Raw Material Inspection System 1 Purpose: To conduct specified inspections on raw materials, semi-finished products, and finished products in order to ensure that the products meet the required standards. 2 Scope Applicable to the control of incoming materials, in-process, and final inspections. 3 Responsibilities and Authorities: The factory is responsible for incoming material inspection, in-process inspections, final product inspection, as well as conducting self-inspections at each stage of production. The Technical Department is responsible for preparing the documents used for inspection ； 4 Program Overview 4.1 The Technical Department formulated the \"Raw Material Inspection System\" (document number GZ-B/1-2005), which specifies the documents that serve as a basis for inspecting raw materials as well as the quality records to be maintained. 4.2 Incoming material inspection and testing a) Raw materials and auxiliary materials must pass inspection or verification before they can be put into use or processed. When determining the methods for incoming material inspection or verification, the control procedures for the suppliers that provide the raw materials should be taken into account, and these procedures should be specified in writing. b) If verification is not possible due to urgent production needs, or if a full verification in accordance with regulations cannot be carried out, emergency release may be permitted only with the approval of an authorized person, along with appropriate labeling and documentation. The relevant documents should specify the scope permitted for emergency release. c) Inspectors shall strictly inspect or verify the purchased materials in accordance with the \"Raw Material Procurement Inspection System\" to ensure that materials that have not been inspected or verified are not allowed to enter the warehouse or be put into use. 4.3 Process inspection and testing a) The operators responsible for each process are tasked with conducting self-inspections of those processes; only after a successful self-inspection can a specialized inspection be carried out. Self-inspections are not considered part of the company’s formal inspection procedures. b) The items and methods for in-process inspection and testing shall be determined, specified in writing, and strictly implemented to ensure that only semi-finished products that have passed the inspection may be stored or moved to the next stage of production. c) Materials shall not be released until the required process inspection or verification is completed; the company does not permit the exception-based release of semi-finished products. 4.4 Final inspection and testing a) The final inspection must be carried out only after the specified incoming material inspections and in-process inspections have been completed. b) The items and methods for final inspection and testing shall be documented, and the inspectors shall carry out all final inspections and tests strictly in accordance with the specified documents to ensure that the products meet the required standards. c) The product can be released only after all the relevant data and documents for the specified inspection and testing activities are available and approved by the company’s authorized personnel. 4.5 Non-conforming products identified during inspection and testing activities shall be handled in accordance with the requirements of 4.3. 4.6 Inspection and test records a) The authorized inspector shall record the results of inspections or verifications accurately; the records shall clearly indicate whether the product has passed the inspections or verifications in accordance with all specified acceptance criteria, and shall also specify the authorized inspector responsible for releasing the product. b) The authorized inspector shall keep the quality records of the inspections and tests specified in clauses 4.2 to 4.4. 5 Relevant record documents: «Records of First Articles and Interim Sampling Inspections», «Product Quality Inspection Records», «Verification Records for Products Purchased/Outsourced/Provided by Customers»
