# China plus one sourcing: how to add a second source without losing the first

China plus one means keeping your China suppliers and adding a qualified second source in another country, usually India or Vietnam, so price, capacity and delivery are protected by two lanes instead of one. It works best when you pick the right products to move first, compare landed cost rather than factory price, and plan tooling and qualification as a 12 to 20 week project.

## Key takeaways

  * China plus one is a second lane, not an exit. Most buyers keep China for the bulk of volume at first.
  * Move products where the new country is strong: metals, castings, forgings, textiles, leather and home goods often suit India.
  * Compare landed cost per unit, including duty, freight and inspection, never the ex-works price alone.
  * Decide early whether to transfer moulds and dies or build a second set. It sets your timeline.
  * Plan 12 to 20 weeks for most engineered parts: search, audits, samples, a golden sample and a pilot lot.

## Why buyers add a second lane

Single-country sourcing works until something moves: a tariff change, a port closure, a festival shutdown that runs long, a supplier that doubles its MOQ. A second qualified source turns each of those from a crisis into a volume shift.

The reasons buyers give us most often are:

  * **Duty exposure.** US importers in particular face additional duties on many Chinese goods on top of the general rate. Rates change often, so check the Chapter 99 provisions for your code in the [US Harmonized Tariff Schedule](https://hts.usitc.gov/) before you model anything.
  * **Forced-labour compliance.** Since 21 June 2022, US Customs and Border Protection has applied a rebuttable presumption that goods made wholly or in part in Xinjiang, or by entities on the UFLPA Entity List, are made with forced labour and may not be imported. High-priority enforcement sectors include apparel, cotton, silica-based products such as polysilicon, tomatoes, aluminium, PVC and seafood and, since the August 2025 strategy update, caustic soda, red dates, copper, lithium and steel.
  * **Capacity and negotiation.** Two lanes give you real quotes from two countries and somewhere to put a volume spike.

None of this means leaving China. Its supplier depth, speed and component ecosystem are hard to match. The goal is choice.

## Which products to move first

Start with parts where the second country is already strong and the transfer is simple. India’s depth is in metals and materials-heavy processes: castings, forgings, machined parts, sheet metal and welded frames, fasteners, hand tools, textiles and apparel, leather goods, brass and home décor, ceramics and many packaging formats. Vietnam is strong in electronics assembly, furniture, footwear and apparel.

Signal | Good first mover | Harder mover  
---|---|---  
Bill of materials | Few components, mostly one material | Many bought-in components from Chinese sub-suppliers  
Tooling | Simple dies or moulds, or tools near end of life | New, complex multi-cavity tools  
Volume | Steady, forecastable | Spiky, fast-changing designs  
Specification | Clear drawing, measurable requirements | “Same as last time” with no written standard  
Duty position | Large difference between origins | Little or no difference  
  
The [second-source planner](https://sourcesquid.co/tools/second-source-planner/) scores your parts on these signals and suggests how to split volume. The [India cluster finder](https://sourcesquid.co/tools/india-cluster-finder/) shows where in India each process runs at scale.

## Compare landed cost, not factory price

A new supplier’s ex-works price is the least useful number in a China plus one decision. Compare the full landed cost per unit for both lanes:

Cost element | Why it differs between lanes  
---|---  
Unit price and MOQ | Labour, material prices, scale  
Tooling | New tools, or transfer and re-qualification  
Inland freight to port | India’s factories can be further from the port  
Ocean freight and transit time | Different routes, carriers and transhipment  
Import duty | Different origin, and possibly different additional duties  
Inspection and QA | Audits, first articles and more inspections in year one  
Inventory | Longer transit means more stock on the water  
  
The [landed cost calculator](https://sourcesquid.co/tools/landed-cost/) applies each market’s duty rules, and the [teardown cost calculator](https://sourcesquid.co/tools/teardown-cost/) builds a should-cost for the part so you can tell whether a quote is fair. See the [landed cost guide](https://sourcesquid.co/intelligence/landed-cost-guide/) for the method.

## Moulds and dies: transfer or duplicate

Tooling usually decides the timeline. You have three options:

  1. **Transfer the existing tool.** Cheapest, but the China lane stops while the tool ships and is trialled, and an older tool may need refurbishment. Check that you own it and can move it: see [tooling and mould ownership](https://sourcesquid.co/intelligence/tooling-and-mould-ownership/).
  2. **Build a second tool in the new country.** Both lanes run in parallel. Costs more, and the new tool needs its own sampling and approval.
  3. **Build the second tool in China and ship it.** Sometimes faster and cheaper for complex moulds, but the new factory must accept a tool it did not build.

