AI-Powered supplier vetting

SummaryXuzhou Sun Hong International Trade Co., Ltd. is identified as a China-based limited company in Jiangsu, described both as a manufacturer/factory and a trading company. It reports extensive customization and ODM capabilities, OEM service for well-known brands, 50 quality-control staff, and production lines for pulp and paper and oil-air-fuel filters. The supplier has 14 years of export experience, self-operated import/export rights, and exports to multiple global regions. Service coverage is limited by the absence of overseas agents, branches, warehouses, showrooms, and offline trade-show participation. R&D evidence is mixed: 3D design and professional technical support are available, but no new products were reported in the past year, no patents or private molds are stated, and no SDK is available. Certification holding and financial credibility cannot be confirmed from the provided information.

Supplier typeThe supplier is described as a limited company located in Xuzhou, Jiangsu, China, with company information identifying it as both a manufacturer/factory and a trading company. This indicates mixed manufacturing and trading positioning rather than a clearly exclusive factory profile.

After-Sales capabilityThe supplier reports in-stock service capacity and documented procedures with records for corrective actions and customer complaints. However, it has no overseas warehouse, showroom, overseas agent or branch, and serves zero stated overseas countries, which limits evidence of localized after-sales coverage.

Production capacityThe supplier reports in-stock capability, 50 quality-control staff, defined production lines for pulp and paper and oil-air-fuel filters, and a one-month off-peak lead time. Outsourcing procedures and manufacturing-capacity contracts are unknown, so production governance is only partly documented.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization, supported by ODM and 3D software design services. This is direct evidence of broad customization capability, although no private-mold capability is stated.

Client casesThe supplier states that it provides OEM services for well-known brands, which is evidence of brand-related customer experience. No customer names, project details, or independently verifiable case descriptions are provided, so the depth of these cases cannot be assessed.
