SummaryGuangdong Longying Industrial Technology Co., Ltd. is a China-based trading company established in 2018 with 13 employees and an address in Guangzhou, Guangdong. It offers solar street lights and operates across several new-energy and lighting-related business areas. The supplier demonstrates professional technical R&D status, 3D software design, flexible customization, and ODM services. However, it reported no new products in the past year and has no available SDK. Quality and service-control documentation is weak: no written quality assurance, complaint-handling, corrective-action, or service-assessment procedures were identified. Overseas service presence is limited, with no overseas showroom, agents, branches, or recorded offline trade-show participation. Financial evidence is limited to year labels rather than substantive financial metrics. An audit by TUV Rheinland is recorded, but the audit type and evaluation result are coded numerically without explanatory certification details.

Supplier typeThe supplier is explicitly identified as a trading company and limited company based in Guangdong, China, with 13 employees. Its listed business scope includes lighting fixtures, semiconductor lighting devices, wind turbines, generators, and new-energy vehicle battery-swapping facilities; its primary offered product is solar street light.

After-Sales capabilityThe supplier has no written procedures or records for corrective and preventive actions, customer complaint handling, or effective service-capability assessment. It also has no overseas showroom, agents, branches, or recorded overseas-service countries, although it states acceptable quotation and payment terms and gives lead times of one month in peak season and within 15 workdays in the off-season.

R&D capabilityThe supplier identifies itself as a professional technical supplier, provides 3D software design and ODM services, and describes technology R&D and innovation as part of its business positioning. However, it reported no new products during the past year and has no available SDK, indicating that current innovation evidence is limited.
