AI-Powered supplier vetting

SummaryHangzhou DAYTAI Network Technologies Co., Ltd. is identified as a China-based limited company in Hangzhou, Zhejiang, with company records also describing it as a trade company and as a manufacturer/factory. Its stated product range centers on fiber-optic and related telecommunications products. The supplier reports more than 10 production lines, 41–50 quality-control staff, annual fiber-optics productivity of 200,000 tons, broad export-market coverage, self-operated import/export rights, and exporting activity since 2002. ISO 9001, ISO 20000, and QC 080000 certifications are listed, and total R&D engineer experience is stated as 21–30 years. However, overseas service capabilities, product development, OEM/ODM, 3D design, SDK, sustainability systems, raw-material traceability, new-product launches, and customer case details are largely unknown. An SGS audit is recorded with a stated evaluation result of 0, but the provided slices do not explain the scoring criteria.

Supplier typeThe records identify the supplier as a trade company in Hangzhou’s information transmission, software, and IT services industry, while another record classifies it as a manufacturer/factory. It is a China-based limited company, so the available information supports both trading and manufacturing roles but contains a classification inconsistency.

CertificationsThe supplier lists ISO 9001, ISO 20000, and QC 080000 management-system certifications. These are explicit certification claims, although no certificate validity dates or issuing-body details are provided.

After-Sales capabilityThe company description states that a professional customer service team is available to consult customers on product-related issues. However, overseas warehouses, showrooms, agents or branches, and offline trade-show participation are all marked unknown, so the breadth of after-sales and local support cannot be established.

Production capacityThe supplier reports more than 10 production lines, 41–50 quality-control staff, and annual fiber-optics productivity of 200,000 tons. It also states broad export coverage and self-operated import/export rights, providing explicit evidence of substantial production and export capability.
