An Indian pollution regulator has alleged that wastewater discharged from a Tata Electronics factory supplying Apple’s iPhone components has contaminated groundwater used by nearby farmland, according to a regulatory notice reviewed by Reuters. The allegation places one of Apple’s most important manufacturing partners in India under intensified scrutiny at a time when the company is rapidly expanding its production footprint outside China.
The facility at the center of the allegations is located in Hosur, in the southern Indian state of Tamil Nadu, where Tata Electronics manufactures back panels and other components for iPhones. The Tamil Nadu Pollution Control Board has warned that the plant could face a forced shutdown unless Tata provides a satisfactory explanation for the alleged environmental breaches.
The regulator issued a warning notice dated May 25, stating that wastewater from the plant had been improperly managed and had overflowed in a way that contaminated groundwater in nearby agricultural areas. According to the notice, inspections found that Tata had discharged wastewater into a rainwater harvesting pond within the facility. The pond subsequently overflowed, with the resulting discharge affecting “groundwater in the open wells located in the adjacent agricultural lands,” the notice stated.
The allegations follow a series of inspections conducted between December 2025 and May 2026, prompted by repeated complaints from farmers in surrounding areas. Landowners had reportedly raised concerns for months, claiming that wastewater from the facility was affecting their fields and contaminating open wells used for irrigation and local water needs. These complaints led the pollution board to carry out five separate inspections over the period, according to the regulatory findings cited in the notice.
The regulator also stated that Tata Electronics had not taken corrective action despite earlier instructions issued in a letter dated December 23, 2025. In the May 25 notice, the board said prior directions had not been implemented, and that environmental compliance issues at the facility remained unresolved. The notice further warned that authorities were considering stringent enforcement measures, including cutting power supply to the unit and ordering its closure if the company failed to provide an adequate response.
Tata Electronics has disputed the concerns, stating in a response to Reuters that it had commissioned an independent analysis conducted by an accredited laboratory. The company said the study concluded it was “in full compliance with all regulatory norms.” Tata also stated that it remains committed to responsible business practices and environmental protection, adding that it had engaged with pollution authorities, although it did not provide additional details on the nature or outcome of those communications.
Apple, which relies heavily on its suppliers’ adherence to strict environmental standards, has not publicly commented on the matter. The Tamil Nadu state government also did not respond to requests for comment, according to Reuters.
The Hosur plant is part of Tata’s growing role in Apple’s supply chain, which has become central to the technology giant’s broader strategy of diversifying iPhone production beyond China. Tata Electronics is currently the second-largest supplier to Apple in South Asia, behind Taiwan’s Foxconn, and is positioned as a key partner in Apple’s expanding manufacturing base in India.
The allegations add to a series of operational and regulatory challenges that have affected Apple’s supply chain in India in recent years. Production at Tata’s Hosur facility was previously disrupted in September 2024 after a fire halted output of iPhone components. A separate fire incident at a former supplier, Pegatron’s iPhone plant in India, had also temporarily disrupted production in 2023. These events have highlighted the operational vulnerabilities that can arise as Apple accelerates its manufacturing shift to the country.
India’s broader industrial compliance environment has also come under increased scrutiny. According to figures shared by the country’s environment ministry in February, 4.4 percent of more than half a million monitored industries were found non-compliant with environmental standards over the past five years, with around 3,600 facilities shut down during the same period. The data underscores the regulatory pressure faced by manufacturing operators across sectors in India, particularly as industrial expansion continues.
In parallel, India’s importance in global electronics manufacturing has been rising sharply. Research firm Counterpoint has projected that India will account for 26 percent of global iPhone production in 2026, compared with just 6 percent four years earlier. This rapid expansion reflects Apple’s strategic efforts to diversify its production base and reduce dependence on a single country, even as it increases its reliance on Indian suppliers such as Tata Electronics and Foxconn.
The current allegations against the Hosur facility come at a sensitive point in this transition, as regulators, manufacturers, and global technology firms navigate the operational and environmental challenges associated with large-scale industrial expansion. The Tamil Nadu Pollution Control Board’s warning that the unit could face shutdown proceedings if explanations are not provided adds further uncertainty to the situation, as investigations and responses from the company continue.
