CertificationsThe supplier reports ISO 9001 certification and an SGS audit conducted from July 18, 2024 to July 17, 2025. However, the audit evaluation is recorded as “0” without an accompanying interpretation, so the SGS result cannot be treated as a positive qualification.

These statements provide explicit evidence of an established service process.

R&D capabilityThe supplier has no available SDK and reports one R&D engineer. These facts indicate limited documented development resources, while no broader evidence of product innovation or technical development capability is provided.
