AI-Powered supplier vetting

SummaryRelong is a China-based manufacturer and service provider focused on water-environment protection machinery. It reports ISO9001:2015 and CE certifications, documented quality, corrective-action, and complaint-handling procedures, and substantial export activity with self-operated import/export rights. Its capabilities include broad customization, ODM, OEM for well-known brands, in-stock service, and approximately one-month lead times in both peak and off-seasons. Innovation evidence includes new products within the past year, five years of R&D engineer experience, and regional technology and innovation awards. Production information is limited to one production line and no valid manufacturing-capacity contract with related subcontractors. No overseas warehouse or showroom, no available SDK, and no Fortune 500 cooperation are reported. Financial information is insufficient for assessment because only years are provided, not financial results.

Supplier typeRelong describes itself as a China-market-based company expanding internationally, engaged in development and manufacturing, installation and commissioning, and marketing and sales services. Its 90% export-sales share, self-operated import/export rights, and Qingdao Port proximity support classification as an export-oriented manufacturer with integrated project and service activities.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CE product-compliance certification. These certifications provide explicit evidence of recognized quality-management and product-compliance credentials.

After-Sales capabilityRelong has documented procedures and records for supplier-service assessment, corrective and preventive actions, and customer complaint handling, and states that quality assurance is present. However, it reports no overseas warehouse or showroom; the evidence supports structured service processes but not comprehensive overseas infrastructure.

R&D capabilityThe supplier reports new products within the past year, ODM services, five years of total R&D engineer experience, and provincial awards for technical innovation, new products, and technology progress. These are explicit indicators of active product development and recognized innovation performance.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, demonstrating a broad stated capability to adapt or develop products to customer requirements.

Client casesRelong reports OEM service for well-known brands and a repeat-buyer preference rate of 50%–80%, indicating established customer relationships. However, it reports no cooperation with Fortune 500 companies and provides no named customers or verifiable case details.
