AI-Powered supplier vetting
SummaryTianjin Xinruifeng Fastener Manufacturing Co., Ltd. is identified as a combined company engaged in fastener manufacturing, sales, wholesale, equipment-related activities, and import/export. The supplier reports broad product coverage, in-house heat treatment, design and development experience, customization and ODM services, and annual production capacity of up to 20,000 tons. It states that it holds CE certification for drywall screws and receives regular SGS factory audits. Service procedures exist for corrective actions and complaint handling, with records, while service-capability procedures lack records. The supplier reports OEM service for well-known brands and domestic supply to Xinfangsheng, but no SDK is available. Financial and sustainability records are referenced by year, but the provided information does not establish their quality or adequacy. Customer examples and export markets are disclosed, although specific customer performance evidence is limited.
Supplier typeThe supplier is described as Tianjin Xinruifeng Fastener Manufacturing Co., Ltd. and as a combined company. Its stated scope includes fastener and hardware manufacturing, sales, wholesale, equipment activities, and import/export, indicating an integrated manufacturing and trading profile rather than a pure distributor.
CertificationsThe supplier explicitly states that it holds CE certification for drywall screws and that SGS conducts regular factory audits. This provides direct evidence of certification and external audit activity, although certification coverage beyond drywall screws is not stated.
After-Sales capabilityThe supplier has clear procedures with records for corrective and preventive actions and for handling customer complaints effectively. It also claims 24-hour online service, while its written service-capability procedures have no records; therefore, the available evidence supports complaint and corrective-action capability but not fully documented service-system execution.
R&D capabilityThe supplier reports R&D capability, new products during the past year, design and development experience, and multiple design-service options. However, it explicitly has no available SDK, so the evidence supports product and customization development but not SDK-based innovation support.
Production capacityThe supplier states that it has in-house heat treatment, professional technical and production experience, a broad fastener product range, and annual production capacity of up to 20,000 tons. These statements directly support substantial manufacturing capability and delivery capacity.
Customization capabilityThe supplier offers customization from samples and designs, full and minor customization, flexible customization, and ODM services. It also claims experience in designing and producing products, providing explicit evidence of broad customization capability.
Client casesThe supplier reports OEM service for well-known brands, identifies Xinfangsheng as a domestic exclusive-supply customer, and states that customers are located globally, with Russia and India as leading markets. These are identifiable customer and market references, although no independently verified case details or performance metrics are provided.
