The complete UK guide to checking that your manufacturer is real, legitimate, and capable — before you wire a penny.
Let's have a frank chat about something most sourcing guides skip over: the bit where you lose £15,000 to a factory that doesn't exist.
Every month, UK businesses — from scrappy one-person startups to established SMEs with seven-figure turnover — transfer large sums to Chinese or Vietnamese suppliers they've never verified. Some of those factories are genuine. Some are run by middlemen pretending to be factories. And a meaningful few are outright fraudulent operations set up specifically to collect deposits and disappear.
This isn't rare. At Epic Sourcing, we've seen the aftermath dozens of times: a business owner who found a “manufacturer” on Alibaba, exchanged a few messages, received impressive-looking sample photos, and wired a 30% deposit — only to discover the company doesn't exist at the registered address, the registration number is invalid, and the WhatsApp number has gone silent. Recovering that money from abroad is expensive, slow, and often futile.
The good news is that supplier fraud is almost entirely preventable if you know what to verify and how to verify it. Factory audits, document checks, third-party verification, and on-the-ground inspections are not exotic — they're standard practice for any buyer who has been doing this for more than a year.
This guide is for UK business owners, brand founders, and procurement teams who are:
By the end, you'll understand exactly how to verify any supplier, what a factory audit involves, which UK compliance checks you need to complete, and when it makes sense to let a professional sourcing team do this work on your behalf.
Supplier verification is the process of independently confirming that a manufacturer or trading company is legally registered, physically operational, and capable of producing the product you need at the quality you require. A factory audit is a structured on-site inspection — carried out by your team, a hired third party, or a sourcing agent — that assesses a factory's production capacity, quality systems, working conditions, and compliance with UK product standards.
UK businesses imported approximately £71 billion worth of goods from China in the twelve months to March 2025. That figure has grown consistently for over a decade, and it encompasses everything from consumer electronics and garments to industrial components and promotional merchandise. Vietnam is now the UK's fastest-growing sourcing destination, with bilateral trade reaching around £9.6 billion in 2024.
Most of that trade happens without incident. The factories are real, the products arrive, and the businesses grow. But the volume of trade also provides cover for a growing number of fraudulent operations, and the relative anonymity of international business-to-business dealing makes it easier for bad actors to operate — particularly when the buyer is in the UK and the supplier is 5,000 miles away in Guangdong or Ho Chi Minh City.
For a large corporation, losing £25,000 to a rogue supplier is embarrassing and annoying. For an SME working on tight margins, it can be existential. The average first order value for a UK SME importing from China ranges from £8,000 to £40,000. A 30–40% deposit on that order — which is typical for new supplier relationships — represents between £2,400 and £16,000 at risk before a single unit ships.
Add in the cost of the sample stage (often £500–£2,000 for shipping, modifications, and rework), the management time, and the opportunity cost of the delayed launch, and a failed supplier relationship can easily cost a business £20,000–£50,000 before any legal action is considered.
Beyond outright fraud, there's a more common and arguably more dangerous risk: a supplier who is real, who ships product on time, but whose goods don't meet UK safety standards. Under the UK General Product Safety Regulations 2005 (updated with the Product Safety and Metrology etc. (Amendment etc.) (EU Exit) Regulations 2019), it is the importer — that's you — who bears legal responsibility for ensuring that products placed on the UK market are safe. If an unsafe product injures a consumer, the Trading Standards authority investigates the business that imported and sold it, not the factory in Guangdong.
This is why supplier verification goes beyond checking whether a factory exists. It includes confirming that they have the technical capability, testing infrastructure, and quality systems to produce goods that meet UKCA marking requirements, UK electrical safety standards, or whatever other regulations apply to your product category.
A third-party factory audit typically costs between £350 and £900 for a standard one-day inspection. If it prevents even one failed order or one product recall, the return on that investment is extraordinary. UK businesses that build verification into their standard supplier onboarding process consistently report fewer quality failures and stronger supplier relationships over time.
Not every scam is dramatic. The most costly fraud targeting UK importers is often mundane: an operation that looks entirely professional until it isn't. Here's what we actually see in practice.
A ghost factory operates entirely online. It has a professional-looking Alibaba profile with verified status (which costs as little as $1,500 to obtain), a well-designed website, a WeChat or WhatsApp contact, and product photos sourced from real manufacturers. When you ask for samples, they either redirect you to a trading company that ships samples on their behalf, or they deliver samples that were produced by a real factory — which they have no intention of ever ordering from themselves.
