The Indian manufacturing industry is undergoing a paradigm shift, and at its core lies the electronics segment. Not anymore confined to being a consumer-based market, the country is fast becoming a powerhouse for manufacturing on the global front. The value of Indian electronics manufacturing has recently surpassed the impressive mark of $130 billion, driven largely by the indigenous demand and a huge push towards self-reliance.
Backed by the structural change where global brands are trying to diversify their manufacturing processes in other regions, recent numbers show that the electronics manufacturing sector has quickly become one of the top categories of goods exported by India, worth ₹3.3 trillion. In this article, we will elaborate on how this manufacturing boom is shaping up, highlight the important segments of the industry, and present the list of the top 20 EMS companies in India. Read on for a detailed analysis!
What is EMS (Electronics Manufacturing Services)?
Electronics Manufacturing Services, commonly abbreviated as EMS, are companies that manufacture, assemble, test, distribute and offer repair/returns services for electronic components and assemblies of original equipment manufacturers. Rather than setting up large manufacturing plants themselves, brand owners outsource these intricate production processes to EMS providers.
This helps in reducing the capital cost of the process, speeding up time-to-market and adjusting the capacity according to market needs. From assembling tiny components on a circuit board to full product assembly, EMS companies are the physical foundation of the modern-day technology brands.
EMS vs ODM vs OEM: Key Differences Explained
| Feature | OEM (Original Equipment Manufacturer) | ODM (Original Design Manufacturer) | EMS (Electronics Manufacturing Services) |
| Owns the Brand | Yes | No | No |
| Product Design | Yes (Typically owns full IP) | Yes (Designs product to sell to multiple brands) | No (Manufactures based on customer’s design) |
| Manufacturing | Optional (Can do in-house or outsource) | Yes | Yes (Core business focus) |
| IP Ownership | Retains full intellectual property | Retains design IP, licenses it to brands | Does not own product IP; focus is process IP |
| Customization | High (Created specifically for their brand) | Low to Medium (Rebranded off-the-shelf designs) | High (Built exactly to customer specifications) |
Why India is Becoming a Global EMS Hub
Here are some of the reasons why India is fast becoming the go-to global destination for electronics manufacturing:
Supply Chain Diversification
The current global shift towards “China+1” supply chain strategy has made India a great destination for multinational brands. Brands across the world are setting up secondary manufacturing bases to avoid sole dependency on one country for components.
Aggressive Financial Support by Government
Great financial support offered by the central government has completely changed the economics of local production. Offering direct financial incentives based on incremental sales has helped in attracting billions in investments from both local and foreign players.
Structural Improvement in Margins
Since electronics assembly has always been a low margin, high volume industry, targeted state-level incentives have improved the margins of local players by 0.6-1%. This small margin cushion has helped Indian players in offering competitive global pricing.
Component Ecosystem
The large-scale manufacturing companies are rapidly diversifying by creating facilities for bare printed circuit boards (PCBs) and camera modules. This move has drastically reduced the dependency on raw imported components from East Asia.
Value Chain Advancement
The local sector is rapidly evolving from basic contract manufacturing to high margin models such as Original Design Manufacturing (ODM) and Joint Design Manufacturing (JDM). This means that local players are now co-designing the latest technologies.

Which EMS Companies Serve Each Segment in India?
Distribution of project works among factories of EMS companies in India depends strictly on structural specifics of factories. For example, mass consumer segments like smartphones and smart TVs are predominantly served by fast-assembly specialists like Dixon, Foxconn and PG Electroplast.
While more complex segments like aerospace, automotive and medical technology are served by precision manufacturing specialists like Kaynes Technology, Syrma SGS, Sanmina and Centum Electronics.
Make in India & China+1 Strategy: Opportunity for Indian EMS
The combination of global supply chain dynamics and favorable domestic policies has set the perfect growth conditions for the national manufacturing industry.
- Global Structural Shift: International companies are consciously shifting from single-source manufacturing models in order to minimize geopolitical risks.
- Export Growth Acceleration: The local manufacturers have successfully graduated from supplying domestic customers with their products to exporting complex hardware to Europe and America.
- Deep Investment: International technology companies are massively investing in infrastructure development, thus turning the local manufacturing facilities into the main export manufacturing plants.
- Advantages of Technology Transfer: Working side-by-side with leading international companies has helped the local manufacturers learn how to manufacture goods using advanced automation equipment and to perform quality testing.
- Effects on Job Creation: This boom in the manufacturing industry has created hundreds of thousands of highly-skilled industrial and engineering jobs.
Challenges Facing EMS Businesses in India
While the industry enjoys significant growth, there are certain structural challenges that need to be solved for future success. These challenges are as follows:
- Import Dependence on Components: Currently, India imports many components used in the electronics production, such as microchips, display panels, and special memory blocks.
- Logistics Infrastructure: Transit within the country between large inland manufacturing facilities and deep-water ports might add extra costs.
- High Requirements to the Working Capital: Large component inventories while having thin operational margins place a huge financial burden on mid-sized companies.
- Need for Skilled Workers: The fast shift towards robotic automation and more complicated SMT lines require permanent requalification of the local workforce.
- Requirements to Industrial Utilities: Clean surge-free electricity and reliable water sources are needed for production of semiconductors and other components.
Outlook for the Future: India as the EMS Export Hub by 2030
The industrial plan for the coming years will make the country not just the regional assembly hub but a self-sufficient global electronics manufacturer. Here are some key trends to watch out for:
- Ambitious Targeting: The domestic electronics production is set to achieve a valuation of $150-155 billion by 2030.
- Ecosystem for Semiconductors Production: The plans include local fabrication and packaging plants that will deliver stable local production of microchips, thus eliminating the need for imports.
- Upstream Engineering Evolution: It is expected that the local businesses will be able to fully transition to full ODM models, thus covering the whole lifecycle of the product from design to distribution.
- Focus on the Green Energy Products: The factories will quickly increase production facilities in order to produce such products as solar inverters and smart chargers for electric vehicles.
- Integration into the Global Supply Chain: By 2030, the Indian manufacturing hubs will be responsible for processing a large share of global electronics exports.
Conclusion
The fast-growing EMS companies in India are the clear indicator of the growing manufacturing capabilities of the nation. Due to the practical policies of the government and financial support, along with the global supply chain diversification, domestic and foreign manufacturing companies are rapidly developing local facilities.
While there are some challenges related to the import of components, the industry is steadily moving towards the design of high-value products, complex automotive electronics, and aerospace systems. As the top twenty market players invest in automated plants and backward integration, India is becoming a strong global EMS hub.