A useful rule: duplicate tools for your highest-volume parts so both lanes can run; transfer tools for low-volume parts at the end of a run.

## A realistic plan: 12 to 20 weeks

Weeks | Stage | Output  
---|---|---  
1–2 | Teardown and cost model | Process chain, should-cost, target landed cost  
2–5 | Factory search and RFQ | Named longlist, 3 to 5 comparable quotes  
5–7 | Audits | Scored audit reports for 2 to 3 factories  
6–14 | Tooling and samples | First-article inspection report, golden sample  
14–20 | Pilot lot | In-line and pre-shipment inspection, first shipment  
  
Plan around the calendar too. A pilot that lands in the weeks around Diwali in India, or Chinese New Year in China, loses time on both lanes. The [festival and holiday planner](https://sourcesquid.co/tools/festival-and-holiday-planner/) shows the working days you actually have.

## Worked example: an aluminium lamp housing

A US lighting brand buys a pressure die-cast aluminium housing from Ningbo: 30,000 a year, powder coated, one two-cavity die that is two years old.

**Decision.** Keep Ningbo at 70% of volume; add an Indian die-caster for 30%. The part is a single material with simple machining, a good first mover.

**Where.** The Atlas lists [aluminium and zinc die castings](https://sourcesquid.co/india-atlas/products/aluminium-zinc-die-castings/) in Rajkot, Pune, Chennai, Faridabad, Aligarh and Hosur, with the die and samples in 6 to 8 weeks and production in 4 to 6 weeks.

**Tooling.** Duplicate rather than transfer, because the Ningbo die runs at full capacity. The new die is built in India to the same part drawing, not copied from the old tool.

**Cost comparison (per unit, landed in the US).** The brand compared both lanes using the same freight assumptions and each origin’s duty position from the HTS, including Chapter 99 additional duties. The decision rule was simple: the India lane had to land within 5% of the China lane after amortising the new die over two years of the 30% share.

**Timeline.** 16 weeks from brief to first shipment, of which the die and first-article approval took 8.

## Where China plus one projects stall

The same few problems slow most second-source projects:

  * **An incomplete technical pack.** The China supplier has years of unwritten knowledge. Write down tolerances, materials, finishes, packaging and test methods before the new factory quotes.
  * **Sub-components still from China.** If the new lane depends on Chinese components, you have added a factory, not a lane. Map the bill of materials to its origins.
  * **Approving on samples alone.** A pilot lot under production conditions finds problems that hand-finished samples hide.
  * **Asking the incumbent to help.** Tell your China supplier about the second lane honestly, but do not expect it to transfer know-how to a competitor.
  * **Rules of origin.** Duty savings depend on where the goods are legally made, not where they ship from. Minimal processing in a second country does not usually change origin.

## Running two lanes well

  * **One specification, two suppliers.** Both factories work to the same drawing, the same [golden sample](https://sourcesquid.co/intelligence/golden-sample-and-sample-approval/) and the same [AQL plan](https://sourcesquid.co/intelligence/aql-sampling-explained/).
  * **Scorecards every month.** Quality, on-time delivery and responsiveness, shared with both suppliers.
  * **Real volume for the new lane.** A second source given 5% of volume and no forecast will not stay qualified for long.
  * **Review the split twice a year.** Move share based on performance, cost and duty changes, not on who complained loudest.

### What is China plus one sourcing?

China plus one is a sourcing strategy where a buyer keeps its China suppliers and adds a qualified second source in another country, such as India or Vietnam, so volume, pricing and delivery are protected by two supply lanes instead of one.

### Is India or Vietnam better for China plus one?

It depends on the product. India is strong in metals, castings, forgings, machined parts, textiles, leather, home goods and many chemicals. Vietnam is strong in electronics assembly, furniture, footwear and apparel, often with supply chains linked to China. Compare named factories and landed cost for your part.

### How long does a China plus one move take?

For most engineered parts, 12 to 20 weeks from brief to first production shipment: factory search, audits, samples, a golden sample and a pilot lot. Tooling lead time is usually the longest single step.

### Should I move my moulds from China to India?

Transferring existing tools saves money but stops the China lane while the tool is in transit and being trialled. Building a second set costs more but lets both lanes run in parallel. Many buyers transfer older tools and duplicate the tools for their highest-volume parts.

### Will my costs go up with a second source?

Often the unit price in the new lane is close to China for labour- and metal-intensive parts and higher for parts that depend on China's component ecosystem. Add qualification, tooling and inspection costs, and compare on landed cost including any duty differences.
