AI-Powered supplier vetting

SummaryJiaxing City Qunbang Hardware Co., Ltd. is identified as a limited trading company supplying fasteners, including bolts, nuts, thread rods, washers, and related products. It reports more than 10 production lines, stated bolt and nut output, broad export-market coverage, and access to Shanghai and Ningbo ports. The supplier has documented procedures and records for corrective/preventive actions, complaint handling, supplier approval, and service-capability assessment. It provides 3D software design, ODM, and customization from designs or samples, and reports OEM service for known brands. However, no certification information is provided, overseas showrooms or agents are absent, no offline trade-show participation is reported, and recent new-product activity, environmental assessment, and fire-drill status are either negative or unknown. Financial records are referenced for multiple years, but the provided information does not establish financial strength.

Supplier typeThe supplier is explicitly classified as a limited trading company. Its stated business scope covers hardware, fasteners, plastic products, molds, and import/export activities, while its company description also presents production, design, sales, and after-sales functions.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions, customer complaints, approved-supplier updates, and service-capability assessment. It is located near Shanghai and Ningbo ports, but reports no overseas showroom, overseas agent or branch, and no offline trade-show participation.

R&D capabilityThe supplier provides 3D software design, has CAD capability, reports one R&D patent and one registered trademark, offers ODM services, and has an available SDK. Conversely, it reports no new products in the previous year and no private-mold capability, indicating documented but limited evidence of ongoing innovation.

Production capacityThe supplier reports more than 10 production lines, annual bolt output of 4,000 tons and nut output of 5,000 tons, with off-peak lead time within 15 working days. Its stated product range and proximity to Shanghai and Ningbo ports further support operational and export capability.

Customization capabilityCustomization from customer designs and samples is explicitly available, together with 3D software design, ODM services, OEM service for known brands, CAD capability, and SDK availability. The absence of private-mold capability limits the documented customization scope but does not negate the stated services.
