The strategic thesis
India has built genuine scale in electronics assembly, led by mobile handsets and supported by production-linked incentives that made the unit economics work for global brands and their contract manufacturers.
The value captured domestically remains modest because most components are imported. Component and sub-assembly localisation is the defining challenge of the next phase.
For global entrants the practical question is not whether India can assemble at quality — it demonstrably can — but how to structure supply chains while the component ecosystem is still forming.
What the data says
Production-linked incentives anchor the current electronics investment wave.
Mobile assembly leads volume and export growth.
Component sourcing remains the largest value leakage.
Sub-assembly and precision component suppliers are the scarce layer.
Tamil Nadu, Uttar Pradesh and Karnataka lead electronics clusters.
Global brands increasingly use India as an export base, not only for domestic demand.
Strategic context
India is now the second-largest mobile phone manufacturer in the world. PLI for IT hardware, components, and white goods is deepening the local value chain.
EMS leaders are scaling Tier-2/3 supplier ecosystems across Tamil Nadu, Karnataka, Andhra Pradesh and UP.
Electronics value chain — where India stands
01 · Final assembly
Mature and competitive; quality and throughput are proven.
02 · Sub-assembly
Developing; display, camera and battery modules are localising.
03 · Components
Thin; passives, connectors and precision parts largely imported.
04 · Materials and equipment
Earliest stage; dependent on imports and technology partnerships.
Leading electronics manufacturing clusters in India
| State | Cluster | Strength |
|---|---|---|
| Tamil Nadu | Sriperumbudur, Hosur | Deepest supplier base and skilled workforce |
| Uttar Pradesh | Noida, Greater Noida | Handset assembly scale and domestic market access |
| Karnataka | Bengaluru, Mysuru | Design-adjacent electronics and higher-value products |
| Andhra Pradesh | Sri City, Tirupati | Port proximity and plug-and-play parks |
| Gujarat | Sanand, Dholera | Semiconductor adjacency and industrial infrastructure |
Why components are harder than assembly
Assembly economics respond quickly to incentives and labour cost. Component manufacturing responds to process know-how, capital intensity and volume certainty — none of which an incentive scheme delivers on its own.
The mechanism that works is anchor demand: a large assembler committing multi-year volumes to a domestic component supplier, often with technology transfer from an established global player. Where that commitment is absent, localisation targets slip.
Designing for a forming ecosystem
Entrants should assume dual sourcing for the first three years — a domestic supplier being qualified alongside an established import route — rather than planning for immediate full localisation.
Supplier development is a line item, not an assumption. Manufacturers that fund quality systems, tooling and engineering support for tier-2 suppliers reach localisation targets; those that only issue purchase orders do not.
Qualify domestic suppliers in parallel with existing import routes.
Budget for tooling, quality systems and resident engineering support.
Multi-year commitments are what unlock component capital investment.
Cluster choice drives ramp speed
Tamil Nadu's supplier density shortens ramp time materially compared with greenfield locations, even where other states offer stronger headline incentives.
Port proximity matters more than it appears in feasibility models while components are still imported. Andhra Pradesh and Tamil Nadu score well on this dimension; landlocked clusters carry a persistent logistics penalty.
What to do now
- →Plan dual sourcing for the first three years rather than assuming immediate localisation.
- →Budget explicitly for supplier development, including tooling and resident quality engineering.
- →Weight cluster selection toward existing supplier density and port proximity, not headline incentives.
- →Secure anchor volume commitments before expecting domestic component capital investment.
- →Sequence localisation from sub-assembly toward components rather than attempting both at once.
The decade ahead
Sub-assembly localisation — displays, camera modules, batteries and enclosures — will progress faster than discrete component manufacturing through 2028.
India's role as an electronics export base will continue expanding beyond handsets into IT hardware, wearables and industrial electronics.
What matters most
- 1Assembly scale is proven; component depth is the current constraint.
- 2Anchor demand, not incentives alone, unlocks component investment.
- 3Supplier development must be funded as a programme line item.
- 4Supplier density and logistics beat headline incentives on ramp speed.
Frequently asked
Is India competitive for electronics assembly?+
Yes — quality and throughput are proven at scale, particularly in handsets, supported by production-linked incentives.
What limits domestic value capture?+
Most components are still imported, so a large share of product value leaves the country despite local assembly.
Which state is best for electronics manufacturing?+
Tamil Nadu offers the deepest supplier base; Uttar Pradesh leads handset assembly scale and Andhra Pradesh offers port-proximate plug-and-play parks.
How long does supplier localisation take?+
Plan on three years of dual sourcing while domestic suppliers are qualified and supported.
What unlocks component manufacturing investment?+
Multi-year anchor volume commitments from assemblers, usually combined with technology transfer partnerships.
