Mahindra, Tata shift to just-in-case

Indian automakers are rebuilding supply chains around a simple assumption: disruptions will keep coming. Economic Times reported on May 22 that carmakers including Mahindra & Mahindra and Tata Motors are moving from just-in-time inventory toward larger “just-in-case” buffers, with critical component stocks rising to three to six months from roughly 30-45 days. That change follows a run of shocks that no longer look temporary. Economic Times said the triggers include geopolitical tensions affecting shipping routes, semiconductor constraints linked to the AI boom and tighter policies around critical minerals. Mahindra has increased inventory buffers, diversified suppliers and is monitoring potential disruptions in real time, while Tata Motors told the paper it is focusing on localisation, supplier diversification and “selective buffers” for critical components.

Economic Times said inventories of critical auto components that were once held for 30-45 days are now being held for three to six months. The shift applies especially to parts with imported content or higher disruption risk, according to suppliers cited by the paper. (economictimes.indiatimes.com) Prasanth Doreswamy, president and chief executive of AUMOVIO India, told Economic Times that customers are demanding larger reserves for critical parts because “one disruption inevitably triggers many more.” Ashim Sharma, senior partner at Nomura Research Institute, told the newspaper that the cost of production outages can far exceed the added cost of holding inventory.

In its 2023-24 integrated annual report, the company said supply-chain disruption can affect the business and that it audits identified suppliers for environmental, safety, labor and financial risks, with mitigation plans submitted after those reviews. (economictimes.indiatimes.com) Mahindra’s 2024-25 annual report also points to a more digital operating model. The company said its manufacturing systems use digital twin tools, smart sequencing and remote shop-floor viewing to enable faster risk assessment and real-time monitoring. Tata Motors has framed the response in similar terms. Economic Times reported that Tata is emphasizing localisation and supplier diversification while keeping selective buffers for critical components. (mahindra.com) Tata’s sustainability reporting also shows the scale of its domestic manufacturing footprint, with seven plants in India on a standalone commercial-vehicle basis.

Economic Times said the impact extends to smaller suppliers, particularly where imported content raises exposure to shipping or policy disruptions. (economictimes.indiatimes.com) Localisation becomes more than a cost target in that setup. If an automaker wants backup capacity, shorter lead times and fewer single-source dependencies, suppliers with domestic sourcing options, multiple approved vendors and better planning visibility have an advantage, according to the companies’ stated strategies and the executives cited by Economic Times. That is an inference from the measures they described. (economictimes.indiatimes.com) ### Is this only about inventory, or also about control systems? The inventory build is only one part of the response. Mahindra’s supplier-risk audits and digital monitoring tools, along with Tata’s emphasis on diversification and localisation, show that automakers are also trying to identify disruption earlier and reduce dependence on any one source. The next public markers will come through company filings and earnings commentary. (economictimes.indiatimes.com) Mahindra’s annual-report disclosures and Tata Motors’ investor materials are the places to watch for updated language on buffers, localisation and supplier-risk controls in fiscal 2026.
