Right, let's be honest: if you're importing products from China or Vietnam, the single biggest variable in whether your business succeeds or gets burnt is who you have working on the ground for you. A good sourcing agent makes the difference between £699 of products landing at Felixstowe exactly as ordered — and £699 disappearing into a factory dispute that takes six months to resolve.
This guide is for UK business owners, Amazon sellers, brand builders, and retail buyers who are thinking about using a sourcing agent for the first time — or who've had a bad experience and want to understand what "good" actually looks like. We'll cover exactly what a sourcing agent does, how they're paid, how to spot the dodgy ones, and how to work with one in a way that genuinely protects your business.
At Epic Sourcing, we've helped hundreds of UK businesses source from China and Vietnam since 2017. We know this space better than most — and we'll give you the unvarnished version, not the sales pitch.
A sourcing agent is a person or company based in a manufacturing country — typically China, Vietnam, or India — who acts on your behalf to find suppliers, negotiate pricing, manage quality control, and coordinate shipments. Unlike a trading company (which buys and resells), a sourcing agent works exclusively for you, representing your interests against the factory.
The landscape for UK importers has changed significantly since 2020. Between Brexit reshaping customs procedures, the introduction of the Customs Declaration Service (CDS), evolving UKCA marking requirements, and a global supply chain that's had to reroute itself around US-China trade tensions — importing from Asia has become genuinely more complex than it was five years ago. A sourcing agent who understands both the manufacturing side and the UK import context is no longer a luxury; for most businesses ordering more than £20,000 of goods per year, they're a sensible investment.
The reality is that most UK business owners don't speak Mandarin or Vietnamese, don't have the time to fly to Guangdong to audit a factory, and don't know the difference between a legitimate factory and a trading company pretending to be one on Alibaba. A sourcing agent bridges that gap. They're physically present in the manufacturing ecosystem, they understand the cultural dynamics of negotiation, and — if they're doing their job properly — they're accountable to you, not to the factory. That last point is the critical one, and we'll come back to it several times throughout this guide.
UK businesses sourcing from China also benefit from the UK Global Tariff framework, which in many cases offers lower duty rates than EU importers face post-Brexit. And for businesses with Vietnam supply chains, the UK-Vietnam Free Trade Agreement (UKVFTA) offers meaningful duty savings — 65% of tariff lines eliminated immediately at ratification, rising to 99.2% over the implementation period. A sourcing agent familiar with HS code classification can help you claim those savings correctly.
When evaluating a sourcing agent, ask them: "What are the UKCA marking requirements for my product category?" If they give you a blank stare — or worse, start talking about CE marking as if it's still sufficient for the UK market — that's a sign they don't have specific UK import expertise. You want someone who understands that the UK and EU regulatory regimes diverged after December 2020.
This is where most guides get vague, so let's be specific. A good sourcing agent's job spans four distinct phases of your supply chain, and the quality of their work in each phase directly affects your margin, your timelines, and your product quality.
Your agent searches manufacturer databases, attends trade fairs (Canton Fair, China Import and Export Fair, Vietnam Manufacturing Expo), and leverages their existing factory network to find suppliers who match your product specification. The key word here is "specification" — a vague brief produces a vague shortlist. The better your initial brief, the better the suppliers your agent will surface. A good agent will shortlist three to five factories with comparable capabilities, not just the first one they can get on the phone.
This is where serious agents earn their fees. Verification involves checking the factory's business licence, confirming they actually manufacture the product (rather than acting as a middleman), reviewing their export history, and ideally conducting an in-person factory audit. For UK importers, this also means confirming the factory can comply with UK-specific requirements: UKCA marking, UK Conformity Assessed testing, REACH (UK REACH, not EU REACH), and any sector-specific regulations.
Once you've selected a factory, your agent manages the sample process — requesting pre-production samples, communicating your feedback, and iterating until the sample matches your specification. They then negotiate on price, MOQ, lead times, payment terms, and packaging. An experienced agent in China or Vietnam will often negotiate 10–20% better pricing than a UK buyer doing it directly, simply because they understand the cultural context and know which levers to pull.
During production, your agent serves as your eyes and ears on the factory floor. This ranges from informal progress check-ins to formal pre-shipment inspections (PSI), in-line inspections during production, or full AQL (Acceptable Quality Limit) inspections before goods leave the factory. For higher-value orders, this phase alone is worth every penny of the agent's fee — catching a defect before a container is loaded at Shanghai or Ho Chi Minh City is infinitely cheaper than trying to fix it after it arrives at Felixstowe.
