The IATF 16949: 2016 Certification is required by the main US and European vehicle manufacturers to their suppliers of products intended to be installed on vehicles and allows to have a single international reference, to overcome multiple certifications and to reduce the audits of part two by OEM (Original Equipment Manufacturer) manufacturers.
For OEMs, the IATF 16949 certification is an important selection requirement, so much so that they can check the update status by accessing a worldwide database in which IATF 16949 certified automotive companies are entered.
In Italy, the Accreditation Body is ANFIA (National Association of the Automobile Industry Sector) as the IATF Oversight Office for activities that fall under the IATF 16949 scheme.
