A free sample is never free. Someone pays for the material, the setup, the courier and the time, and knowing which one your supplier is absorbing tells you what kind of relationship you are starting.
The four costs inside a sample
Material, setup, labour and freight. On a custom colour, the setup usually exceeds the material. On a stock item, the material dominates. Courier is almost always the smallest line and the one buyers argue about most.
When a supplier offers a free custom sample, they are underwriting the setup. That is a real investment and it usually comes with an expectation of volume. It is fair, but it should be stated.

Why some suppliers charge and others do not
A factory with in-house sampling can absorb the cost more easily than a trader who buys samples from a third party. A charge is not a red flag; an unexplained free sample from a trader often means the sample is not from the production line.
The useful question is not ‘is it free’ but ‘is this sample from the line that will make my order’.
The sample that costs you the order
A development sample that outperforms production is the most expensive sample a buyer can receive. It passes every test, the order is placed, and the first lot fails.
Ask for the sample to be drawn from a production run, with the lot number on the label. If the product is new, ask for a pre-production sample and treat the first lot as a separate approval.

A sample policy that works
Pay the courier, ask for the sample to be production material, keep one sealed unit as the retained standard, and record the date and lot. That combination costs very little and prevents most of the disputes that follow.
On approval, ask whether the sample charge is credited against the first order. Most factories will agree, and the ones that will not are telling you something about how they handle small amounts.
The sample request that gets a useful answer
Ask for three things in one message: a sample in the exact construction you intend to order, drawn from a production run with the lot number on the label, and the test report for that lot. A supplier who can send all three is a supplier with a production line and a quality function.
If the construction does not exist yet, ask for a development sample and label the first production lot as a separate approval. That is the honest route, and it prevents the most expensive mistake in sampling: treating a development sample as evidence of production performance.

Budgeting for samples
Allow for the sample cost, the courier, and the time. The courier is usually the smallest line and the one that gets negotiated hardest, which is a poor use of attention. The time is the line that matters: two rounds of sampling at ten days each is three weeks of the calendar, and that is the number to put in the launch plan.
Courier, customs and the paperwork nobody mentions
A sample shipment is an export like any other. It needs a commercial invoice, a declared value and, for some destinations, a certificate. Declaring a sample as a gift to avoid duty is common and it is also the reason samples get held, which costs more time than the duty would have.
Declare the material value honestly, use the supplier’s courier account where possible, and ask for the tracking number the same day. A sample that arrives three weeks late has already cost you the decision window.
What to do when the sample is right and the first lot is not
Compare the two against the retained standard, then check the lot number and the production date. If the sample was development material, the difference is expected and the fault is in the approval process. If the sample was production material, the fault is in the supplier’s process control, and that is a different conversation with a different remedy.
| Cost line | Who usually pays | What to check |
|---|---|---|
| Material and setup | Supplier, on a stock item | Whether the sample is production material |
| Custom colour setup | Buyer, or credited against the order | Whether the credit is written down |
| Labour | Supplier | Whether the sample came from the line |
| Courier | Buyer | Declared value and paperwork |
| Your time | Buyer | Two rounds of sampling is three weeks |

Questions buyers ask before ordering
Can you quote against a specification I write myself?
Yes. Send it as written and we will come back with a line-by-line response, including where we would deviate and why. That is more useful than a price against a document we have silently reinterpreted.
What do you need to start?
End use, quantity per colour, destination market and the date you need the goods. With those four we can quote; without them we are guessing.
Three questions, and the answers that separate mills
If the sourcing decision in front of you is going to be decided on a call, take these three questions into it.
| Question | Answer that should worry you | Answer that holds up |
|---|---|---|
| Which test catches compression set? | “We have never had a complaint.” | Pilling — on the production lot, with the acceptance figure written into the report and not into the email. |
| May I see a report for a lot you shipped last month? | “That is confidential customer information.” | A redacted report, which carries every number that matters and none of the customer’s identity. |
| Where in the 3-15 mm band will this order sit? | “In the middle, normally.” | A stated target and the readings behind it. Thickness drifting inside the band is how a conforming lot still fails. |
Failure modes, and the test that catches each one
A specification only earns its keep if it names the failure it prevents. These are the two that matter for the sourcing decision in front of you.
| Failure | What triggers it | Test to demand on the production lot |
|---|---|---|
| Delamination | Flame lamination is cheap and fails at the adhesive line under heat and solvent. | Colour fastness to rubbing — ISO 105-X12; acceptance >= grade 4 dry, >= 3-4 wet |
| Snagging and pilling | Long float yarns on the face; loose stitch density. | Dimensional change — ISO 6330 / ISO 5077; acceptance <= 3 % |
The other two, with acceptance numbers attached, are in the full failure analysis for 3D mesh. A supplier who cannot name the mode he sees most often is describing a catalogue, not a process.
The same question, asked of PVC slats
The two lines fail differently, so the wording that protects you differs too. On PVC slats the recurring modes are these, caught with a different test.
| Failure | What triggers it | Test to demand on the production lot |
|---|---|---|
| PVC slats: Yellowing | Insufficient or wrong UV stabiliser; often TiO2 grade rather than a true UV package. | Impact at low temperature — -10 C drop test; acceptance no crack |
| PVC slats: Heat warping | Heat deflection temperature below the in-window temperature. | Colour fastness to light — ISO 105-B02; acceptance >= grade 4 |
Want a line-by-line response to your RFQ?
Send the end use, the quantity and the destination market, and we will come back with a specification that meets it, a price at your volume and the test reports that back it up. Samples are free for qualified programmes; we charge the courier only.
