Product Samples from China: Types, Costs and How to Evaluate Them

A sample is the cheapest place to find a problem. Once a factory has bought materials and started a production run, every correction costs more and takes longer. This guide covers the sample types you will be offered, what they typically cost and who pays, how to get sample fees back, how to ship samples, and how to use a golden sample to hold the factory to what you approved.

The four sample types#

Each sample type answers a different question, so you usually need more than one. Here is how they differ:

A stock sample does not prove the factory can make your version. A custom sample made by hand in a sample room does not prove the production line will match it. That is why the pre-production sample matters: it should be made with the same fabric lot, the same mould and the same printing method as your order.

What samples cost and who pays#

In most cases the buyer pays. For stock items, suppliers often charge the unit price or a modest fee, and sometimes waive it for cheap items. Custom samples cost more because the factory has to source materials, make printing plates or screens, and spend technician time on a single piece. Alibaba.com's own seller guidance, as of 2026, describes paid samples as standard practice in B2B trade and cites fees of roughly $50–150 for many products, before shipping. Products that need new tooling are a different case: the mould is paid separately, and the first samples come off that tool.

What you can negotiate is who carries the cost in the end. Common arrangements:

• Sample fee credited against the bulk order. The supplier deducts the sample fee from your first production invoice if you order within a set period or above a set quantity.
• Buyer pays shipping only. Common for low-value stock samples.
• Partial credit. Some suppliers refund part of the fee, or only once your order reaches the MOQ.

Agree the refund terms in writing before you pay, including the order size and time window that trigger them. If you place the sample order through Alibaba.com, paying via the platform brings it under Trade Assurance, which covers orders that are not shipped or arrive not as described, provided the payment went through Alibaba.com.

Shipping samples by express courier#

Samples almost always travel by international express courier because they are small and time-sensitive. Couriers charge by the higher of actual weight and volumetric weight, so bulky, light items such as pillows or packaging cost more than their weight suggests. Two ways to pay:

1. Supplier's courier account: simple, but the cost is added to your sample invoice with a markup you cannot see.
2. Your own courier account: you give the supplier your account number and pay the carrier directly, usually at better rates, and you control tracking.

Samples are still imports. They need an invoice with an accurate description and value, and duties may be due. If you import into the United States, note that CBP has suspended duty-free de minimis treatment for shipments valued at $800 or less; the underlying executive order took effect on August 29, 2025, and CBP made the suspension indefinite in rules announced on June 24, 2026. As of September 2026, budget for duties and entry fees on US-bound samples. Do not ask the supplier to under-declare value — it can cause delays and penalties. Once you move to bulk orders, see sea vs air vs rail vs express for choosing the right mode.

How to evaluate a sample#

Judge a sample against a written specification, not a feeling. Before samples arrive, write down what "correct" means, then check each point:

1. Dimensions and weight — measure against your spec sheet and record the figures.
2. Materials — check composition labels, thickness, gauge, fabric weight or plastic type. Ask for material test reports where they matter.
3. Colour — compare against a Pantone reference or a physical colour standard in daylight, not only on screen.
4. Function — use the product as a customer would, including repeated opening, closing, charging, washing or loading.
5. Workmanship — seams, edges, burrs, glue marks, print alignment and finishing.
6. Branding and packaging — logo size and position, labels, barcode scannability and carton markings.
7. Safety and compliance — sharp edges, small parts, required warning labels and whether the product can pass the testing your market requires.
8. Consistency — if you ordered more than one piece, compare them with each other.

Write your findings as numbered comments with photos, and send them back to the supplier in one message. A sample that needs changes means another round; do not approve it "with comments" unless the changes are minor and clearly written into the purchase order.

Keep a sealed golden sample#

The golden sample turns your approval into something enforceable. Once the pre-production sample is right, have at least two identical pieces signed and dated by you and the supplier, sealed with tamper-evident tape or stickers, and labelled with the order number.

• One set stays at the factory as the production reference for the line.
• One set stays with you, or with your agent in China, for disputes.
• Your inspector needs a reference too, either a third set or detailed photos and measurements.

At inspection, the golden sample defines what a defect is. Combined with an agreed sampling plan such as those in ISO 2859-1 (see AQL explained), it gives you objective grounds to accept or reject a lot. Our pre-shipment inspection checklist shows how inspectors use it.

If the factory changes a material, component or supplier after approval, a new pre-production sample and a new golden sample should be made. Put that rule in your purchase order.
