AI-Powered supplier vetting

SummaryThe supplier is a China-based limited company established in 2016, with reported export activity, a valid import/export license, and primary products covering speakers, audio equipment, amplifiers, microphones, mixers, and Dante audio. Evidence indicates established service procedures, corrective and preventive action records, technical support, R&D documentation, 3D design services, customization capabilities, and recent new-product development. Production information includes four production lines, six to ten quality-control staff, stated lead times of within 15 workdays in off-peak periods and one month during peak periods, and export markets across Southeast Asia, the Middle East, Europe, and North America. FCC and RoHS certifications are reported, but the supplier lacks a factory environmental impact assessment report. No financial figures are included in this assessment. Customer-specific cases are not provided.

Supplier typeThe supplier is identified as a combined business entity and limited company, operating in Guangdong, China. It is reported as independent of a larger company group and has a valid import/export license, indicating a formally registered standalone trading and manufacturing entity based on the supplied information.

CertificationsThe supplier reports FCC and RoHS product certification capability, and an audit record conducted by BV is listed with a validity period from January 7, 2026 to January 6, 2027. However, the supplier explicitly lacks a factory environmental impact assessment report, so the certification evidence is positive but not comprehensive across environmental documentation.

After-Sales capabilityService capability is supported by written procedures, followed records, an approved supplier list, and a corrective and preventive action mechanism. Technology engineers are also responsible for technical support during production and after-sales service, providing explicit evidence of organized technical and after-sales support.

R&D capabilityThe supplier has R&D engineers responsible for new product development and maintains design input, output, review, verification, and validation documentation for audit. It also reports new products during the past year and provides 3D software design services, supporting a demonstrated innovation function.

Production capacityThe supplier reports four production lines, six to ten quality-control staff, 29 or 56 total employees in different slices, and stated order fulfillment times of within 15 workdays off-peak and one month during peak season. The differing employee counts create a data inconsistency, but the production-line, quality-control, and lead-time information provides explicit evidence of operating production capacity.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its engineers confirm customer requirements and provide technical production support, while 3D software design services further support customized product development.
