Several important capabilities—including outsourcing procedures, inventory services, overseas facilities, R&D services, OEM/ODM, traceability, and customer cases—are marked unknown. An SGS audit record is available for the period from May 17, 2025 to May 16, 2026, but the stated evaluation result is not interpretable from the provided value alone.