The deposit gets paid. The production timeline passes with increasingly vague excuses. Then contact stops. The registered business address is a serviced office in Shenzhen that was vacated six months ago. Legal recovery through Chinese courts typically costs £15,000–£30,000 in legal fees and takes two to four years, with uncertain outcomes.
This is far more common than outright fraud, and it's not always malicious — but it creates real problems. A trading company represents multiple factories. They present themselves as a manufacturer because buyers prefer dealing directly with factories (lower prices, more control). The issue: you think you're dealing with the production team, but you're actually dealing with a middleman who adds 20–35% margin and has limited ability to resolve quality problems or implement your specific requirements.
When quality issues arise, the trading company blames the factory. The factory blames the trading company. You're stuck in the middle with 2,000 defective units arriving at Felixstowe, a retailer expecting delivery, and no clear route to resolution.
A supplier delivers excellent samples — genuinely well-made, correct specifications, proper materials. You approve the sample and place a bulk order. What arrives is made from cheaper materials, has corners cut on finishing, or uses a different production process that reduces cost but also reduces quality. This happens most often when the factory is under-resourced, when your order volume is too small to prioritise, or when the factory subcontracts to a lower-tier supplier without telling you.
In China, business registration information is publicly accessible through the National Enterprise Credit Information Publicity System (NECIPS). Fraudulent suppliers sometimes provide registration numbers that belong to legitimate businesses they have no affiliation with. When you look up the number and see a registered company, you assume everything is in order — but the company you're paying is not the company registered at that number.
| Scam Type | How Common | Average Loss (UK) | Prevention |
|---|---|---|---|
| Ghost Factory | Less common, very costly | £8,000 – £40,000 | On-site visit or third-party audit |
| Trading company posing as factory | Very common | Margin loss + quality risk | Business licence check + audit |
| Bait-and-switch quality | Common on first orders | £5,000 – £25,000 | Pre-shipment inspection |
| Registration number fraud | Less common | Full order value | Business verification service |
| Subcontracting without consent | Moderate | Quality + IP risk | Factory audit + contract clause |
Supplier verification is not a single check — it's a layered process. Each layer removes uncertainty and increases confidence. Here is the full process we use at Epic Sourcing when onboarding a new manufacturing partner for a UK client.
Every legitimate Chinese manufacturer has a Business Licence (繺纄æ…Ôæ‰, Yíngyè Zhízhào) issued by the State Administration for Market Regulation (SAMR). This document contains the company's legal name, registered address, unified social credit code (繱庒箇ç„Ïä&xB9;¢ç‚°é®¢ç棇), registered capital, and approved business scope. Request a copy as a standard part of your supplier qualification process — any legitimate factory will provide it without hesitation.
Once you have it, verify it at gsxt.gov.cn (National Enterprise Credit Information Publicity System). Enter the 18-digit unified social credit code and check that the name, address, and legal representative match what the supplier has told you. Also check the business scope: a factory registered only for trading should not be claiming to manufacture.
In Vietnam, the equivalent is the Enterprise Registration Certificate (Giáy chúng nhán ðăng ký doanh nghiêp) issued by the provincial Department of Planning and Investment. Verification can be done via the National Business Registration Portal (dangkykinhdoanh.gov.vn).
Alibaba's Gold Supplier badge means a company has paid for premium placement — it is not a quality or authenticity verification. However, Alibaba's on-site check (flagged as “Assessed Supplier” or “Verified Supplier”) does involve a physical visit by a third-party inspection company. Treat this as one data point, not a full endorsement.
More useful: check the supplier's transaction history and the proportion of repeat buyers. A factory with 85% repeat buyer rate and three years of verified trade data is significantly lower risk than one that appeared six months ago with glowing self-written descriptions and no transaction history.
Request a live video call and ask the representative to walk around the factory floor. You're looking for working machinery, workers at benches, finished goods in progress, and equipment that is consistent with the product they claim to make. A garment factory should have industrial sewing machines. An electronics factory should have PCB assembly equipment, soldering stations, and ESD protection infrastructure.
This is not foolproof — a fraudulent operation can walk through a borrowed factory space — but most straightforward scams collapse at this stage because they have nowhere credible to film. A legitimate factory will do this willingly and enthusiastically.
