AI-Powered supplier vetting

SummaryNingbo Langyao Lighting Technology Co., Ltd. is identified as both a trading company and manufacturer/factory based in Ningbo, Zhejiang, China. It supplies multiple LED lighting products and reports substantial export activity, including self-operated import and export rights and export operations beginning in 2019. The supplier describes structured quality-control activities, including raw-material inspection, in-process testing, final inspection, and verification of certifications. It also states that its products hold CE, RoHS, FCC, UL, and ISO 9001 certifications. The company describes ODM-related product development, including market research, design, prototyping, and production, but independent evidence for broader R&D, OEM, SDK, mold, or 3D-design capabilities is unavailable. It claims 24/7 installation and maintenance support, spare parts, and warranties. SGS audit information is provided, but the meaning of the audit type and evaluation result is not explained. No customer cases are supplied.

Supplier typeThe supplier is explicitly classified as both a trading company and a manufacturer/factory. This indicates a combined manufacturing and trading business model rather than a purely intermediary structure.

CertificationsThe supplier states that its products hold CE, RoHS, FCC, and UL certifications, and that the company holds ISO 9001 certification. These claims provide explicit evidence of certification coverage, although certificate-specific documentation and scope are not included.

After-Sales capabilityLangyao describes 24/7 support for installation and maintenance, replacement parts, warranties, and follow-up surveys. These stated services directly support an established after-sales service capability.

R&D capabilityThe company describes end-to-end ODM development involving market research, design, prototyping, and production, as well as collaboration on specifications and prototypes. However, the available records mark new-product status, ODM status, SDK availability, R&D documentation, private-mold capability, and 3D design services as unknown, so broader innovation strength is only partially evidenced.

Production capacityThe supplier is identified as a manufacturer/factory, offers a broad range of LED products, states that its facilities can handle large orders, and describes raw-material, in-process, and final inspections. These statements provide explicit evidence of production capability, although production capacity figures and independently verified performance data are not provided.

Customization capabilityLangyao states that it consults on customer needs, provides samples and drawings, advises on design and regulatory compliance, and collaborates on specifications, prototypes, and mass production. Its described ODM process further supports the ability to customize products, though the extent of customization options is not quantified.
