AI-Powered supplier vetting
SummaryThe supplier demonstrates broad customization, OEM/ODM service capability, in-stock capacity, and substantial stated production volumes for contactors and circuit breakers. It exports 90% of total sales, has self-operated import/export rights, serves multiple global regions, and has attended the Canton Fair. ISO9001:2015 and CE certification are reported. However, innovation evidence is limited because no new products were reported in the past year and no SDK is available. Quality and service procedures exist but lack written records, while overseas agents, branches, warehouses, and showrooms are absent. Peak-season fulfillment information is inconsistent: one slice states 2–3 months, while others state within 15 workdays or one month. Financial data is represented only by years, so credibility cannot be determined.
Supplier typeThe supplier is an export-oriented manufacturer with self-operated import/export rights, OEM and ODM capabilities, in-stock capacity, and stated production of 500,000 contactors and 1,500,000 circuit breakers. It serves multiple overseas regions but has no overseas agents, branches, warehouse, or showroom.
CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CE product compliance certification. These are explicit certification holdings, although no additional certification details or validity documentation are provided.
R&D capabilityThe supplier offers ODM services and multiple design customization modes, but reports no new products during the past year and no available SDK. This indicates design-service capability without sufficient evidence of recent product innovation.
Production capacityThe supplier reports annual output of 500,000 contactors and 1,500,000 circuit breakers, maintains inventory capability, and states off-peak lead times within 15 workdays in some records. However, peak-season timing is inconsistent, with records ranging from within 15 workdays or one month to 2–3 months.
Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization, and also provides OEM and ODM services, including OEM for well-known brands. This is strong direct evidence of broad customization capability.
