AI-Powered supplier vetting

SummaryShandong Longantai Environmental Technology Co., Ltd. presents evidence of professional technical-supplier status, private mold development, 3D design, full customization, ODM and OEM services, and a recent new-product record. Its service-management procedures cover supplier assessment, corrective actions, and customer complaints, while finished-product inspection instructions are documented and followed. The supplier holds ISO9001:2015, ISO14001, and ISO45001:2018 certifications and reports regular fire drills. Production evidence includes three production lines, but the factory does not continuously reconcile quantities for each batch or production run. International-service infrastructure is limited: it reports no overseas warehouse, showroom, agent, branch, or offline trade-show participation. Financial records are identified for 2021–2023, but no substantive financial performance details are provided. Customer-related evidence includes OEM service for well-known brands, although no customer names or...

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and is described as providing industrial wastewater treatment solutions. This indicates a specialized environmental-technology supplier rather than a general trading company.

CertificationsThe supplier reports holding ISO9001:2015, ISO14001, and ISO45001:2018 certifications. These stated certifications provide explicit evidence of quality, environmental, and occupational health and safety management systems.

After-Sales capabilityThe supplier has written and followed procedures for service-capability assessment, corrective and preventive actions, and customer complaints. However, it reports no overseas warehouse, showroom, agent, branch, or overseas-service coverage, limiting evidence of localized international after-sales support.

R&D capabilityEvidence includes private mold development, 3D software design, a new product within the past year, ODM services, OEM service for well-known brands, and one national science and technology progress award. The supplier lacks an available SDK, but the broader evidence supports active product and technical development.

Production capacityThe supplier reports three production lines and facilities including cutting, veneer reeling, submerged arc welding, and painting equipment, with one-month average lead times in both peak and off-season periods. Finished-product inspection instructions are uniformly followed, but the factory does not continuously reconcile quantities for every batch or production run.

Customization capabilityThe supplier explicitly offers customization from designs and full customization, supported by private mold development and 3D software design services. This provides direct evidence of both design-based and comprehensive customization capability.
