AI-Powered supplier vetting

SummaryFoshan Sharmeal Technology Co., Ltd. is a China-based trading company established in December 2022, operating with 10 employees as a limited company and no reported group affiliation. It holds a valid import and export license, reports export sales of 51%–70%, and accepts FOB, CIF, CFR, and EXW quotation terms. The supplier demonstrates broad customization capability, ODM services, recent new-product activity, and OEM service for well-known brands. It also reports inventory capacity and documented procedures for corrective actions and customer complaints. However, it has no overseas warehouse, showroom, agent, or branch, and no available SDK. Raw-material traceability and quality-assurance status are unknown. The available information does not establish direct production capacity, certifications, financial strength, or verified customer cases.

After-Sales capabilityThe supplier has clear procedures and followed records for handling customer complaints and corrective/preventive actions. It also offers several international quotation terms, but has no overseas warehouse, showroom, agent, or branch, which limits evidence of local after-sales infrastructure.

R&D capabilityThe supplier reports R&D capability, new products during the past year, and ODM services. It also states that no SDK is available, so the evidence supports product-development activity but not SDK-based technical integration.

Customization capabilityThe supplier explicitly lists customization from samples, designs, full customization, minor customization, and flexible customization in both its R&D and design-service information. It also reports ODM service, providing strong evidence of broad customization support.

Client casesThe supplier states that it provides OEM services for well-known brands, which is evidence of brand-related customer experience. However, no customer names, project details, order history, or independently verifiable case information are supplied.
