AI-Powered supplier vetting
SummaryEB China is an industrial equipment and materials supplier involved in petroleum drilling and production equipment, metallurgical equipment, special steel, non-ferrous alloys, new-material technology, and installation services. Its stated manufacturing scope includes castings, forgings, machinery, and e-bike products, with substantial annual capacity figures. The supplier reports ISO9001, ISO14001, and ISO45001 certifications for its factories. It has documented procedures for corrective and preventive actions, complaint handling, supplier-service assessment, and approved-supplier updates. However, quality traceability, quality-assurance status, and testing-equipment quantity are either unknown or reported as zero. R&D resources are limited to one engineer, with no new products reported in the previous year and no available SDK, although ODM, OEM, sample-based, and design-based customization are offered. Overseas service infrastructure and offline trade-show participation are absent. Customer-facing...
Supplier typeThe supplier operates across industrial equipment, specialized metals, foundry, forging, machinery, and e-bike manufacturing activities. Its stated scope also includes new-material R&D and installation services, indicating a manufacturer and industrial solution provider rather than a purely trading company.
CertificationsThe company states that its e-bike assembly factory, foundry and forging plant, and machinery plant have passed ISO9001, ISO14001, and ISO45001 management-system certification. The slices do not provide certificate numbers, validity dates, or issuing-body details.
After-Sales capabilityThe supplier has documented corrective/preventive-action and customer-complaint procedures with followed records, plus written procedures and records for assessing service capability. However, it has no overseas showroom, overseas agent or branch, or offline trade-show participation, so international service coverage is limited despite formal process evidence.
R&D capabilityInnovation resources appear limited: the supplier reports one R&D engineer, no new products in the previous year, and no available SDK. It does provide ODM and OEM services and undertakes customization, but the evidence does not demonstrate strong ongoing product innovation.
Production capacityThe supplier reports annual output capacities of 100,000 tons for castings, 30,000 tons for forgings, and up to 1,000,000 sets for machinery and E-V products, supported by 21–30 quality-control staff. However, the stated quantity and size of quality-control test equipment is zero, creating a clear production-quality control deficiency.
Customization capabilityThe supplier explicitly offers customization from samples, graphic or design inputs, and general customization, alongside ODM and OEM services for popular brands. These statements directly support capability for both customer-specified and original-design manufacturing.
