AI-Powered supplier vetting

SummaryTOB Technologies Co., Limited is identified as a China-based limited company and trading company, while another record describes the company nature as a factory. Its stated business covers battery products, energy-storage systems, communication equipment, and FTTH solutions. The supplier reports ISO 9001:2015, ISO 14001:2015, and OHSAS 18001 certifications, plus CQC, IEC, and UN38 compliance claims. Production information is inconsistent: one record states a 300 m² manufacturing plant, while the company description claims a 23,000 m² battery-pack line and a fully automatic 18650 cell line with 2 GWh annual output. The supplier lists custom battery packs and multiple battery applications, indicating product customization may be available, but direct customization processes are not documented. Innovation is suggested by R&D, design, and advanced-technology claims, although only one year of total R&D engineer experience is reported. Customer evidence is limited to one recorded transaction and one associated...

CertificationsThe supplier claims ISO 9001:2015, ISO 14001:2015, and OHSAS 18001 certifications, with products described as adhering to CQC, IEC, and UN38 standards. However, the structured certification field records only 'Others', so the available evidence supports certification claims but does not independently verify their scope or validity.

R&D capabilityThe supplier describes itself as a high-tech enterprise integrating research, development, design, production, and sales, and reports advanced battery and energy-storage facilities. However, the structured data reports only one year of total R&D engineer experience, so the scale and depth of innovation resources remain unclear.

Production capacityProduction capability is supported by the factory classification, a stated manufacturing plant, an independent battery-pack production line, a fully automatic 18650 cell line, and a claimed annual output of 2 GWh. The reported facility area is inconsistent across records, with 300 m² in structured data versus 23,000 m² in the company description, so capacity should be verified before reliance.

Customization capabilityThe supplier explicitly lists custom battery packs and custom polymer batteries, alongside battery cells, e-bike batteries, vehicle battery packs, and household energy-storage batteries. This supports the availability of customized battery offerings, although no details on engineering processes, minimum order quantities, or customization limits are provided.
