Sample development / Step 2

Sample development

Develop product samples in China with a clear brief, revision history and approval record. Confirm the reference, costs and checks for your first order.

For buyers preparing samples for a first order

A sample only settles an argument if everyone agrees what it is proving. Before we ask a factory to make one, we write down what has to be right: the reference item, the changes you want, and who signs off. Without an approval owner, a sample just starts another round.

Samples for brands and online retailers

You know what you want it to look like and roughly what it should cost. Turning that into something a factory can make is the gap.

Samples with several revisions

The colour, the feel, the packaging keep changing and nobody can remember which version everyone agreed on.

Approve a reference before ordering

You are about to pay a deposit and want the approved version pinned down first, with the quote tied to it.

Missing a reference or an approver

If there is no reference, no spec range, and nobody named to approve it, sampling just burns money. We say so before starting.

The same sourcing service has different risk controls for ecommerce, private-label, wholesale, and procurement buyers. Choose the buyer route before supplier search, samples, QC, and shipment work are scoped.

Ecommerce sellers

Check SKU margin, MOQ, samples, packaging, and replenishment risk.

Private-label brands

Control product development, sample approval, packaging, and production brief.

Wholesale buyers

Plan mixed SKUs, quote comparison, consolidation, and repeat supply.

Procurement teams

Review supplier evidence, risk notes, QC gates, and internal approval needs.

Record each version before approving the first order

Each version gets recorded against the brief, with the supplier's comment and any cost change it caused. You can see why version three costs more than version two. Samples ship by DHL, UPS, FedEx or SF — whichever is cheaper on that lane that week. You get the tracking number the day it leaves.

01Define the sample requirements and intended use

The reference, the changes, and the limits — written so three factories would read it the same way.

Sample requirements

02Select suppliers able to make the sample

Not every supplier will sample properly. Some quote fast and then hand it to someone else, which is where versions start drifting.

03Record revisions and changes to cost and timing

Each version is logged against the brief with what it did to cost and lead time.

04Confirm the approved version and production checks

Once a version is approved we hand it forward as the standard for the first order's QC.

Approved sample and QC requirements

Use the approved sample for quotes and production checks

The sample file names the approved version and the tolerance it was accepted at. It also states what the sample does not prove — packaging, regulatory testing, or anything the factory produced by hand that a production run will not repeat.

Sample requirements and agreed tolerances

The reference, the changes, and the tolerance — in one place, so every supplier is answering the same question.

Revision history, cost and timing

What each revision did to cost and lead time. This is the part buyers usually find out too late.

Approved reference and inspection criteria

The approved version, the retained sample, and the defect rules QC will inspect against.

Sample approval record

The reference item and the exact changes you want made to it.
Every version, what it cost, and what the supplier said about it.
Which version is approved, by whom, and at what tolerance — plus what the sample does not prove. One good sample is not production stability.

Questions about sample development

Is Aeonix a product design agency?

No. Industrial design, structural engineering and lab testing are other people's jobs. We take what you already have and make it something a supplier can act on.

Do I still need QC after sample approval?

Yes. An approved sample is a reference, not a guarantee of every production unit. The production process may differ from sampling, so check the order against the approved version and agreed inspection criteria.

When should sample and tooling fees be confirmed?

Before sampling starts. Ask specifically whether the fee is refundable, whether it comes off the order, and whether each revision costs again. The answers vary a lot between factories.

Send your reference and requested changes

Send the reference, the changes, and who signs off. We write the sampling brief, run the revisions, and record what each one changed in cost or lead time. Nothing is marked approved without a named owner.
