AI-Powered supplier vetting

SummaryNingbo Hanyee Metal Product Co., Ltd. is a China-based trading company and sales branch of Sanmen Dingsheng Metal Products Co., Ltd., associated with OEM fasteners, spare parts, and precision components. The supplier reports ISO9001:2015 certification, more than 10 production lines, fewer than five quality-control staff, and one R&D engineer. It offers OEM/ODM products across standard and non-standard bolts, nuts, rivets, washers, fittings, CNC-machined parts, and related components. Export activity is reported, including sales to developed markets, and the company states that inquiries are answered within one hour. Evidence supports customization and production access through its affiliated manufacturer, but the small stated workforce and limited R&D/QC staffing constrain confidence in independent technical and quality depth. Customer evidence is limited to one recorded buyer and one trade transaction.

Supplier typeThe supplier is explicitly identified as a trading company, limited company, and sales branch of Sanmen Dingsheng Metal Products Co., Ltd. The affiliated company is described as the manufacturing entity responsible for production and product development, so Hanyee appears to combine trading and manufacturer-affiliate access rather than operate solely as an independent factory.

CertificationsThe supplier reports holding an ISO9001:2015 management-system certificate. This is explicit evidence of certification, although the provided information does not state the certificate scope, issuing body, or validity period.

Production capacityThe supplier is linked to a manufacturing affiliate described as producing OEM fasteners, spare parts, and precision components; it reports more than 10 production lines and a factory location. These support access to production capacity, but the reported 60.0 m² plant area and fewer-than-five quality-control staff create uncertainty about the scale and depth of directly controlled manufacturing operations.

Customization capabilityThe company explicitly offers OEM and ODM services and handles standard and non-standard bolts, nuts, rivets, washers, CNC machining, fittings, pins, and spare parts. The stated product range and custom-service claims directly support customization capability.
