Apple's iPhone is probably the most important technological innovation of this century.
In 2007, when Steve Jobs unveiled the original iPhone, jaws dropped. Today, the iPhone has become a device so common that it's almost unremarkable. That said, the iPhone represents one of the most complex global supply chains in modern manufacturing. While each unit bears the inscription "Designed in California, Assembled in China," the reality involves components and expertise from more than 40 countries.
Ongoing geopolitical tensions, particularly the US-China trade disputes sparked by Donald Trump's tariffs, have brought unprecedented attention to this intricate supply network. These challenges have pushed Apple to rethink its manufacturing strategy, leading to a possibly increased diversification of its supply chain.
Key Components and Their Origins
The Heart: Processing Power
Apple designs its chips in the USA, but Taiwan Semiconductor Manufacturing Company (TSMC) produces 100% of Apple's A-series (iPhone and iPad) and M-series (Mac) processors. Taiwan's dominance in advanced semiconductor manufacturing has become a crucial geopolitical consideration, prompting the US CHIPS Act to boost domestic production. TSMC controls about 54% of the global foundry market, with Samsung following at 17%.
The Eyes: Camera Technology
Japan's Sony commands approximately 45% of the global image sensor market, making it the primary supplier for iPhone cameras. LG Innotek from South Korea provides about 30% of iPhone's camera modules. Japan's leadership in high-end imaging sensors makes it irreplaceable in smartphone photography, with Japanese companies controlling nearly 70% of the global market.
The Face: Display Technology
Samsung Display dominates iPhone's OLED supply with approximately 60% of orders, while LG Display holds about 25%. Chinese manufacturer BOE Technology recently secured about 15% of orders, signalling Apple's interest in diversifying its display supply chain. South Korean manufacturers still control roughly 85% of the global OLED market.
The Memory: Storage Solutions
Samsung leads the iPhone's memory supply with 35% of NAND flash memory, followed by Japan's Kioxia at 20%. In RAM, Samsung and SK Hynix together provide about 75% of iPhone's requirements. South Korean companies control approximately 60% of the global memory chip market.
The Soul: Software & Security
Apple maintains 100% control over iOS development and its security architecture in the USA. The App Store generates about $85 billion in annual revenue, with developers from over 175 countries. Apple's privacy features and security chips are designed in-house but manufactured by TSMC.
The Body: External Components
Chinese manufacturers produce about 95% of iPhone's precision-machined aluminium frames. Corning, based in the USA, supplies nearly 100% of iPhone's Gorilla Glass. The supply chain for speciality metals spans 20+ countries, with no single nation controlling more than 30% of any critical material.
The Brains: Sensor Technology
Germany's Bosch supplies approximately 40% of iPhone's motion sensors, while STMicroelectronics (Switzerland/Italy) provides about 35% of its gyroscopes. Qualcomm currently holds 100% of iPhone's modem business, though Apple is developing in-house solutions. Broadcom (USA) and NXP (Netherlands) together supply about 80% of wireless chips.
Final Assembly
Foxconn handles about 70% of iPhone assembly, with operations split between China (80%) and India (20%). Pegatron and Wistron together manage the remaining 30%, with increasing capacity in India. China still accounts for approximately 85% of total iPhone assembly, though this percentage is decreasing annually.
Strategic Shifts
Apple's manufacturing strategy is evolving rapidly. India now produces about 7% of iPhones, with plans to reach 25% by 2025. Vietnam handles 20% of AirPods production and is expanding into other Apple products. This diversification aims to reduce single-country manufacturing dependence, with a target of reducing China's share to below 65%.
This global manufacturing ballet requires precise coordination among hundreds of suppliers, making the iPhone a prime example of globalisation's complexity and interdependence. As geopolitical tensions rise, Apple's supply chain adaptability becomes increasingly crucial for maintaining production stability.
The iPhone's journey from raw materials to finished product showcases both the benefits and vulnerabilities of global supply chains, as well as the delicate balance between innovation, cost, and geopolitical considerations.
