AI-Powered supplier vetting

SummaryBeijing Rubble Technology Co., Ltd. is a China-based limited company identified as both a trading company and manufacturer/factory, with a valid import/export license. It reports ISO 9000 and ISO 9001 certification, five production lines, quality assurance, and complaint-handling procedures. The supplier offers broad customization, ODM services, and had new products during the past year, indicating established R&D and product-development capability. It also reports OEM service for well-known brands and in-stock capacity. However, its overseas service infrastructure is limited: it has no overseas warehouse, showroom, agent, or branch, serves zero stated overseas countries, and has not participated in offline trade shows. Service-capability assessment and corrective-action systems lack written procedures or records. Customer cases are not explicitly documented, so this field cannot be confirmed.

Supplier typeThe supplier is described as both a trading company and manufacturer/factory, specifically Beijing Rubble Technology Co., Ltd., a China-based limited company with six employees and a valid import/export license. This indicates an officially identified entity with both trading and manufacturing classifications, although the limited employee count suggests a relatively small organization.

CertificationsThe supplier reports certification to ISO 9000 and ISO 9001. These are explicit quality-management certifications and support a positive assessment of its certification holding.

R&D capabilityThe supplier reports new products during the past year, ODM services, six-to-ten years of R&D engineer experience, and OEM service for well-known brands. It supports multiple customization modes, although no SDK is available, so the evidence supports meaningful product-development capability with a specific limitation in SDK support.

Production capacityThe supplier reports five production lines, in-stock capacity, and an average lead time of within 15 working days to one month depending on the stated season. It also lists fewer than five quality-control staff and 12 qualified service-capability suppliers, providing some operational evidence, although the available information does not quantify production output.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides ODM services, directly supporting a broad customization capability.
