The Three Contenders for China+1
When global OEMs implement a China plus one strategy for electronics manufacturing, three South and Southeast Asian countries consistently appear on the shortlist: Vietnam, India, and Sri Lanka. Each offers distinct advantages and limitations. This comparison provides an honest, fact-based analysis to help procurement teams make informed decisions.
Full disclosure: TOS Lanka is a Sri Lankan manufacturer. We present this comparison fairly, acknowledging where competitors have advantages, because informed clients make better partners.
Cost Comparison
| Factor | Sri Lanka | Vietnam | India |
|---|---|---|---|
| Average manufacturing labour cost | $150–250/month | $200–350/month | $150–300/month |
| BOI/SEZ tax incentives | Strong (tax holidays) | Strong | Variable by state |
| Electricity reliability | Reliable in EPZs | Improving | Variable |
| Logistics cost to EU | Competitive (Colombo hub) | Moderate | Moderate |
| Logistics cost to Japan | Moderate | Very competitive | Moderate |
Verdict: All three countries offer significant cost advantages over China, Japan, and Western manufacturing. Sri Lanka and India have slight labour cost advantages over Vietnam, but logistics costs vary by destination market.
Quality and Certifications
| Factor | Sri Lanka | Vietnam | India |
|---|---|---|---|
| ISO 9001 certified EMS providers | Multiple (TOS Lanka, GPV, VarioSystems) | Many (Samsung, LG subcontractors) | Many (Syrma SGS, Dixon, Kaynes) |
| Japanese quality culture | Strong (Japanese-owned factories) | Growing (Japanese FDI) | Limited |
| Medical device (NMRA/CDSCO) | Available (TOS Lanka NMRA-approved) | Limited | Growing (CDSCO) |
| Workforce skill level | High (92% literacy, Japan-trained) | Growing rapidly | Variable by region |
Verdict: Sri Lanka's advantage is quality density — fewer but more mature EMS providers with deep expertise. India offers scale. Vietnam offers proximity to Northeast Asian supply chains.
EMS Capability Depth
| Capability | Sri Lanka (TOS Lanka) | Vietnam (typical EMS) | India (typical EMS) |
|---|---|---|---|
| SMT Assembly | ✅ Panasonic lines | ✅ | ✅ |
| THT Assembly | ✅ | ✅ | ✅ |
| Box Build | ✅ | ✅ | ✅ |
| Conformal Coating | ✅ | Variable | Variable |
| Wire Harness | ✅ Automotive grade | Limited | Growing |
| Inductive Components | ✅ Unique | ❌ | Rare |
| BGA Rework + X-ray | ✅ | Variable | Variable |
Verdict: For breadth of capability under one roof, Sri Lanka (specifically TOS Lanka with 9 service lines) is unmatched. India excels in scale. Vietnam excels in high-volume consumer electronics for Northeast Asian brands.
Ideal Use Cases by Country
Choose Sri Lanka When:
- You need high-mix, low-to-medium volume manufacturing with Japanese quality standards
- Your product requires multiple processes (SMT + wire harness + coil winding + box build)
- You need medical device or automotive electronics with full traceability
- You value a single-source partnership over managing multiple vendors
- You are a European or Japanese OEM seeking a culturally compatible manufacturing partner
Choose Vietnam When:
- You need high-volume consumer electronics manufacturing at scale
- Your primary market is Northeast Asia (Japan, South Korea)
- You want proximity to existing Samsung/LG supply chain ecosystems
- Your product is relatively standardised with minimal custom processes
Choose India When:
- You need massive production scale (100,000+ units)
- Your primary market is the Indian domestic market
- You want access to India's growing electronics design talent pool
- You are building for the Indian automotive or telecommunications sector
The Smart Approach: Portfolio Diversification
The most resilient supply chain strategies don't pick a single alternative to China — they build a portfolio. Many sophisticated OEMs use a combination:
- China: High-volume standard products (scale advantage)
- Sri Lanka: High-reliability, multi-process products (quality + consolidation advantage)
- Vietnam or India: Regional market-specific production (proximity advantage)
This portfolio approach provides resilience against country-specific risks while optimising cost and quality for each product type.
