Never skip the sample stage. Here's exactly how UK importers request, evaluate, and approve product samples from Chinese factories — and the four Sourcing Hacks that make the difference.
In summary: Getting product samples from Chinese manufacturers involves identifying the right factory, requesting samples formally, paying a sample fee (typically £15–£100 per sample), evaluating quality against your specifications, and requesting revisions before placing a production order. Expect the process to take 2–6 weeks. Never skip sampling — it's the single most important step before committing to a bulk order.
I've seen it happen more times than I care to admit. A UK entrepreneur, buzzing with excitement about their new product idea, finds a supplier on Alibaba, sees the photos, reads the glowing product description, and — against every instinct they probably had — places a bulk order without requesting a sample first.
Six weeks later, a box of protein shakers arrives that look nothing like the photos. The lids leak. The printing is off. The plastic smells questionable. This is a story as old as international trade itself. And it's almost entirely preventable with a robust sampling process.
Whether you're considering our White Label Package, building a Private Label product, or sourcing direct from Chinese factories, the sample stage is non-negotiable.
The sampling process follows a fairly consistent pattern regardless of product category. Here's how it typically unfolds for UK importers.
Step 1 — Find and shortlist factories. Before you can request samples, you need at least 2–3 factories to compare. Our guide on how to find reliable manufacturers in China covers this in depth.
Step 2 — Send a formal sample request. Contact each factory with a clear brief: product specifications, dimensions, materials, colours, quantities, and any UK regulatory requirements.
Step 3 — Pay the sample fee. Most factories charge for samples. This is normal and healthy — it filters out time-wasters and confirms you're a serious buyer.
Step 4 — Receive and evaluate. When samples arrive, evaluate them methodically against your spec sheet. Don't just eyeball them — measure, test, and document.
Step 5 — Request revisions or approve. If the sample isn't right, communicate specific, numbered revision requests. A good factory will make two to three revision rounds before charging again.
Sourcing Hack #1:
Always request samples from at least 3 factories simultaneously. This isn't just about finding the best quality — it gives you commercial leverage. When you can truthfully say "we're comparing several suppliers," factories are more motivated to put their best work forward and offer competitive pricing.
Sample costs vary by product complexity and factory, but here are typical ranges for UK importers:
Simple products (phone cases, tote bags, basic accessories): £10–30 per sample, including express courier.
Mid-complexity products (water bottles, gym accessories, kitchenware): £25–80 per sample.
Complex products (electronics, machinery, custom moulded items): £80–500+ per sample, depending on whether new tooling is required.
Always clarify: does the sample fee include DHL or FedEx shipping to your UK address? Many factories quote the sample price without freight. Also ask whether the sample fee is refundable against your first production order — many factories will credit it back once you hit a minimum order quantity. This is worth negotiating from the outset.
Sourcing Hack #2:
If a factory says "samples are free, just pay shipping" for a complex product, be cautious. Free samples for anything beyond a basic catalogue item usually means you're getting a stock item pulled from their warehouse — not a sample made to your specifications. The sample fee is what ensures the factory actually invests time in making what you asked for.
For existing catalogue products (ODM / white label), expect 7–14 days for the sample to be prepared, plus 3–5 days express shipping to the UK via DHL or FedEx.
For custom products requiring new components, colour matching, or original tooling, allow 3–6 weeks for sample preparation before shipping.
If a factory quotes you "2–3 days" for a complex custom sample, they're either sending you an existing product rather than your spec, or they're not being straightforward with you. Either way, it's a red flag worth noting.
During the wait, use the time productively. Review our complete guide to importing from China to the UK to understand the logistics steps that come after sampling is approved.
Sourcing Hack #3:
Build a sample evaluation scorecard before the samples arrive. List every specification you care about — dimensions, weight, material, finish, function, packaging — and score each sample against it numerically. This removes emotion from the decision, makes revision requests clearer, and gives you documentation if you later need to prove the factory supplied something different from what was approved.
When your samples land on your desk, resist the urge to just look at them. A proper evaluation should cover the following.
Physical dimensions. Measure everything against your spec sheet with actual measuring tools — calipers and tape measures. Not eye-measuring. Discrepancies of even 2–3mm can affect packaging, stacking, and usability.
Material and finish. Does the material match what was specified? Does the surface finish look and feel right? If you specified matte PP plastic and the sample has a shiny finish, that needs to go back with a correction note.
Functional testing. Use the product the way your customers will. Fill the water bottle. Open and close the lid 50 times. Drop the item from waist height. What breaks in your hands breaks in your customer's hands.
