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.

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.

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.
