Tata Electronics was described as “central” to Apple’s push to diversify iPhone production beyond China and as Apple’s second-biggest supplier in South Asia after Foxconn.
2
The Hosur plant makes “back panels and other” components for iPhones, according to the pollution regulator’s notice and Reuters’ reporting.

Reuters said the warnings came from a “previously unreported regulatory notice dated May 25” (described as a “three-page notice”) and referenced an earlier Pollution Control Board letter dated December 23, 2025.

The report noted that farmland owners had complained to the Tamil Nadu Pollution Control Board for months before the regulator’s inspections began.

Apple’s procurement standards were described as “strict,” particularly regarding how suppliers handle wastewater.
India's pollution watchdog has threatened to shut down a Tata Electronics factory in Hosur, Tamil Nadu, that makes components for Apple iPhones. The Tamil Nadu Pollution Control Board alleges that wastewater from the plant contaminated groundwater used by nearby farms, according to Reuters.
The regulator issued a three-page notice on May 25 warning that the facility could face a power cut and forced closure. Tata Electronics disputes the findings, saying an independent lab found the company "in full compliance with all regulatory norms."
Five Inspections Reveal Wastewater Flowing Into Farm Wells
State inspectors visited the Hosur plant five times between December 2025 and May 2026, Reuters reported. Each visit pointed to the same problem: Tata discharged wastewater into an on-site rainwater harvesting pond. That pond overflowed into nearby agricultural land, contaminating open wells that local farmers depend on.
The board first issued corrective instructions in a letter dated December 23, 2025. According to Business Standard, the regulator says Tata failed to complete those fixes. Local farmland owners had been complaining for months before inspections even began.
Regulator Demands Tata Explain Why Plant Should Stay Open
The TNPCB issued a show-cause notice on May 15, giving Tata 15 days to respond. The board asked Tata to explain why regulators should not cut the plant's power supply and shut it down entirely, Business Standard reported. The three-page follow-up notice on May 25 formalized those demands.
Tata Electronics fired back, saying it hired an accredited independent laboratory to test its compliance. The company said results showed it met all regulatory standards. "We are committed to responsible business practices and protection of the environment," the company told Reuters. Apple did not respond to inquiries.
Tata Is Central to Apple's Push Away From China
The Hosur plant makes back panels and other iPhone components. It sits at the heart of Apple's strategy to move manufacturing out of China and into India. Reuters described Tata Electronics as "central" to that effort. Tata is Apple's second-biggest supplier in South Asia, behind only Foxconn.
The plant had a history of regulatory friction even before this crisis. In December 2023, inspectors found Tata had added machinery and expanded production sheds without the required permits, according to records from India's National Green Tribunal. The facility's approved production capacity stands at 50,000 units per day.
A Shutdown Would Ripple Through Apple's Supply Chain
If regulators cut power to the Hosur plant, iPhone component production would stop immediately. Because Tata is the second-largest Apple supplier in the region, a halt could bottleneck assembly lines elsewhere in India, according to The Economic Times. Apple's supplier code of conduct is known to be strict on wastewater handling.
Farmers in the Krishnagiri district face long-term harm if the groundwater contamination is confirmed. Tamil Nadu is also trying to balance its ambition to be a global manufacturing hub against the need to protect local agricultural communities, Business Standard noted. The next move rests with Tata's formal response to the board.
