Why single-source supply chains break — and how to diversify
Jul 2026 · 7 min read
China+1, dual sourcing and nearshoring: building resilience without doubling your overhead.
A single-source supply chain is efficient right up until it isn't. Tariffs, disruptions, factory closures and demand spikes all hit hardest when there's no plan B.
The cost of single-sourcing
Concentration risk is invisible until it isn't. When your one supplier raises prices, misses a season or gets caught by a tariff, you have no leverage and no fallback — and switching under pressure is expensive.
Strategies that scale
- China+1 — keep your Chinese supplier, add a second country like Vietnam or India.
- Dual sourcing — split volume across two vetted suppliers for the same part.
- Nearshoring — move time-critical lines closer to your market.
- Qualified backups — verify a second source before you need it.
Doing it without doubling overhead
You don't need to fully duplicate your supply base. Qualify backups in advance, keep a modest share of volume flowing to a second source to keep it warm, and you buy resilience for a fraction of the cost of a crisis.
Frequently asked questions
- What is China+1 sourcing strategy?
- China+1 means keeping your existing Chinese suppliers while adding manufacturing in a second country — commonly Vietnam, India or Mexico — to reduce dependence on a single origin and hedge against tariffs and disruptions.
- How do I diversify my supply chain affordably?
- Qualify backup suppliers before you need them, use dual sourcing to split volume across two vetted suppliers, and nearshore only your most time-critical lines. Keeping a second source warm costs far less than a supply crisis.
