SISA has always maintained high-quality service through strict supply chain management and quality control procedures. We promise to meet the quality requirements of all customers and strive to be perfect. We have been managing every link of "purchase quality inspection delivery" in strict accordance with the workflow of ISO 9001:2008 certification.

To ensure we receive only authentic, quality parts and to protect against counterfeit components, potential suppliers are subjected to a rigorous screening process. In addition, our goods are subjected to a stringent testing process based on the highest standards and norms. This process takes place both in our incoming and outgoing goods departments, allowing us to ensure that only original, defect-free manufacturer goods leave our warehouse.
