AI-Powered supplier vetting

SummaryNingbo Yosec Industrial Co., Ltd. is identified as a China-based trading company and limited company located in Ningbo, Zhejiang, with five employees and a stated establishment date of 2017, although another company description cites 2001. Its offerings center on safes, safe locks, cabinets, and related security products. Evidence indicates ISO9001, CE, and RoHS certifications, export activity across multiple regions, approximately 90% export sales, and a one-month stated lead time in both peak and off-peak periods. Production information is inconsistent: one slice states a 115.0 m² manufacturing plant and two production lines, while another claims a 33,000 m² production site. The supplier reports engineering capability for customer-specific metal products, but only one year of R&D-engineer experience is stated. Customer markets and sales-network countries are listed, but specific verified customer cases are not provided.

Supplier typeThe supplier is explicitly classified as a trading company, with a limited-company structure and headquarters in Ningbo, China. Its stated product scope includes safes, safe locks, cabinets, and related security products, while its associated-company industry is wholesale and retail.

CertificationsThe company description explicitly states ISO9001, CE, and RoHS certification or approval, and another slice confirms that products passed CE and RoHS approval. The management-system certification field only says “Others,” so the evidence supports product and quality certifications but does not define additional certifications.

Production capacityThe supplier reports two production lines, six to ten quality-control staff, annual output of 380,000 safe and lock pieces, and a one-month stated lead time. Production-site information is inconsistent: one slice lists 115.0 m², while another claims a 33,000 m² site with a 25,000 m² building area; therefore capacity is evidenced but its scale cannot be fully verified.

Customization capabilityThe supplier explicitly states that its engineering capability enables manufacture of purpose-built products to customer specifications. This directly supports customization capability for metal-forming, joining, and fabrication-related products.
