As Apple promotes diversification of its supply chain and reduces its dependence on China, India has become an important base for iPhone production. Currently, about a quarter of the world's iPhones are produced in India. The Tata Group plays a key role in this layout and is responsible for the production of iPhone back casings and other components.
However, the Tata Electronics iPhone parts factory in Hosur, Tamil Nadu, India, once faced the risk of being ordered to suspend production. Now the local environmental protection regulator has officially withdrawn the relevant actions, and the factory is no longer in danger of being shut down.
The controversy originated in 2025 when local farmers complained to the government that wastewater discharged from Tata factories polluted surrounding farmland and open wells, affecting agricultural production and groundwater quality. From December 2025 to May 2026, the Tamil Nadu Pollution Control Board (TNPCB) conducted five on-site inspections and threatened to close the factory that supplies components to Apple based on the test results. Regulators initially believed that the factory's rainwater collection tank overflowed due to wastewater discharged from the factory, causing groundwater contamination in adjacent farmland.
The turning point occurred in mid-June 2026. Tata said in a statement to Reuters that the company had responded to all pollution concerns raised by regulatory authorities and that the relevant rectification and explanation work had been recognized by the TNPCB. Tata noted that the company "has responded satisfactorily to all issues raised by the regulator" and therefore the regulator "will not take any further action on this matter." According to Tata, the latest water sample report collected and tested by the TNPCB shows that the water quality from the Hosur factory and its rainwater recycling facilities shows no signs of pollution, and all indicators are within the limits of regulations.
Prior to this, Tata was allegedly informed of the potential contamination problem on December 23, 2025, but failed to respond. In order to self-certify compliance, the company previously commissioned independent water sample analysis, and the results showed that both discharge and water quality met relevant environmental standards. Now, Tata claims that the latest test results from regulators are consistent with this independent analysis and found no contamination from its factories. However, although the regulatory authorities finally withdrew the threat of closure, the outside world is still unable to fully clarify whether the farmland water bodies in Tamil Nadu have ever been truly contaminated, and why the conclusions drawn by the TNPCB in five consecutive early tests are significantly different from the latest results.
At present, neither the TNPCB nor Apple has publicly commented on this "contrast". From an outside perspective, either the regulatory authorities have made multiple misjudgments in previous tests, or they have changed their stance due to some external pressure. This also adds uncertainty and room for public opinion discussion to the incident.
In Apple's global supply chain system, Tata, Foxconn, Pegatron and other companies jointly form the local iPhone production network in India. Foxconn is mainly responsible for the assembly of the whole machine, while Tata plays an important role in the parts manufacturing process. In 2024, Tata reached an approximately US$1 billion cooperation agreement with another key supplier, Pegatron, to expand its iPhone manufacturing capabilities in Tamil Nadu. Earlier, Tata also acquired Wistron’s iPhone factory assets in Karnataka, further consolidating its position in India’s Apple supply chain.
As the Tamil Nadu factory has been "cleared" in the environmental review, Tata's iPhone parts production can continue, and in the context of India's central and local governments hoping to attract more Apple-related investments, its production capacity may be further increased in the future. Driven by Apple's strategy of continuing to reduce its reliance on Chinese production, India's weight on the iPhone manufacturing map is expected to continue to rise, and Tata is likely to continue to play an increasingly critical role in this process.
