                                              1. How do I verify a supplier¡¯s quality-management certifications?<\/span><\/li>\n<\/ol>\n

                                                Request copies of ISO 9001, IATF 16949 certificates, and recent third-party audit reports. Ask for virtual or onsite factory tours to confirm process controls, calibration labs, and material control plans.<\/span><\/p>\n

                                                                Start with small pilot-run POs with very detailed incoming inspection plans, define upfront warranty and RMA procedures, and scale up order quantities as performance is validated.<\/span><\/p>\n

                                                                  \n
