AI-Powered supplier vetting

SummaryKeep Promise Global (Xiamen) Holding Limited is a China-based limited trading company established in 2021, focused on valves and reporting 10 employees. It states that it offers minor and flexible customization, OEM/ODM production, technical support, and a one-month order fulfillment time in both peak and off-peak seasons. However, the provided records show no available SDK, no management-system certification, no written corrective-action or complaint-handling procedures, and zero quality-control testing equipment. Financial records are indicated for 2022–2024, but no financial results or financial condition are provided. The supplier has an audit record by TUV Rheinland, but the stated evaluation result is 0, with no interpretation supplied. No customer cases or customer references are documented.

Supplier typeThe supplier is identified as a limited company and trading company headquartered in Xiamen, Fujian, China, with 10 employees and no stated affiliation with a larger company group. Its stated business scope includes general trading activities, while valves are identified as its primary product.

CertificationsNo supplier management-system certifications are recorded. Although a TUV Rheinland audit is listed with dates from December 8, 2025 to December 7, 2026, the audit evaluation result is stated as 0 and no certification or positive audit interpretation is provided.

After-Sales capabilityThe supplier describes technical support, but it has no written procedures or records for corrective and preventive actions or customer complaint handling. This directly indicates a documented after-sales process deficiency, despite the general service claim.

Production capacityThe supplier is classified as a trading company, and its product scope identifies valves, but no manufacturing capacity is documented. Production-control evidence is weak: quality-control testing equipment is listed as 0, while quality assurance and traceability status are unknown; the stated order lead time is one month in both peak and off-peak seasons.

Customization capabilityThe supplier explicitly reports minor customization and flexible customization capabilities and describes customized solutions and OEM/ODM production for valves. These statements provide direct evidence of customization availability, although they do not quantify the technical scope or manufacturing ownership of the service.
