AI-Powered supplier vetting

SummaryBeijing Tester Integrated Housing Co., Ltd. is a China-based limited company established on 2025-07-23, with 240 employees and seven production lines. It offers various modular and container-house products and provides 3D software design, ODM, and multiple customization options. However, the supplier is not identified as a professional technical supplier, reported no new products in the past year, and has no SDK availability. Manufacturing controls show gaps: there is no valid manufacturing contract with affiliated subcontractors, no outsourcing SOP, and no ongoing production quantity reconciliation. The supplier has no stock, overseas warehouse, showroom, overseas agent or branch, or offline trade-show participation. Financial credibility cannot be established because the provided financial figures are zero and the company is newly established; no monetary figures are reproduced here. No certification holdings, after-sales service capability, or customer cases are documented.

Supplier typeThe supplier is a China-based limited company with a combined business type, established on 2025-07-23. Its offered products include container houses, expandable houses, folding houses, detachable and flat-pack container houses, apple cabins, and capsule houses, while its stated business scope also includes packaging, freight forwarding, automotive spare parts, and sanitary ceramic products.

R&D capabilityThe supplier provides 3D software design services and ODM services, but it is not identified as a professional technical supplier, reported no new products in the past year, and has no available SDK. The evidence supports some design-related capability but not strong demonstrated product innovation.

Production capacityThe supplier reports seven production lines, seven experienced export-trade staff, and average peak- and off-season lead times within 15 workdays. However, it has no valid manufacturing contract with affiliated subcontractors, no outsourcing SOP, and no ongoing quantity reconciliation for each batch or mass production, creating documented production-control deficiencies.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, and also provides ODM services and 3D software design services. These statements provide direct evidence of broad customization capability.
