How to request and evaluate samples from China

A sample is the single cheapest piece of insurance in importing. For the price of one unit and a courier fee, you learn things no amount of messaging will tell you: whether the supplier can actually make the thing, whether it survives real use, and what "good" looks like when the bulk arrives. Skipping the sample to save a few weeks is how buyers end up with a container of regret.

Here is how to request, pay for, and properly evaluate a sample before you commit.

Requesting the right kind of sample

There are two things you might be sent, and you should be clear which you want.

• A stock sample is something the supplier already makes. It tells you about general quality and finish, but not about your specific order.
• A custom or pre-production sample is made to your exact specification, colour, logo and packaging. It is slower and costs more, but it is the only true preview of your order.

For a first deal with a new supplier, a stock sample is usually enough to judge whether they are worth pursuing. Before you pay for tooling on a custom run, insist on a pre-production sample you have approved in writing.

There is a subtle risk with custom samples worth flagging early. A supplier eager to win your order may hand-make a perfect sample with extra care that the production line will never reproduce at scale. The sample is a promise of what they can do, not a guarantee of what they will do across a thousand units. That is exactly why the bulk run still needs checking, no matter how good the sample looked.

Who pays, and why you should

Expect to pay for the sample and the courier, and be glad to. A supplier who gives away samples freely is often a trading company treating it as a sales cost, while a serious factory charges because each sample disrupts the line.

A common and fair arrangement is that the supplier charges for the sample, then credits that cost back against your first bulk order. Ask for that. It signals you are a real buyer and keeps the supplier honest about quality, since they know the bulk order is coming.

Never place a full order on photographs. A photo cannot be washed, dropped, plugged in or left in the sun. The sample is where you find out what you are actually buying.

Stress-test the sample, do not just admire it

This is the step most buyers skip. When the sample arrives, put it through what it will face in real use and in the Nigerian climate.

1. Use it the way your customer will. Wash the fabric several times. Charge and run the device. Load the bag. Run the motor under load.
2. Test for the local conditions. Heat, humidity, dust and unstable power are real. A product that fails in those conditions will come back to you.
3. Check the details that get cut on bulk runs. Stitching, welds, screw fit, paint finish and packaging are exactly where factories economise at scale.
4. Confirm measurements against the spec. Measure it yourself. Do not trust the listing.

Document everything

A sample is only useful as a reference if you can prove what you approved. Build a small record before you order the bulk.

• Photograph the sample from every angle, including labels, stitching and packaging, with something for scale.
• Write down the exact measurements, weight, colour reference and materials.
• Keep the physical sample, sealed and labelled with the date and supplier.
• Get the supplier to confirm in writing that the bulk will match this approved sample.

That record is what turns a vague complaint into an enforceable one if the bulk run drifts. It also feeds directly into your inspection brief. When you cannot fly out, a pre-shipment inspection checks the bulk against the very sample you documented, and AQL sampling sets how many units get pulled and checked.

Compare more than one supplier

Where the budget allows, order the same sample from two or three suppliers at once. Holding three versions of the same product side by side teaches you more in an afternoon than weeks of messaging. You see which factory finishes its edges properly, which one cut a corner on the fastenings, and which one simply understood your brief. It also gives you a real fallback if your first choice falters, rather than starting the whole search again under time pressure.

This small spend slots neatly into your wider vetting. The supplier who sends the best sample, answers questions clearly and shows a clean profile, as covered in reading an Alibaba supplier profile, is usually the one worth the bulk order.

A quick sampling checklist

1. Decide whether you need a stock or pre-production sample.
2. Agree the sample cost and whether it credits against the bulk order.
3. Pay for the sample and courier promptly to signal you are serious.
4. Stress-test it against real use and local conditions.
5. Photograph, measure and seal it, and get written confirmation the bulk will match.

Paying for samples is also a small, low-risk way to test how settlement feels with a new supplier. You can make a request to pay the sample cost in RMB on Alipay from Naira, then use the same routine for the bulk order once the sample passes.
