The company's responsibility for the products produced has started since the raw materials have just arrived and have not been received by the company's raw material storage/warehouse personnel by carrying out inspections of the raw materials they will receive. After the results of the inspection ensure that the raw materials to be received are in accordance with the specified requirements, then the raw materials are received and stored in the raw material storage warehouse.

During the production process, the quality control team periodically conducts laboratory tests to ensure that the products produced have been made according to the provisions and have the required quality.
