A factory can have 300 employees, ISO certification and a large production hall — and still be the wrong supplier for your project.
When overseas buyers evaluate a Chinese factory, they often start with the same questions:
How large is your factory?
How many employees do you have?
Do you have ISO certification?
Can you send me your product catalogue?
These questions are not useless.
But by themselves, they tell you very little about whether a supplier can actually deliver your project.
After years of working around Chinese manufacturing and industrial procurement, I have learned to look at supplier capability in a different order.
1. Have They Delivered Projects Similar to Yours?
I don't start with:
“How many projects have you completed?”
I ask:
“What have you actually delivered that is similar to this project?”
There is a big difference.
Imagine a supplier showing you 200 completed pump projects.
That sounds impressive.
But if most of those projects involved standard water-service pumps, the number tells you very little about its ability to engineer and deliver a customized chemical process pump.
Relevant experience matters more than total experience.
When evaluating similar projects, I look for similarities in:
Industry
Application
Process
Capacity
Operating conditions
Technical complexity
Export requirements
And then I want to understand exactly what role the supplier played.
Did they design the system?
Manufacture the core equipment?
Integrate equipment from different suppliers?
Or simply supply one component?
A supplier may show ten highly relevant projects, but if it only supplied one small component in each, that experience should not be treated the same as having designed and delivered the complete system.
The first question is not:
“What do you make?”
It is:
“What have you delivered that looks like my project?”
And then:
“What exactly were you responsible for?”
2. Is the Engineering Capability Really In-House?
For customized industrial equipment, engineering capability can be more important than factory size.
I want to know:
Who designs the equipment?
Who answers technical questions?
Who prepares the drawings?
Who develops the BOM?
Who is responsible for engineering changes?
Who makes technical decisions when the project changes?
Sometimes a supplier uses external engineering partners.
That is not necessarily a problem.
The important question is:
Who owns the engineering responsibility?
If the supplier cannot clearly explain who is responsible for the design and technical decisions, that deserves attention.
Because when something goes wrong, you don't want responsibility moving between the factory, an external designer and a subcontractor.
You want to know:
Who is accountable for the result?
Engineering responsibility should be traceable, not assumed.
3. What Is Actually In-House — and What Is Outsourced?
Very few manufacturers make every component and perform every process themselves.
That is normal.
A supplier may outsource:
Machining
Surface treatment
Casting
Electrical components
PLC programming
Special fabrication
Certain testing procedures
Outsourcing itself is not the problem.
A well-managed supplier network can be perfectly capable of supporting a complex industrial project.
The real question is:
**What does the supplier control,