Most sourcing agents will also coordinate with freight forwarders to manage the export side of logistics. This includes arranging the Commercial Invoice and Packing List (critical for UK customs), booking sea or air freight, confirming the Bill of Lading, and ensuring the goods are loaded correctly. Some agents have in-house logistics teams; others work with trusted freight partners. Either way, you'll still want your own UK-based customs broker or freight forwarder to handle the import declaration into the UK.
This is one of the most misunderstood distinctions in importing — and it has real financial consequences. Let's break it down clearly.
| Factor | Sourcing Agent | Trading Company | Direct Factory |
|---|---|---|---|
| Who they represent | You (the buyer) | Themselves | Themselves |
| How they make money | Service fee / commission | Margin on goods | Margin on goods |
| Price transparency | High — you see factory price | Low — margin hidden | High |
| Factory access | Full — multiple factories | Limited — own network | One factory only |
| QC independence | Independent of factory | Conflict of interest | Conflict of interest |
| MOQ flexibility | Can consolidate orders | Moderate | High MOQ typical |
| Best for | UK SMEs, brand builders | Commodity buyers, large volumes | Established, high-volume buyers |
| Typical markup/fee | 5–15% or flat service fee | 15–40% margin (hidden) | 0% (but you manage everything) |
Here's what most UK buyers don't realise: a significant proportion of "suppliers" on Alibaba, Made-in-China, and even Global Sources are trading companies, not factories. They present themselves as manufacturers but are actually middlemen who buy from the factory and sell to you at a markup. This isn't inherently dishonest — trading companies serve a legitimate purpose for buyers who want convenience — but if you're paying a trading company's margin on top of a sourcing agent's fee, you're paying twice for representation without realising it.
The fix is supplier verification. A sourcing agent should be able to confirm whether a supplier holds a manufacturing licence versus a trading licence via China's national enterprise database (GSXT). This is one of the first things Epic Sourcing checks on every supplier we present to a UK client.
Going direct to the factory is genuinely the right move in a few scenarios: you're ordering large volumes (consistently above £100,000 per order), you've built a multi-year relationship with the factory, you have staff who speak the language and can visit in person, and you have robust internal QC processes. For most UK SMEs — especially those still growing their brand — that's not where they are. Using a sourcing agent while you build that relationship and scale is the smarter path.
This is where things get murky, and where a lot of UK buyers get caught out. There are three main payment structures for sourcing agents, each with different implications for alignment of interests.
The most common model. The agent charges a percentage of the total order value — typically 5–15% — paid by the buyer. On the surface, this is fine. The problem arises when the agent is also receiving a "rebate" or "kickback" from the factory for directing business their way. This is widespread and rarely disclosed. An agent earning 8% from you and 5% from the factory has an obvious incentive to recommend the factory that pays the best rebate rather than the factory that makes the best product. Always ask explicitly: "Do you receive any payments, commissions, or rebates from suppliers?" A reputable agent will answer clearly.
Increasingly preferred by serious importers. You pay a fixed fee for a defined scope of work — supplier search, verification, sampling management, order placement. The agent's income is not tied to the order value, removing the incentive to inflate prices or recommend higher-margin suppliers. Epic Sourcing operates on a service fee model precisely because it aligns our interests with yours.
Some agents quote you an all-in FOB (Free on Board) price that includes their fee embedded in the goods price. This can work for commodity products where you're comparing like-for-like, but it makes cost transparency almost impossible. You genuinely can't tell whether you're getting a fair price. We'd recommend avoiding this structure unless you have a trusted long-term relationship and can independently benchmark the FOB price.
If a sourcing agent tells you their service is free, they are being paid by the factory — not by you. Their loyalty is to the factory, not to you. Free sourcing is almost always a factory sales channel dressed up as buyer representation. You'll typically pay 20–35% more for your goods than you would through a genuinely buyer-side agent, and your QC will be handled by people with a financial interest in your order passing inspection.
This is the section that most sourcing guides skip because it's complicated and not particularly glamorous. But for UK importers, getting compliance wrong can result in goods being held at the border, significant fines, or product recalls. Here's what you need to know.
Since January 2021, most products that previously required CE marking for the UK market now require UKCA (UK Conformity Assessed) marking instead. This covers a wide range of product categories including toys, electrical equipment, personal protective equipment, medical devices, and construction products. The UKCA marking requirements are broadly similar to CE but are administered separately — you cannot simply slap a UKCA mark on a CE-tested product without confirming the UK-specific conformity assessment route.
