"Don't keep everything in China" sounds prudent, which is exactly why it rarely gets tested against a calculator. This article is for companies buying $500,000+ a year from China who are weighing a second sourcing country, and it works through what China+1 genuinely protects against, what it costs in real money, and the conditions under which it becomes two problems instead of one.
What China+1 is, and why everyone is talking about it
China+1 is not leaving China. It is adding a second manufacturing origin while keeping the first, so that a shutdown, a tariff or a political decision in one jurisdiction does not stop your entire flow of goods.
The strategy went mainstream for concrete reasons: trade wars and tariffs, pandemic-era factory and port closures, logistics disruption. All three are real. The question is not whether the risk exists, but whether a second country is what removes it.
The central illusion: diversification that isn't
The most common error is assuming a Vietnamese factory is independent of China. Mostly, it is not.
- Components and raw materials. Vietnamese, and often Indian, plants overwhelmingly buy sub-assemblies, fabric, metal and electronics from China — the structure of that transshipment trade is well documented. A Chinese supplier stoppage halts both of your chains at once.
- The same lane. Cargo from both countries moves through the same congested hubs and the same Red Sea diversion — see the Red Sea and Suez.
- The same calendar. Tết in Vietnam falls close to Chinese New Year, and regional production stops in sync — see China's production shutdowns.
- The same typhoon season, and the same exposure to the container market.
So what China+1 genuinely protects against: tariffs and rules of origin, dependency on a single factory, and a regulatory decision in one country. Against logistics disruption or a broad stoppage in Chinese industry — barely at all.
What China+1 duplicates
This is the part missing from the presentations:
- Tooling. A second mould is another $10,000–30,000, and it needs to be yours rather than the factory's (see mould cost and ownership)
- Specification and golden sample — two sets that must match to the parameter, or you get two different products under one SKU
- The QC protocol — inspections, labs and AQL criteria in two countries
- Certification — documents attach to the manufacturer, so changing factory often means retesting (see certification for goods from China)
- Administration — two contracts, two banking corridors, two sets of compliance, two teams
- And above all, volume. Splitting 10,000 units into two runs of 5,000 loses the volume discount at both factories. Given how non-linear the MOQ curve is, that frequently costs more than the 5–10% you hoped to gain
China+1 is not a way to save money. It is insurance, and like any insurance it carries a premium. The only question is whether the risk it covers costs more than the premium does.
When China+1 is justified
- $1M+ a year in the category — enough for the duplicated fixed costs to amortise acceptably
- A US target market with tariff and origin exposure — here it is not insurance but a condition of trading
- One SKU carrying most of your revenue — a single factory stopping kills the business, not the quarter
- A regulated category where a missed delivery means losing a tender or a retail contract
- A category where the second country is structurally strong — textiles and footwear in Vietnam, chemicals and engineering in India (see the four-country comparison)
When it just doubles the problems
- Under $500,000 a year — fixed costs consume the rationale
- Many SKUs in small quantities — administration grows faster than the benefit
- No quality control capability of your own — two uncontrolled factories are worse than one controlled factory
- Tooling-heavy categories — duplicating the tooling will not amortise at your volume
- You have not yet got the process right with the first factory — the most common case of all: China+1 attempted instead of fixing the sourcing you already have
Three working alternatives to relocating
For most mid-size importers the right answer is not a second country but a smaller, cheaper form of the same insurance:
- A second factory inside China. The cheapest real diversification: different province, different owner, same standard. It removes single-plant dependency while keeping the ecosystem, the price and the lead time.
- Dual-source only what is critical. Not the whole range — one or two SKUs, or the single component everything else depends on. Leave the rest single-sourced.
- A qualified backup held dormant. Factory vetted, sample approved, price agreed — but no orders placed. It costs a few thousand a year and activates in three weeks instead of three months.
The third is the most underrated: most of the cost of China+1 is not manufacturing but qualification time, and that is precisely the part you can pay for in advance.
How to do it properly, if you do it
- Qualify before you need it — under pressure you will pick whoever is free, not whoever fits
- Keep the second source at 10–20% of volume, not 50% — enough to keep the line warm and the price comparable
- Own the tooling at both, or your "second source" is yours in name only
- One specification across both factories, with the same golden sample and the same acceptance criteria (see sample types and the golden sample)
- Check where the components come from in the second country — this is where the imaginary diversification hides
- Vet the second factory with the same protocol as the first — see our verification protocol
The honest conclusion
China+1 is the right strategy for buyers who can afford it and an expensive mistake for those who cannot. The threshold is not set by how much you want to reduce risk, but by the volume at which duplicated costs make sense.
If you do not yet own your tooling, have no approved golden sample and do not inspect before the balance payment, that is your actual risk — not geography. Getting one factory under control reduces risk further, and far more cheaply, than a second factory in a second country.
Cost your own case
We qualify backup factories in advance — inside China and beyond it — hold a single specification across all sites, and vet the second supplier with the same protocol as the primary. Seven years, 340+ verified suppliers, 3,500+ deliveries; projects in our case studies.
