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.