Depending on your product, ask for existing certification documentation: ISO 9001 (quality management), BSCI or SA8000 (social compliance), CE or UKCA test reports, RoHS compliance certificates for electronics, REACH declarations for chemicals or textiles. These don't replace a UK market compliance check — test reports issued to other buyers may not cover your specific product specification — but they demonstrate that the factory has at least gone through third-party assessment before.
Ask for two or three existing customer references — ideally UK or European buyers. Contact them directly (don't use contact details provided by the supplier; find the company and contact them independently). Ask specifically: Did products arrive on time? Were quality levels consistent? How did the factory handle problems? Would you reorder?
For any order above £10,000, commission a formal supplier verification report from a specialist provider. Services like Qima, Bureau Veritas, SGS, and Intertek all offer Chinese supplier due diligence reports that include company registration validation, legal status check, site confirmation, and basic financial health indicators. These typically cost £150–£400 and take three to five working days.
Epic Sourcing's own Chinese Company Verification service provides a comprehensive UK-focused report that includes business registration checks, manufacturing capability assessment, and an honest assessment of risk — compiled by our on-ground team in China with local language capability.
A factory audit is a structured on-site inspection. It goes significantly deeper than a video call or a document check — it involves a trained inspector physically visiting the factory, examining production lines, reviewing documentation, interviewing workers, and producing a detailed written report.
A social compliance audit assesses whether the factory meets minimum standards for worker welfare: wages, working hours, age of workers, freedom of association, health and safety, and living conditions for workers in dormitory housing. For UK brands selling to major retailers or supermarkets, this is often a non-negotiable requirement — M&S, John Lewis, and Tesco all require audit certification before they'll consider a supplier's products. Common frameworks include BSCI, SEDEX/SMETA, SA8000, and the ETI Base Code.
A QMS audit checks whether the factory has systematic processes for managing quality throughout production — incoming material inspection, in-process quality control, final inspection protocols, non-conformance reporting, and corrective action procedures. ISO 9001 certification is the benchmark, but an uncertified factory can have excellent quality systems. The audit determines the reality, not just the paperwork.
This is the audit you need when you're placing your first significant order. It assesses whether the factory actually has the machinery, workforce, and capacity to produce your specific product to your specification — and whether they have experience making something comparable. A furniture factory claiming it can produce injection-moulded plastic components is a red flag; a factory with five years of injection moulding experience and the right tooling is a very different proposition.
Most professional sourcing operations commission a combined qualification audit for new supplier relationships — covering legal status, production capability, quality systems, and basic social compliance in a single visit. This typically takes one day on-site and costs more than a single-focus audit, but it's far more efficient than conducting multiple separate inspections.
| Audit Type | Focus | Duration | Who Needs It |
|---|---|---|---|
| Social Compliance | Worker welfare, hours, wages | 1–2 days | Brands selling to UK retailers |
| QMS / ISO | Quality systems and processes | 1 day | Regulated or complex products |
| Production Capability | Machinery, workforce, capacity | Half–1 day | All new supplier relationships |
| Combined Qualification | Legal, capability, QMS, social | 1–2 days | First-time sourcing, high-value orders |
Factory verification tells you the factory is real and capable. UK compliance verification tells you the products it produces are legal to import and sell in Britain. These are two distinct processes and both are required.
Since January 2021, the UK has operated its own product conformity marking system: the UK Conformity Assessed (UKCA) mark. It replaces CE marking for most regulated products sold in Great Britain (England, Scotland, and Wales). Products that previously required CE marking — electrical equipment, toys, machinery, personal protective equipment, construction products, pressure vessels, and many others — now require UKCA marking to be sold legally on the GB market.
The UKCA mark must be placed on the product (not just the packaging) and requires a UK-based Declaration of Conformity with references to the specific UK statutory instruments that apply to your product category. Your factory in China or Vietnam cannot self-issue a UKCA declaration — it must be issued by the manufacturer, importer, or authorised representative based in Great Britain.
The UK government has extended the acceptance of CE marking in certain product categories, but these extensions have been modified and are product-specific. Do not assume CE marking is automatically acceptable for your product in 2026. Check the current UKCA guidance on gov.uk for your specific product category before placing any order — the rules vary significantly between categories and have changed multiple times since 2021.
