Factory or Trading Company for a Charger Programme?

Factory versus trading company for a charger programme: what each brings, where each fails, how pricing differs and how to tell which one you are talking to.

Factory or Trading Company for a Charger Programme?
October 11, 2026 · TKMAN · 7 min read

A brand paid a trading company’s margin and still dealt with the factory’s quality problem. The supplier had been honest about its role; the brand had assumed that the relationship came with process control, and the assumption survived until the first batch with a drifting limit. The two models are both legitimate, and they solve different problems.

Factory or trading company: what actually differs

The difference is who owns the line, the design and the records — not who answers the email.

A factory controls the process, the fixtures and the test limits, and it holds the platform and the certification file for its own design. A trading company controls the relationship, the range and often the packaging and assembly, while the production platform belongs to someone else. Most of the practical consequences follow from that one sentence.

Neither model is better in the abstract. A programme that needs a certified platform with documented limits is served by the owner of the line; a programme that needs three product categories, mixed packaging and one invoice may be served better by a trading company with the right factory relationships.

What a factory brings: process control and the line

Auditable process, owned tooling and a direct answer on capacity.

The line, the fixture, the test limits and the component lots are all inside the same organisation, which is what makes an audit meaningful and a corrective action enforceable. The platform revision and the certification file are the factory’s own assets, so a question about a revision is answered rather than relayed. The limits of the model are range and flexibility: a factory builds what it builds, and a brief outside its platforms becomes a development project.

What a trading company brings: range and commercial flexibility

Access to several factories, consolidated packaging and one commercial interface.

A trading company can source a range across categories, handle assembly, kitting and packaging in its own facility, and consolidate documentation and shipping into a single relationship. For a channel that sells bundles or gift programmes, that flexibility is the product. The exposure is that process control sits one step away, and the step is only as good as the agreement behind it.

Where each one fails

Four failure modes, two for each model.

A factory with no platform fit forces a development project onto a brief that needed none, and a factory with full order books will move your delivery date without a production reason. A trading company that does not name its line leaves quality unauditable, and one that changes factories between orders changes the product without changing the specification.

How to tell which one you are talking to

Three questions, and the answers are difficult to improvise.

Which production site builds the product, and who owns the tool; who holds the platform revision and the test limits; and which company is named as the responsible party in the certification file. A factory answers all three about itself. A trading company answers with a partner’s name, and a good one has the arrangement in writing. A supplier that answers vaguely on all three is neither, which is the answer that matters most.

Dimension Factory Trading company What it decides
Process control Owned and auditable Depends on the partner How a defect is handled
Platform and limits Its own design Sourced How fast a revision question is answered
Range Narrow, deep Wide, shallow Bundles, kitting, categories
Pricing Cost plus margin Factory price plus margin Where the extra per cent sits
Certification file Held for its own revision Relayed from the factory What the brand can produce on request
Main risk No platform fit for the brief Unauditable process The shape of the first problem

Pricing: where the margin sits

The margin is not a fault; it is the price of what the relationship provides.

A trading company adds its margin to a factory price, which means the same platform can cost more through the trading route than directly. What that margin buys is range, consolidation, packaging work and a single interface for several categories, and it is worth paying where those are the requirements. It is not worth paying where the programme needs process control and a certified platform, because those are the items the model does not add.

Mixing the two without losing control

A trading relationship can serve a programme well if three things are written down.

The factory that produces each item, the party holding the platform revision and the test limits, and the party named in the certification file — each recorded in the supply agreement together with the process for a change of factory. With those three, the brand keeps the ability to audit, to trace and to answer a marketplace question, whichever model is on the invoice.

FAQ

Is a trading company less reliable than a factory?

Not inherently. The reliability depends on whether the line behind it is named and whether the agreement covers process control, corrective actions and a change of factory. Where those are written, the model can be as reliable as a direct relationship. The reliability depends on whether the line behind it is named and whether the agreement covers process control, corrective actions and a change of factory.

How do we find out whether a supplier is a factory?

Ask which production site builds the product and who owns the tool, which company holds the platform revision and the limits, and which company is named in the certification file. A factory answers about itself; a trading company names a partner. Ask which production site builds the product, who owns the tool, who holds the platform revision and the limits, and who is named in the file.

Does buying through a trading company cost more?

It normally adds a margin to the factory price, and it can also reduce cost by consolidating packaging, kitting and shipping. Whether it is more expensive overall depends on what the programme needs, which is why the comparison belongs after the scope is aligned. It normally adds a margin to the factory price and can also reduce cost by consolidating packaging, kitting and shipping, so the comparison belongs after the scope is aligned.

Can we move from a trading company to the factory later?

It is possible where the platform, the tooling and the certification arrangements allow it, and it is much easier when the factory was named from the beginning. Moving without that knowledge means starting the qualification again.
