SummaryGUANGDONG PUSTAR MATERIAL TECHNOLOGY CO., LTD. is identified as a professional technical supplier offering sealant and related chemical, building-material, and technical services. It provides customization, ODM, and OEM services, and reports quality assurance, material traceability, complaint-handling procedures, and corrective-action procedures.

However, it does not provide 3D software design, has no overseas warehouse, showroom, agent, or branch, and has not participated in offline trade shows. No valid manufacturing-capacity contract with its associated subcontractor is reported. The supplier reported no new products in the past year and has no available SDK. Audit information identifies TÜV Rheinland, with a report validity period from February 6, 2026 to February 5, 2027, but the provided result value is not interpretable as a pass or certification conclusion.

Supplier typeThe supplier is explicitly identified as a professional technical supplier. Its stated business scope includes production and sales of non-licensed chemical products, building materials, high-performance sealing materials, and technical services; its primary product is sealant.

After-Sales capabilityThe supplier has in-stock service capability and documented procedures and records for handling customer complaints, corrective and preventive actions, and quality assurance. However, it has no overseas warehouse, showroom, agent, or branch, limiting the evidenced overseas service infrastructure.

R&D capabilityThe supplier provides ODM services and has R&D capability for customization, but it reported no new products during the past year and has no available SDK. These explicit limitations prevent a positive assessment of product innovation capability.

Production capacityThe supplier reports in-stock capability, lead times within 15 working days in both peak and off-seasons, and a business scope covering chemical products, building materials, sealants, and technical services. Nevertheless, it has no valid contract with its associated subcontractor for manufacturing capacity, creating a stated production-governance deficiency.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides ODM services, demonstrating broad evidenced customization capability.

Client casesThe supplier explicitly reports OEM service for well-known brands, which provides evidence of branded-customer experience. No customer names, project details, product volumes, or independently verifiable case documentation are provided.
