AI-Powered supplier vetting

SummaryNingbo Kelina Electric Appliance Co., Ltd. is a China-based limited company established in 2017, operating from Zhejiang with 85 employees and a 4,500 m² manufacturing plant. It offers vacuum cleaners and several garden, agricultural, automotive, and household products. Evidence indicates nine production lines, stated vacuum-cleaner output of 700,000 pieces, six to ten quality-control staff, ISO 9001:2015 certification, OEM capability, and some export experience across North America, East Asia, Southeast Asia, and the Middle East. The supplier reports product development activity and dedicated design and quality departments, but after-sales service, financial credibility, and detailed customer references are not sufficiently documented. Its profile also contains mixed classifications as both a trade company and a company with manufacturing operations, so the exact business model should be verified.

CertificationsThe supplier explicitly reports holding an ISO 9001:2015 management-system certificate. The provided information does not specify the certificate scope, issuing body, validity period, or product-specific certifications.

R&D capabilityThe supplier states that it has a design department, actively follows market trends, develops new models every year, and has two R&D engineers’ total experience recorded. These statements support an established product-development function, although the scale and outcomes of innovation are not independently detailed.

Production capacityThe supplier reports a 4,500 m² plant, nine production lines, six lines for home appliances and three for garden tools, six to ten quality-control staff, and annual vacuum-cleaner output of 700,000 pieces. It also states one-month off-peak lead time and two-to-three-month peak-season fulfillment, providing explicit evidence of operational production capacity.

Customization capabilityThe supplier explicitly offers OEM production, reports providing OEM services for some well-known domestic brands, and states that exclusive sales arrangements can be offered to major customers. This supports customization and private-label capability, although the available information does not describe tooling, minimum order quantities, or customization scope.

Client casesThe supplier cites sales of more than one million units for model LF-11, OEM supply to well-known domestic brands, introduction of a portable water pump on CCTV Agriculture Channel, domestic e-commerce activity, and exports to several countries. These are stated market and product examples, but named customers, verifiable case studies, and performance documentation are not provided.
