AI-Powered supplier vetting

SummaryGUANGZHOU RT AIR FILTECH CO., LTD. is identified as a combined company offering manufacturing, export, service, quality control, and R&D capabilities. The supplier reports broad customization, ODM and new-product development capability, OEM service for recognized brands, documented complaint and corrective-action procedures, and quality assurance processes. Production-related evidence includes multiple facilities and equipment, with peak- and off-season lead times stated as within 15 workdays. However, the supplier reports no in-stock capacity, overseas warehouse, overseas showroom, overseas agents or branches, or offline trade-show participation. No certification information is provided, and customer-case evidence is limited to one associated buyer name and a claimed OEM relationship without further details.

Supplier typeThe supplier is identified as GUANGZHOU RT AIR FILTECH CO., LTD. and classified as a combined company. Its listed offerings cover general information, export trade, manufacturing, service, quality control, R&D, and photos, indicating an integrated supplier profile rather than a service-only entity.

After-Sales capabilityThe supplier reports clear procedures and followed records for corrective and preventive actions and customer complaints, along with written supplier-service assessment procedures. However, it also reports no in-stock service capacity, overseas warehouse, overseas showroom, overseas agents or branches, and no countries with overseas services, limiting evidence of local or rapid after-sales support.

R&D capabilityThe supplier reports new products during the past year, ODM service, and customization from samples, designs, full and flexible customization. It does not have an available SDK, but the stated product-development and ODM evidence supports innovation capability for physical filtration products.

Production capacityThe supplier has valid manufacturing contracts with each related subcontractor, lists multiple production facilities and machines, and states average lead times within 15 workdays in both peak and off seasons. It reports no inventory capacity, so production responsiveness is supported but stock-based fulfillment is not.

Customization capabilityBoth R&D and design-service entries explicitly list customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization capability.
