China Manufacturing Cost: A Landed-Cost Model
Comparisons between a domestic quote and a China quote usually compare the wrong two numbers. A factory-gate price in Guangdong and a delivered price from a local supplier are not the same quantity, and the difference between them is where the decision is actually made.
The China cost advantage is made of labour content, material sourcing and cluster density — not of a single headline percentage. Whether it survives to your door depends on freight, duty, coordination cost and how much of the part is material rather than labour. This model compares landed cost, not factory price.
What the advantage is actually made of
The important observation is that the advantage is concentrated in labour content. A part that is mostly material — a thick stainless plate, a copper busbar — has less to gain than a part that is mostly touch labour, such as an assembly with many welds, inserts and finishing operations.
| Source | Size of effect | Behaviour |
|---|---|---|
| Labour content | Largest on labour-heavy parts | Shrinks as automation replaces hand work |
| Material sourcing | Modest, and two-way | Domestic mills can be cheaper; imported grades can cost more |
| Cluster density | Real but indirect | Shorter waits for tooling, treatment and hardware, not lower unit prices |
| Overhead structure | Varies widely | A source factory and a trading company differ more than two countries do |
| Compliance and documentation | Can be a disadvantage | Where a certified QMS is required, it has to exist in the supply base |
From factory price to landed cost
| Line | Driver | Typical behaviour |
|---|---|---|
| Factory unit price | Material, machine time, labour | The number buyers compare, and the least complete |
| Export packing | Protection level and crating design | Scales with volume; poor packing costs more in damage than in cartons |
| Inland to port | Distance and load consolidation | Small, but it scales with shipments rather than parts |
| Freight | Mode, volume, weight and lane | Ocean is the default; air freight can erase the advantage on small urgent orders |
| Insurance | Declared value | Small but not zero |
| Duty | Destination and HS classification | Country-specific; verify rather than assume |
| Destination charges | Port, broker, local delivery | Fixed per shipment — significant on small orders |
| Coordination cost | Time-zone management, travel, audits | Usually invisible in the quote and visible in the calendar |
Where the advantage disappears
- Small urgent orders, where air freight and destination charges are spread over few parts.Very heavy parts, where freight scales with mass rather than value.Parts dominated by material cost, where the labour saving has little to act on.
- Programmes requiring a certified quality management system the supply base cannot evidence.Parts with a fast revision cycle, where the transit time adds itself to every engineering change.Situations where the coordination cost is not counted but is real — a time zone costs calendar days on every issue.
How to run the comparison honestly
Take the domestic quote and the China factory quote, add every line in the landed-cost table to the China figure, and then add an allowance for coordination time. Compare the two totals, not the two unit prices.
Then ask a second question: does the difference survive the first engineering change? A programme with three revisions in the first year pays the transit penalty three times, and that is where a small price advantage can turn into a schedule disadvantage without anyone noticing until the third change.
Frequently asked questions
How much cheaper is manufacturing in China?
It depends almost entirely on the labour content of the part, and the honest answer is a range rather than a percentage. Parts that are mostly material gain little; parts that are mostly touch labour gain most. Any single headline number should be treated as a starting hypothesis, not a result.
What does landed cost include that a quote does not?
Export packing, inland transport, freight, insurance, duty, destination charges and the coordination cost of managing the relationship. The factory price is the first line of the calculation, not the answer, and on small orders the remaining lines can dominate it.
When does offshore manufacturing stop making sense?
On small urgent orders, on very heavy parts, and on programmes with a fast revision cycle. In each case the transit time and the fixed per-shipment costs outweigh the manufacturing saving, and the advantage becomes a schedule penalty instead.
Does the China price include quality?
Only if it is specified and inspected. The way to buy quality offshore is to define the acceptance criteria — tolerance standard, first-article report, material certificates, inspection level — and then verify them, rather than assuming a price bracket implies a quality level.
