After-Sales capabilityThe supplier reports clear, followed procedures for customer complaints and corrective/preventive actions, plus inventory capability and standard quotation/payment options. However, it has no overseas warehouse, showroom, overseas agents or branches, and offers overseas service coverage in zero countries, indicating documented service processes but limited overseas infrastructure.

R&D capabilityThe supplier states that it had new products during the past year and provides ODM services, supporting active product-development capability.
