AI-Powered supplier vetting

SummaryWeifang Beidi Plastic Industry Co., Ltd. is identified as a professional PVC-U profile supplier with stated annual production capacity of 120,000 tons and more than 1,000 employees. It reports ISO9001, SGS, and CE certifications, provides 3D design, ODM, OEM, and multiple customization options, and launched new products during the past year. Its service capability includes a complaint-handling procedure with records, overseas agents or branches, and participation in the 137th Canton Fair. However, quality assurance and traceability statuses are unknown, quality-control test equipment is reported as zero in one slice, no overseas warehouse or showroom is available, and no SDK is offered. Financial credibility cannot be assessed from the non-financially reported year references.

Supplier typeThe supplier is explicitly described as a professional technical supplier specializing in PVC-U profile research, development, production, and sales. Its stated scale includes more than 1,000 employees and annual production capacity of 120,000 tons.

CertificationsThe company description explicitly states that the supplier has passed ISO9001 quality management system certification, SGS certification, and CE security certification.

After-Sales capabilityTechnology engineers provide technical support for after-sales service, and the supplier has a clear customer-complaint procedure with followed records. It also reports overseas agents or branches, although it has no overseas warehouse or showroom and its overseas-service country count is stated as zero.

R&D capabilityThe supplier reports professional R&D capability, two R&D engineers, new product development during the past year, and ODM capability. Its engineers are responsible for customer-request confirmation, technical after-sales support, and new product development; however, no SDK is available.

Production capacityThe supplier reports annual UPVC profile productivity of 120,000 tons, more than 1,000 employees, and production lines, testing equipment, and processing technology described as cutting edge. However, one quality-control slice records the quantity and size of quality-control test equipment as zero, creating a limitation in the available production-quality evidence.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, together with 3D software design services and ODM capability.

Client casesThe supplier states that its products are sold in Europe, Africa, North America, and Central Asia, and reports OEM service for popular brands. These statements indicate market and brand-serving experience, but no specific customer names or documented case details are provided.
