The strategic thesis
Supply chain diversification is no longer a contingency exercise. Tariff exposure, customer requirements and shareholder pressure have converted it into committed capital with board-level timelines.
India competes for this capital against Vietnam, Mexico, Thailand and others. It wins on domestic market size, engineering depth and scale headroom; it loses time on component availability and approval speed.
The companies executing well treat India as one node in a redesigned network rather than a like-for-like replacement of a Chinese plant — the product, the supplier base and often the design have to adapt.
What the data says
Diversification has shifted from scenario planning to funded programmes.
Downstream customers increasingly mandate non-China sourcing options.
India's main competitive weakness against Vietnam on assembly ramp.
India's domestic demand is a differentiator no competing location matches.
Realistic horizon for a substantive dual-source manufacturing footprint.
Successful moves adapt product and supplier base rather than copying the Chinese line.
Strategic context
China+1 is a structural diversification — not a tactical shift. Global manufacturers are rebalancing capacity across electronics, components, pharma, chemicals and industrial goods toward India and ASEAN.
India's PLI-backed scale, talent depth, domestic demand and port infrastructure make it the leading destination for the next decade of manufacturing relocation.
Four-step China plus one execution sequence
01 · Exposure mapping
Identify single-source dependencies by part, not by supplier or country.
02 · Node design
Decide which products move where, based on component availability and market proximity.
03 · Supplier development
Qualify and fund the tier-2 base; the step most often under-resourced.
04 · Dual running
Operate both sources through a full demand cycle before committing to a switch.
India versus alternative diversification locations
| Factor | India | Vietnam | Mexico |
|---|---|---|---|
| Domestic market | Very large | Small | Moderate |
| Component ecosystem | Developing | Strong for electronics | Strong for automotive |
| Engineering depth | Very strong | Limited | Moderate |
| Scale headroom | Very high | Constrained | Moderate |
| Approval speed | State-dependent | Fast | Moderate |
| Proximity to US market | Distant | Distant | Adjacent |
Why like-for-like relocation fails
A Chinese plant is the product of two decades of supplier co-location, process refinement and workforce specialisation. Recreating it elsewhere in eighteen months is not a plan.
Companies that succeed accept design changes — different components, different tolerances, sometimes different product variants for different regions — rather than insisting on an identical bill of materials in a market that cannot yet supply it.
The tier-2 problem is the whole problem
Final assembly capability is rarely the constraint. What slows programmes is the second and third tier: precision machining, specialised plastics, connectors, surface treatment and testing services.
Manufacturers that send engineers to sit with domestic suppliers, fund tooling and underwrite quality systems achieve localisation. Those that issue purchase orders and wait do not.
Supplier-embedded engineers are the single highest-return intervention.
Fund tooling directly rather than expecting suppliers to finance it.
Extend the enterprise quality management system to critical tier-2 partners.
Market access plus engineering depth
India offers something no competing diversification location does: a domestic market large enough that the plant has a business case even if export volumes disappoint.
Combined with engineering depth that supports local design adaptation, this makes India the strongest choice for products where local variants matter and volumes justify a dedicated supply chain.
What to do now
- →Map single-source exposure at part level, not supplier or country level.
- →Accept product and component redesign rather than forcing an identical bill of materials.
- →Fund resident engineering and tooling support for critical tier-2 suppliers.
- →Run dual sources through a full demand cycle before switching.
- →Evaluate India on domestic market plus engineering depth, not cost alone.
The decade ahead
Component localisation will improve steadily but unevenly, favouring sectors with existing anchor demand such as automotive and consumer electronics.
Multi-node networks, rather than single-country replacements, will become the standard resilient structure.
What matters most
- 1Diversification is funded and time-bound, not hypothetical.
- 2Tier-2 supplier development is the binding constraint.
- 3Like-for-like relocation of a Chinese plant reliably fails.
- 4India's domestic market makes the business case resilient.
Frequently asked
What is the China plus one strategy?+
Maintaining Chinese manufacturing while building substantive capacity in at least one additional country to reduce concentration, tariff and geopolitical risk.
How long does a China plus one move take?+
Around three years for a substantive dual-source footprint including supplier qualification, not the twelve to eighteen months often assumed.
Where does India beat Vietnam?+
Domestic market size, engineering depth and scale headroom; Vietnam currently leads on electronics component availability and approval speed.
What slows India programmes most?+
Tier-2 supplier availability — precision machining, connectors, specialised plastics and treatment services.
Should the product design change?+
Usually yes; insisting on an identical bill of materials in a forming supplier ecosystem is the most common cause of delay.
