Whether the company you are buying from makes the product or buys it in is not always obvious from the website, and it is not always the most important question. It matters a lot in one specific situation and rather little in others – which is worth being clear about before spending time on it.
When it does not matter much
Standard items, bought in steady volume, with no technical questions. A trading company that consolidates several product lines into one container and one invoice is providing a real service, and for a mixed buy it is often the cheapest route even after their margin.
If nothing is going wrong and nothing needs changing, the distinction is not worth much of your time.
When it matters a great deal
When something goes wrong technically. A cracked flange, a panel that bows, a crate that fails in cold storage – these need someone who knows why, and a trading company is optimised for logistics, not for failure analysis. The route to an answer is long.
And when you need something changed. Changing a specification requires the maker.
Four signals
Do they answer technical questions directly, or relay them? A manufacturer answers in hours; a relay takes days and the answer comes back thinner.
Can they describe the process? Anyone who makes something can tell you how it is made, including what varies and what is difficult. It is a surprisingly reliable test.
What is the minimum quantity for a change? A manufacturer can quote a modified tool; a trading company has to ask someone, and frequently will not bother.
Who owns the tooling? Ask directly. A manufacturer will answer immediately because they know. A trading company often cannot.
The honest position
Both are legitimate and both are useful in different situations. What matters is knowing which you are dealing with so you can set your expectations – particularly your expectation of how quickly a technical question gets answered.

Why the website will not tell you
Both describe themselves as manufacturers, and in a loose sense both often are – a trading company may hold a minority stake in a factory, or have an exclusive arrangement, or simply describe itself generously. The label is not the test; the behaviour is.
The behaviour test, concretely
Send one technical question that a maker could answer and a reseller could not. Ask what happens to impact strength at a specific low temperature, or what the wall thickness is at the corner rather than at the centre.
A maker answers with a number, often with a caveat. A reseller asks the factory and comes back with something general, or does not come back. Time the response – the delay is the signal.
What to do with the answer, either way
If you are buying through a trading company and it works, keep buying through them. Consolidation, freight and paperwork are real services and worth the margin. Just know that when something goes wrong technically, you will need to escalate past them, and plan for that rather than discovering it.
What we can do
We manufacture PP crates for fruit and vegetables and will tell you plainly what we make and what we buy in. Ask us a technical question at quote stage – the answer time is the signal you are looking for.
