Sample Brief
Most sourcing projects do not fail in production. They fail at the sample stage, quietly, and nobody notices until the container is already on the water.
The pattern is consistent. A buyer sends a design file, a reference photo, or a competitor’s product. The factory quotes a sample fee and a lead time. A sample arrives three weeks later. It looks broadly right. The buyer approves it, because it is close enough and the schedule is tight. Production starts. Six weeks later, the bulk order arrives and something is wrong — the fabric feels thinner, the colour is a shade off, the logo sits two millimetres lower, the zipper pull is a different shape.
None of those are factory errors, strictly speaking. They are gaps in the brief that the sample stage was supposed to close and did not.
Why Samples Get Approved Too Easily
Three forces push buyers into approving a sample they are not certain about.
The first is schedule. Sample rounds take two to four weeks each. If you need goods in March, an October conversation about a second sample round feels like a luxury you cannot afford. So you approve and hope.
The second is that a physical sample carries an authority a drawing does not. Once you are holding something, the temptation is to treat it as finished. It is not finished. It is a question the factory is asking you.
The third is that most buyers do not know which details are worth rejecting over. A two-millimetre logo shift sounds trivial. On a hard-surface product where the logo is the entire visual identity, it is the difference between a premium item and a cheap one.
The Five Things a Sample Brief Must Specify
A factory can only be accountable for what you told it. Before a sample is made, five categories need to be pinned down — in writing, not in a call.
Material and construction. Not “cotton” but the weight, the weave and the finish. Not “leather” but the type, the thickness and the backing. If you do not know the answer, that is fine — but say so, and ask for options rather than letting the factory choose silently.
Dimensions with tolerances. Every dimension that matters, with an acceptable range on each. “20 cm” is not a specification. “20 cm plus or minus 3 mm” is.
Colour, referenced to something physical. A Pantone number is a good start. A physical swatch is better. A photo on a phone screen is not a reference at all, because every screen renders colour differently and the factory will interpret it differently from you.
Branding method and placement. Print, embroidery, debossing, laser, heat transfer — each has a different visual result and a different minimum. Specify which, and specify position with a measurement from a defined edge, not “centred”.
Packaging and labelling. This is the most commonly skipped item and the one that causes the most expensive surprises, because it affects freight volume, customs documentation and retail readiness all at once.
Before the first sample is made, it is also worth stating explicitly what the product must not do — the failure modes you would reject over. Factories respond well to a short list of disqualifiers.
When One Sample Is Not Enough
Sometimes the material itself is the open question, and no amount of specification on paper resolves it.
A case from our own work illustrates this. A client wanted a belt bag and supplied a design concept, but had no material in mind. We sourced and sampled five different materials so the client could hold each one, compare hand-feel and structure, and choose with evidence rather than a photograph.
That is not inefficiency. Five material samples cost far less than one bulk order in the wrong material.
A reasonable rule: if the question is about appearance, one sample round is usually enough. If the question is about material performance, feel or durability, expect to need more than one — and budget the weeks for it at the start rather than discovering it in the middle.
Caps and other worn items behave the same way. Where fit and structure matter, we have run five to ten samples in a single round, because a cap that sits wrong on a head cannot be corrected by adjusting a drawing.
How to Read a Sample Quote
Sample fees vary enormously, and the variance is usually informative.
A very low or zero sample fee often means the factory intends to recover the cost in the bulk price, or that the sample will be a stock item pulled from existing production rather than something made to your specification. Ask which.
A high sample fee is not automatically a red flag. Custom tooling, new moulds, or a material the factory does not normally stock all cost real money. What matters is whether the factory can explain the breakdown.
Ask two questions before paying: is the sample fee credited against the bulk order, and is the sample made on the same production line as the bulk order. The second matters more than most buyers realise — a sample made by a technician in a sample room can be better than what the production line will deliver.
The Approval Itself
When the sample arrives, do not approve it in five minutes.
Put it next to the reference. Check it in daylight, not under office lighting. Measure the dimensions you specified. Compare the colour against the physical swatch, not against your memory. Test the moving parts — the zip, the clip, the hinge — repeatedly.
Then write down what you are approving. A short approval note stating the material, the colour reference, the dimensions and the branding method, signed off before production, is the single most useful document in the whole project. If a dispute arises later, it is the only thing that settles it.
And keep the approved sample. It is the reference for the pre-shipment inspection. An inspector comparing bulk goods against a signed, dated sample is doing a meaningful check. An inspector comparing against nothing is doing a visual once-over.
Where This Goes Wrong in Practice
Three patterns come up repeatedly.
The buyer approves a sample that was made with a material the factory had in stock, and production uses a substitute because the original was unavailable at volume. Prevention: specify that the approved material must be the production material, in writing.
The buyer approves a sample but never receives the specification back in written form, so the factory’s own understanding becomes the de facto standard. Prevention: the approval note.
The buyer approves a sample and then changes one detail — a colour, a logo size — by message, after approval. The change is applied inconsistently across production. Prevention: any change after approval restarts the documented specification.
What Good Looks Like
A well-run sample stage feels slower at the beginning and much faster at the end. The buyer spends an extra week writing a proper brief, waits for a sample that answers real questions, rejects one round rather than approving something uncertain, and then production runs without surprises.
The alternative — approve quickly, fix in production — almost never costs less. It costs in air freight, in rework, in markdowns, or in a batch of product you cannot sell.
If you are about to start a sampling round and are not certain what to specify, the useful conversation happens before the sample is made, not after it arrives.
