and service controls show significant documentation gaps: no written corrective-action or complaint-handling procedures, unknown quality-assurance and traceability status, zero listed quality-control test equipment, and no written supplier-service assessment procedure. The supplier states customer-focused service and provides some supplier names, but the evidence does not establish specific customer cases. The reported employee count...

Supplier typeThe supplier is identified as a limited company in China and is described as a trading company, manufacturer/factory, and group corporation, although another record states it is not part of a larger company group. It operates in industrial equipment and components and reports two employees.

CertificationsThe supplier reports CE certification and ISO 9001 certification. A CTI audit record is shown as active from January 4, 2026 to January 3, 2027, but the audit evaluation result is recorded as 0, so the certification and audit evidence should be interpreted with that qualification.

After-Sales capabilityThe supplier has no written procedures or records for corrective and preventive actions, customer complaints, or effective service-capability assessment. It lists two qualified service suppliers and provides some supplier names, but these limited records do not demonstrate a controlled after-sales process.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, as well as ODM service. These statements directly support broad customization availability.
