Stellantis Requires All Parts Suppliers to Establish Full-Chain Supply Correspondence

In early November 2026, Stellantis sent a notice to all component partners requiring them to establish full-chain supply correspondence relationships from Tier 1 suppliers to Tier 2, Tier 3 and even more upstream tiers. The data collection will prioritize semiconductor categories and Tier 1 partners with larger business volumes, with all collected information uploaded to a designated third-party platform. Stellantis has signed service agreements with supply chain risk management companies Resilinc and Altana. Under Stellantis' published global procurement terms, the group has the authority to audit and verify suppliers' operational records, core data, production sites and full-process operating standards. Stellantis Chief Purchasing Officer Monica Genovese stated that achieving supply chain visibility across Tier-N levels has become a requirement for the global automotive industry. Michigan lawyer Dan Sharkey noted that suppliers' core confidential business information faces leakage risks, and upstream supply data could be used by automakers as leverage to drive down procurement prices. In October 2025, General Motors sent survey questionnaires to partners to confirm whether they had purchased chips from Nexperia, the Dutch chip company under Wingtech Technology, and the specific procurement scale. Nexperia focuses on producing basic discrete devices, which are mostly directly soldered into components such as electronic control units and purchased directly by Tier 1 suppliers. The European Automobile Manufacturers' Association issued a warning at the time that its member companies could face full production stoppages within days. After the 2011 Great East Japan Earthquake, Toyota spent three weeks investigating the damage to its supply chain, halting production for two weeks and reducing output for six months afterward. In 2013, Toyota jointly developed the RESCUE system with Tier 1 suppliers, which registered 400,000 suppliers. When a strong earthquake struck Niigata Prefecture in 2019, Toyota confirmed within half a day that its supply system had not been affected. In 2022, General Motors partnered with suppliers to launch a digital supply chain management tool that aggregates data from thousands of suppliers and monitors operational status at production sites worldwide. During the 2024 hurricanes that hit the southeastern United States, the tool helped GM anticipate which supplier factories might be affected. Germany launched the Catena-X automotive data sharing project in 2021, under which data ownership belongs to the data provider, who decides the scope and conditions of sharing. Multiple automakers have joined. Stellantis previously reached a cooperation agreement with Leapmotor, and data traceability for subsequently co-produced models will extend to Chinese suppliers within the Leapmotor system. China has introduced compliance regulations for the cross-border transfer of important automotive-related data. The cross-border automotive data ecosystem built by China and Germany under the Catena-X framework will begin operations in mid-November 2026, initially serving EU battery passport regulatory requirements.