Your sourcing agent needs to understand this distinction. When briefing a factory on packaging and labelling, UKCA requirements must be clearly specified. Some factories — particularly those who primarily export to the EU — will default to CE marking unless instructed otherwise. Make sure your purchase order explicitly specifies UKCA compliance and the relevant UK legislation.
Every UK business importing goods must have an EORI (Economic Operators Registration and Identification) number. If you're VAT-registered, you likely already have one — it starts with "GB" followed by your VAT number. If you're not VAT-registered, you can apply for an EORI number separately via HMRC. Without it, your goods will not clear UK customs. This is basic housekeeping, but you'd be surprised how many first-time importers have a container arrive at Southampton before they realise they need one.
The UK phased out the old Customs Handling of Import and Export Freight (CHIEF) system and moved fully to the Customs Declaration Service (CDS) in 2023. If you're using a freight forwarder or customs broker to handle your import declarations — which you should be — they will already be operating on CDS. But you need to understand that import declarations now require more detailed commodity code information, and errors can result in delays or penalties. Your sourcing agent should be providing you with accurate product descriptions and HS codes to feed into your customs declarations.
The UK Global Tariff (UKGT) replaced the EU's Common External Tariff after Brexit. In many cases, UK rates are lower than EU rates — a deliberate policy choice to benefit UK importers and consumers. The rate you pay depends on the commodity code (HS code) of your product and its country of origin. For China, most manufactured goods face a standard duty rate. For Vietnam, the UKVFTA potentially reduces those rates to zero on qualifying products.
Do not rely on your sourcing agent alone for UK compliance advice. They operate in the export country and may not be fully across the latest HMRC or UKCA requirements. Always cross-check compliance requirements with your UK customs broker, a qualified trade adviser, or HMRC's official guidance. For regulated product categories (electrical goods, toys, PPE, food contact materials), consider independent UK-side testing and certification.
Post-Brexit, the UK runs its own REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regime, separate from EU REACH. If you're importing chemical products, plastic components, or goods that contain substances of very high concern (SVHCs), you need to ensure compliance with UK REACH, not just EU REACH. Your sourcing agent should be able to obtain Safety Data Sheets and substance declarations from the factory, but the regulatory compliance decision is ultimately yours as the UK importer of record.
| Compliance Area | Who Handles It | Key Resource |
|---|---|---|
| UKCA Marking | Importer (you) + factory | GOV.UK UKCA guidance |
| EORI Number | Importer (you) | HMRC EORI registration |
| Import Declaration (CDS) | Customs broker / freight forwarder | HMRC CDS guidance |
| Import Duty | Importer (you) — paid at border | UK Global Tariff / Trade Tariff tool |
| VAT on Import | Importer (you) — 20% | HMRC Import VAT guidance |
| UKVFTA preference claim | Importer (you) + factory (origin docs) | UKVFTA text, HMRC guidance |
| UK REACH compliance | Importer (you) + factory | HSE UK REACH portal |
Five years ago, this question rarely came up. China was the default answer for virtually every manufactured product category. Today, it's genuinely more nuanced — and the right answer depends on your product category, order volumes, and trade compliance objectives.
| Factor | China | Vietnam |
|---|---|---|
| Manufacturing breadth | Extremely broad — virtually every category | Strong in garments, footwear, furniture, electronics assembly |
| UK import duty | Standard UK Global Tariff rate | UKVFTA — potentially 0% on qualifying goods |
| MOQ | Varies widely; lower MOQs generally accessible | Slightly higher MOQs in some categories |
| Labour costs | Rising — particularly in coastal manufacturing hubs | Lower — competitive for labour-intensive products |
| Sea freight to UK | ~25–35 days (via Felixstowe or Southampton) | ~30–35 days (via Felixstowe or Southampton) |
| Sourcing agent availability | Abundant — large, mature ecosystem | Growing — fewer experienced agents available |
| US tariff exposure | High — relevant if you also sell into the US market | Lower — partially insulated from US-China tariffs |
The UK-Vietnam Free Trade Agreement came into force in January 2021 and offers UK businesses a genuine competitive advantage over EU buyers (who operate under their own EVFTA with different schedules). Under the UKVFTA, 65% of UK tariff lines on Vietnamese goods were eliminated immediately, with the remaining tariff reductions phased in over a 10-year schedule — reaching 99.2% elimination. For categories like textiles, garments, footwear, furniture, and certain electronics, the duty saving versus China-origin goods can be 12% or more of FOB value.
To claim UKVFTA preference, your goods must meet the rules of origin requirements — meaning a sufficient proportion of the product must be manufactured or substantially transformed in Vietnam. Your sourcing agent in Vietnam should be able to obtain a Certificate of Origin (Form EUR.1 or a Statement on Origin) from the factory to support your preference claim at UK customs. This is not complicated once you have a factory that understands the requirements, but it does need to be set up correctly from the start.
