AI-Powered supplier vetting
SummaryLangir demonstrates established manufacturing, OEM/ODM, customization, quality-control, and customer-support capabilities. It operates five production lines, reports switch production of 600,000 pieces, and exports to multiple global regions, with 90% of total sales from exports. The supplier states that its products meet IP67/IP68, UL, CE, and RoHS standards. It has procedures for corrective and preventive actions and customer complaints, and finished-product inspection instructions are uniformly followed. However, it reports no in-stock service capacity, overseas warehouse, showroom, overseas agent or branch, or available SDK. Innovation evidence is mixed: ODM is available, but no new products were reported in the past year and total R&D engineer experience is six years. Financial information is limited to the availability of records for 2022–2024, without performance details.
Supplier typeThe supplier presents itself as a manufacturer providing product selection guidance, prototyping, OEM/ODM services, customization, and after-sales support. Its stated production infrastructure includes five production lines, stamping and laser-marking facilities, and self-operated import/export rights, indicating a manufacturing-oriented supplier rather than a pure trading company.
CertificationsLangir states that its products meet IP67/IP68, UL, CE, and RoHS standards, covering ingress protection, safety, and environmental compliance. The provided information identifies claimed compliance standards but does not include certificate numbers, issuing bodies, or validity dates.
After-Sales capabilityThe supplier describes after-sales support and troubleshooting and has clear procedures and followed records for corrective and preventive actions and customer complaints. However, it has no in-stock service capacity, overseas warehouse, showroom, overseas agent, or branch, which limits local and rapid overseas support.
Production capacityThe supplier operates five production lines, reports switch production of 600,000 pieces, and has stamping and laser-marking facilities. It has a valid manufacturing-capacity contract with associated subcontractors, an outsourcing SOP, and uniformly followed finished-product inspection instructions, but it does not perform ongoing quantity reconciliation for every batch or production run.
Customization capabilityThe supplier explicitly offers prototyping, OEM/ODM services, custom solutions tailored to operational needs, and customization from samples. It also reports OEM service for well-known brands, providing direct evidence of both product customization and contract-manufacturing capability.