Branding and printing quality. Check logos, colours, and text against your design files. Pantone colour matching is notoriously difficult across factories — if colour accuracy matters to your brand, specify Pantone codes explicitly in your brief.
Packaging. If you've specified custom packaging, evaluate this too. Our post on safety checks before your first purchase covers broader due diligence worth reading alongside this guide.
This is where clear communication becomes absolutely critical. Chinese factory engineers are highly skilled but can only fix what they understand needs fixing. Vague feedback — "it doesn't look right" or "the quality isn't good" — produces vague results.
Write numbered revision requests. Be specific. Include photos with annotations where possible. For example: "Revision 1: The lid diameter measures 68mm. It should be 72mm per the attached spec sheet. Please correct and confirm before producing the revised sample."
Clear, numbered, documented. That's the standard. It also protects you — if there's a dispute later about what was approved, you have a written record.
Sourcing Hack #4:
Create a "golden sample" — one approved sample that you sign, date, and store safely. Send the factory a photo of the signed golden sample. This becomes the quality reference standard for your production order. If production deviates from the golden sample, you have documented evidence of what was agreed. It's a simple step that prevents enormous headaches down the line.
Yes — and earlier than most people realise. UK import regulations, HMRC requirements, and product safety standards should inform your sample brief from the very beginning.
If you're importing electrical products, they need to meet UK Electrical Safety Regulations. Food-contact products must comply with UK food contact materials legislation. Toys must meet UK Toy Safety Regulations. The CE mark has largely been replaced by the UKCA mark for Great Britain. These compliance requirements affect materials, manufacturing processes, and testing protocols — all of which need to be built into your sample spec, not bolted on after the fact.
Working with a sourcing agent who understands UK compliance is one of the smartest moves UK importers can make. That's exactly what we do at Epic Sourcing. You can learn more about our approach to working with a China sourcing agent.
If you're sampling with a factory you found yourself on Alibaba, you're operating on trust, language, and hope. If you're working through a sourcing agent with a verified factory relationship, you're operating on documentation, accountability, and leverage.
A sourcing agent who has an existing relationship with a factory can push for faster sample turnarounds, clearer revision communication, and honest feedback on whether your spec is manufacturable. They can also visit the factory in person to conduct a quality check on your samples — something no amount of photos can replicate.
Our White Label, Private Label, and Secret Label packages all include managed sampling as a core part of the service. Once you've mastered sampling, the next decision is whether to go OEM or ODM for your production run — our guide breaks down exactly how to choose.
We also cover how to source directly and reduce costs in our post on how small businesses cut costs by sourcing directly.
Contact the factory with a detailed brief including product specifications, dimensions, materials, colours, and intended use. Confirm the sample price, shipping method to the UK, and lead time. Pay the sample fee and provide your UK delivery address. Follow up if you haven't received tracking details within 48 hours of the agreed dispatch date.
Sample costs range from £10–£500+ depending on product complexity. Simple catalogue products cost £10–30 including express shipping. Custom products with new components or tooling can cost significantly more. Always confirm whether the sample price includes DHL or FedEx shipping to the UK, and ask whether the fee is refundable against your first production order.
Factory preparation time is typically 1–2 weeks for existing designs and 3–6 weeks for custom products. Express air shipping (DHL, FedEx, UPS) from China to the UK takes 3–5 business days. Budget 2–8 weeks total from sample request to delivery, depending on product complexity and factory workload.
Send numbered, specific revision requests with photos and annotations explaining each issue. Most good factories expect 1–3 revision rounds before a sample is approved. Document everything in writing — email trails are your best protection if a dispute arises later. If after 3 revision rounds the quality is still not acceptable, it may be time to evaluate other factories.
You can source samples directly, but a sourcing agent adds significant value — especially for complex products, custom development, or first-time importers. An agent with factory relationships can negotiate faster turnarounds, conduct in-person quality checks, and manage communication in Chinese. For UK small businesses, the cost of a good sourcing agent is almost always lower than the cost of a bad sample batch making it to a production order. Contact Epic Sourcing to discuss how we can help.
A golden sample is the approved, signed sample that becomes the quality reference standard for your production run. Once you approve a sample, sign and date it physically or via a documented photo confirmation. Send the factory a photo of the signed sample. This creates a clear, legally useful baseline — if production deviates from the golden sample, you have documented evidence of what was agreed.
Getting sampling right is the foundation of everything that follows. A good sample process saves you money, protects your brand, and gives you confidence going into production. A skipped or rushed sampling process is where most sourcing disasters begin.