Beyond UKCA, the General Product Safety Regulations 2005 impose a broad duty to ensure any product placed on the UK market is safe. Trading Standards can inspect, test, recall, and impose fines on importers. If your factory's products have failed safety tests for another market (this is checkable via the RAPEX/UK Product Safety Database), you need to know before you commit to that supplier.
To import goods commercially into the UK, you need an EORI number (Economic Operator Registration and Identification). This is free and takes around five minutes to register on the HMRC website. All import declarations for goods arriving at UK ports — Felixstowe, Southampton, London Gateway — are now processed through HMRC's Customs Declaration Service (CDS), which replaced the old CHIEF system. Ensure your freight forwarder is CDS-ready (most established ones are, but always confirm).
Confirm the correct commodity code for your product using the UK Trade Tariff tool. This determines your import duty rate, which typically ranges from 0% to 12% for most manufactured goods. Misclassification of commodity codes is one of the most common and costly errors UK importers make — it can result in underpayment of duty (leading to HMRC penalties) or overpayment (leading to unnecessary cost). If you're unsure of the correct code, a licensed customs broker can classify your product for a small fee and provide assurance in writing.
If you're sourcing from Vietnam, the UK-Vietnam Free Trade Agreement (UKVFTA) offers significant tariff advantages. Under UKVFTA, 65% of UK tariff lines on Vietnamese goods were eliminated immediately when the agreement entered force, rising to 99.2% over time. For certain clothing and textile categories, duties have fallen from 12% to 0%; for some electronics, from 3.5% to 0%.
To benefit from UKVFTA tariff rates, you must obtain a valid Certificate of Origin (Form EUR.1 or Invoice Declaration) from your Vietnamese supplier. The goods must genuinely originate in Vietnam under the rules of origin defined in the agreement — simply finishing or labelling goods in Vietnam from Chinese components may not qualify. Always verify origin eligibility with your customs broker before using UKVFTA rates.
| Check | Who's Responsible | UK Consequence if Missed |
|---|---|---|
| UKCA marking | Importer / authorised rep | Product recall, Trading Standards fine |
| General Product Safety | Importer | Criminal liability, product ban |
| EORI registration | Importer | Goods held at port |
| Correct commodity code | Importer / customs broker | HMRC duty assessment + penalties |
| UKVFTA origin cert (Vietnam) | Supplier + importer | Standard tariff rate applies, cost increase |
If your product contains chemical substances — dyes in textiles, coatings on furniture, additives in plastics — you may have obligations under UK REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals), which diverged from EU REACH post-Brexit. Your factory should be able to provide a Safety Data Sheet (SDS) for any chemical substances and confirm that restricted substances in your product are within UK REACH limits.
Experience teaches you to read signals quickly. Here are the warning signs that, in our experience, consistently precede either fraud or a badly failed order. If you see more than two of these, walk away.
Never pay a supplier using a platform transfer that bypasses the company's verified bank account (e.g., into a personal WeChat Pay account, a cryptocurrency wallet, or a “holding account” operated by an unnamed third party). Once that money leaves your account via these channels, it is almost certainly unrecoverable.
One of the most common objections we hear from UK SMEs is that factory audits are expensive and complex to arrange. The reality is considerably more straightforward than most people assume.
Going yourself makes sense if you're placing a large, strategic order and want to build a direct relationship with factory management. The cost of a flight, hotel, and three to four days in China or Vietnam (Guangzhou, Shenzhen, Hanoi, Ho Chi Minh City) typically runs to £1,500–£3,500. The limitation is that you need to know what to look for — many first-time factory visitors leave feeling impressed because factories put on a show.
Third-party inspection companies — Qima, Bureau Veritas, SGS, Intertek, TÜV Rheinland — operate locally in China and Vietnam with trained auditors who know exactly what to assess and how to document it.
Sourcing agents with local teams — like Epic Sourcing — conduct factory audits as part of their supplier onboarding process. The advantage is that the audit is interpreted through commercial context: not just “is this factory compliant?” but “is this factory suitable for this specific UK client's product and volume?”
| Audit / Check | Provider Type | Typical Cost (GBP) | Turnaround |
|---|---|---|---|
| Basic background check | Online verification service | £150 – £400 | 3–5 working days |
| Production capability audit | Third-party (Qima, SGS, etc.) | £350 – £650 | 5–10 working days |
| Social compliance audit (SMETA) | Accredited auditor | £600 – £1,200 | 7–14 working days |
| Combined qualification audit | Third-party or sourcing agent | £700 – £1,100 | 7–14 working days |
| UK buyer factory visit (DIY) | Self (flights + hotel) | £1,500 – £3,500 | You choose |
Arranging a factory audit typically takes one to two weeks from the point of instruction to the delivery of the written report. For UK buyers on a product launch timeline, budget this into your supplier selection process — if the audit raises concerns, you want time to find an alternative supplier without blowing your launch date.
