Supplier typeThe supplier is identified as Zhongshan Kaiying Hardware Manufacture Co., Ltd., a combined business entity and limited company located in Zhongshan, Guangdong, China. It was established on 2013-07-15 and has 147 employees, providing clear legal, geographic, and organizational identification.

CertificationsThe supplier holds an ISO9001:2015 management-system certificate. Product compliance certification is listed only as “Others,” so the evidence supports a management certification but does not identify specific product-standard certifications.

After-Sales capabilityThe supplier has written procedures and followed records for customer complaints, corrective and preventive actions, and service-capability assessment. It also has inventory capability and accepts multiple service payment and quotation terms, but lacks overseas warehouse and showroom capabilities.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, employs five R&D engineers, and has one national science and technology progress award. However, it has no available SDK and no internationally recognized design awards; overall, the evidence still demonstrates active innovation capability.

Production capacityProduction resources include CNC, punching, blister sealing, high-frequency plastics welding, hole-punching, and key-engraving/milling machines. The supplier reports inventory capability, 200 qualified suppliers, documented finished-product inspection, and exports equal to 90% of total sales, although it has no valid contract with affiliated subcontractors.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These services are stated in both its R&D and design-capability information, directly supporting broad customization capacity.

Client casesThe supplier states that it has not collaborated with Fortune 500 companies and does not provide OEM services for popular brands. Although repeat buyers are reported at 80%–100%, no named customer cases or verifiable major-brand references are provided.
