AI-Powered supplier vetting
SummaryJundasheng Hardware & Electrical Co., Ltd. is a Guangzhou-based fastener manufacturer established in 2003, with integrated production, R&D, and sales activities. The supplier reports ISO9001 and SGS certification, documented corrective/preventive-action and complaint-handling procedures, inventory capability, and customization and ODM services. Its stated product scope includes screws, gaskets, nuts, bolts, and other metal products, with reported production of 4,000 tons for each of these four categories and order fulfillment within 15 workdays in both peak and off-peak periods. However, the supplier does not provide OEM services for popular brands, lacks an available SDK, has no overseas warehouse, showroom, agent, or branch, and has not participated in offline trade shows. Financial credibility cannot be assessed because the supplied financial fields contain only years rather than financial results or supporting metrics. Customer-case evidence is also insufficient.
Supplier typeThe supplier is identified as a Guangzhou-based professional fastener production factory established in 2003, combining manufacturing, research and development, and sales. Its registered business scope also covers metal products, machinery parts, electrical equipment, import/export, and related technical services, indicating a manufacturer rather than a pure trading company.
CertificationsThe supplier states that it has obtained ISO9001 quality management system certification and SGS international certification system certification. These are explicit certification claims supporting quality-system credentials, although no certificate numbers, validity dates, or scope details are provided.
After-Sales capabilityThe supplier has documented procedures and records for corrective and preventive actions and customer complaint handling, and it can provide quotations under FOB, CIF, CFR, and EXW terms. However, it has no overseas warehouse, overseas showroom, overseas agent or branch, and offers overseas service in zero countries, so its documented process capability is stronger than its overseas service network.
R&D capabilityThe supplier reports R&D capability, new products during the past year, and ODM service availability, while its company description identifies R&D as part of its integrated operations. Nevertheless, it reports no available SDK, so the evidence supports product-development capability but not software-development or SDK capability.
Production capacityThe supplier reports in-stock capability, production of 4,000 tons each of screws, gaskets, nuts, and bolts, and order fulfillment within 15 workdays in both peak and off-peak seasons. A weakness is that no valid manufacturing-capacity contract exists with related subcontractors, which may limit reliance on outsourced capacity.
Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, flexible customization, and ODM services. This directly demonstrates broad stated customization coverage.