Third-party audit reports typically assign an overall pass/conditional pass/fail result. A conditional pass means the factory meets basic standards but has identified non-conformances that require corrective action. Minor non-conformances (fire extinguisher servicing overdue, no English-language machine safety labels) can typically be resolved within 30–90 days and should be documented in a corrective action plan (CAP) that the factory commits to in writing. Major non-conformances indicate systematic problems or a factory that is not ready for your level of business.
An audit report gives you leverage in negotiations that a purely verbal relationship doesn't provide. If the report confirms the factory is excellent in quality systems but weak in social compliance documentation, you can negotiate audit improvement commitments into your supply agreement. Factories that want your business will generally commit to reasonable corrective actions when these are tied to the order.
A factory audit tells you the factory is suitable at the point of assessment. A pre-shipment inspection (PSI) tells you that your specific order has been produced to specification before it leaves the factory. A standard PSI using AQL sampling standards typically costs £200–£400 and should be conducted when 80–100% of production is complete.
If a product recall or Trading Standards investigation ever happens, your ability to demonstrate due diligence — including factory audits, compliance checks, and pre-shipment inspections — is your primary defence. Keep all audit reports, corrective action plans, and compliance certificates in a dedicated supplier file for each manufacturing partner.

Request the physical or digital copy of the supplier's Business Licence and note the 18-digit Unified Social Credit Code printed on it. Then search for that exact code on the Chinese National Enterprise Credit Information Publicity System at gsxt.gov.cn. The platform is in Chinese, but the company name, registered address, business scope, legal representative, and registration status will display. Cross-check these details against what the supplier has told you. If the name, address, and scope all match, it's a strong indicator of legitimacy. If anything doesn't match, or if the code returns no results, treat this as a serious concern and do not proceed without further independent verification.
No — not on its own. The Gold Supplier badge on Alibaba indicates that a company has paid for a premium membership tier, which provides enhanced listing features and some level of account review. The “Assessed Supplier” badge involves a physical visit by a third-party company, which is more meaningful, but it's a basic check conducted for the purposes of Alibaba's platform, not a comprehensive factory audit. These badges are a starting point for initial confidence — similar to checking that a UK business appears on Companies House — but they are not a substitute for an independent verification report or factory audit. Fraudulent operations have obtained Gold Supplier status and used it to scam buyers.
Remote auditing — using video calls and document submission — became more common during the pandemic and is now an accepted supplementary tool. However, it has significant limitations: factory management controls what the camera sees, documentation can be prepared specifically for the review, and many of the most important factory assessment signals are physical — noise levels, machine maintenance states, worker behaviour when unobserved. Remote auditing is better than no audit, but for any significant first order it should be followed by an in-person inspection, either by you or by a third-party company with local presence.
A factory audit happens before you place an order and assesses the factory's general capability, quality systems, legal status, and social compliance. It tells you whether this factory is suitable to work with. A pre-shipment inspection happens after your specific order has been produced — when 80–100% of production is complete — and assesses whether the finished goods match your specifications, are free of defects, and are properly packaged and labelled. Both serve different purposes and ideally you do both, but if you only have budget for one, prioritise the pre-shipment inspection to protect your specific order.
First, preserve all evidence — screenshots of conversations, payment receipts, emails, the supplier's Alibaba or website profile, and any contracts or purchase orders. Report the fraud to Action Fraud (actionfraud.police.uk) to create an official record. Contact your bank immediately — if payment was made via bank transfer recently, some banks can attempt a recall through their fraud team. If payment was made by credit card, a Section 75 claim may be possible for transactions over £100. For larger amounts, consult a solicitor with experience in cross-border commercial fraud. Going forward, consider using a letter of credit or escrow service for first orders rather than direct bank transfer.
Whether you need a quick supplier verification report or a full sourcing partnership with on-the-ground auditing in China or Vietnam, Epic Sourcing's UK team is ready to help. We've helped hundreds of UK businesses avoid scams, navigate compliance, and build reliable supplier relationships that actually last.
