The assembly lines are operating in the industrial areas outside of Chennai. Employees are transporting iPhone parts through stations that, in general, resemble what you’d expect from a facility running in accordance with Apple’s specifications: spotless floors, regulated conditions, and employees wearing uniforms provided by the firm. Apple has made no secret of the fact that it is growing its presence in India. There is a headcount. The structures are present. The output is rising.
Less obviously, there is also a cost structure that is far more than what the identical operations cost in Shenzhen. Analysts monitoring Apple’s supply chain estimate that Indian manufacture costs five to eight percent more than comparable Chinese production, and the reasons for this premium are fundamental enough to withstand band-aid solutions.
Let’s start with the individual parts. Although India does a good job of handling assembly, the essential components—camera modules, display panels, and batteries—are still mostly made in China and must be transported to Tamil Nadu before they can be assembled. The labor cost benefits that once made India a desirable option are diminished by ocean freight and Indian import duties. Because so much of the input costs are still of Chinese origin, the promise of reduced labor costs has not yet come to pass.
The yield issue comes next. Early production runs in India have shown how tough it is to achieve Apple’s extremely strict tolerance requirements without Shenzhen’s decades-long manufacturing knowledge. In some manufacturing windows, yield percentages for specific components, like as casings made at Tata Electronics plants, have reportedly hovered around 50%. This indicates that about half of the parts made are unfit for use since they don’t match the required standards. Every faulty casing costs money twice: once for production and once for replacement.
Another topic of contention that receives insufficient attention is labor organization. Extended shifts—two twelve-hour rotations that enable round-the-clock production with comparatively minimal staffing—have been used in Chinese manufacturing operations, especially under Foxconn’s management in Shenzhen and Zhengzhou. That model is not equally accommodated by Indian labor legislation. To achieve the same continuous throughput, three eight-hour shifts require more employees overall, more overhead for training, and more management coordination. Although it increases expenses, the difference is not overwhelming.
Knowledge transfer is arguably the most underrated task. It takes technical know-how to operate complex electronics assembly machinery correctly, diagnose issues, and maintain quality at scale. Due in part to delays in equipment export permissions from Chinese authorities, Chinese engineers who are familiar with Foxconn’s procedures have not been readily available to convey that knowledge to Indian plants. Apple is unable to completely engineer around the geopolitical aspect of that friction.
The change is not being stopped by any of this. Apple continues to develop Indian capacity, even at a premium, for strategic reasons, including supply chain diversification, tariff vulnerability, and geopolitical risk. However, it serves as a helpful reminder that no matter how much money and effort is put into it, manufacturing ecosystems that took thirty years to establish in Shenzhen don’t move smoothly in a few years.