Vietnam is genuinely excellent for specific categories — garments, leather goods, wooden furniture, canvas bags, footwear, and increasingly electronics assembly. But if your product requires complex tooling, precision engineering, or you need a supplier with a deep technical supply chain (motors, electronics components, high-grade metals), China still has a significant structural advantage. The best sourcing strategy for most UK businesses is to evaluate both markets on merit for each product category, rather than adopting a blanket "move to Vietnam" policy.
There is no official registry of sourcing agents, no industry qualification, and no regulator. Anyone can set up a website and call themselves a sourcing agent. That's both the honest truth and the starting point for how you approach finding one.
The most reliable sourcing agents tend to come through personal referrals from other UK importers in your product category. If you're in an industry with a trade association, a Facebook group of FBA sellers, or a Shopify merchant community, those peer recommendations are worth a lot. Beyond personal referrals, sourcing agents with strong UK-market focus typically have a credible web presence targeted at UK buyers — they reference Felixstowe, they talk about UKCA, they price in pounds. That's a useful initial filter.
Trade fairs — particularly the Canton Fair in Guangzhou (April and October) and the China Sourcing Fair in Hong Kong — are still excellent venues to meet sourcing agents in person. Many agents attend specifically to build relationships with international buyers. Meeting someone face-to-face and walking the fair floor together tells you an enormous amount about whether they actually know the factories they claim to represent.
Before committing to any sourcing agent, work through this checklist:
Over the years, the Epic Sourcing team has seen pretty much every version of how things go wrong. Here are the patterns that should make you pause:
If your agent won't show you the factory's ex-works price and only quotes you a single "all-in" price, they're hiding their margin. Transparency is the baseline for a trustworthy relationship.
"The factory is very experienced, we don't need samples for this order." This is a flag. Samples are not optional — they're the only point in the process where you can catch specification errors before production begins.
A sourcing agent who is not physically present in the manufacturing country — or who doesn't have a full-time team on the ground — cannot do proper supplier visits, factory audits, or in-production inspections. They're reselling information they get from someone else.
If you send a brief today and receive a list of five "verified" factories tomorrow, those factories were not verified — they came from a database or a search engine. Proper supplier verification takes days, not hours.
If your sourcing agent won't provide a written service agreement setting out the scope, fees, timelines, and what happens in disputes — run. Verbal agreements are worthless when things go wrong, and sometimes things go wrong.
No reputable sourcing agent guarantees a specific price point before they've talked to the factory, or guarantees quality before they've seen a sample. Promises that sound too good are a sales technique, not a service standard.

For UK businesses building their own brand. We source, customise, brand, and deliver your own-label product — managing the full product development process from brief to shipment. Includes pre-shipment quality inspection.
Our premium end-to-end sourcing service for established UK brands. Full factory relationship management, multi-order QC, logistics coordination, and ongoing supplier monitoring. We become your permanent sourcing team without the overhead of in-house staff.
Already found a supplier but want to verify they're legitimate before sending any money? Our supplier verification service checks business licences, factory capabilities, production history, and export credentials — giving you the peace of mind to proceed with confidence.
All Epic Sourcing services are carried out by our team in China and Vietnam — not outsourced to third parties. We cover manufacturing hubs including Guangdong, Zhejiang, Fujian, Jiangsu, and Shandong in China, and Ho Chi Minh City, Hanoi, and the northern industrial zones in Vietnam. Every shipment we manage is coordinated for arrival into the UK — typically Felixstowe, London Gateway, or Southampton depending on your freight forwarder's routing.
Sourcing agent fees vary depending on the model and scope. Commission-based agents typically charge 5–15% of the total order value. Flat-fee service models — like Epic Sourcing — charge a fixed amount for a defined scope of work, starting from £699 for initial sourcing through to £3,299 for ongoing managed sourcing. In most cases, a good sourcing agent pays for itself through better pricing negotiation, quality control, and avoiding costly errors — particularly on your first few import orders. The hidden cost of not using a sourcing agent is often a failed first order, which can easily run to five figures.
Yes — and in some ways, first-time importers benefit most from sourcing agents because they have the least experience to catch errors independently. The key is matching the scope of the service to your order size. If you're placing a £3,000 trial order, you don't need the full premium service; you need a reliable supplier search, sample management, and a basic pre-shipment check. Epic Sourcing's White Label Package at £699 is designed specifically for this scenario — it gives you professional sourcing support without committing to a large ongoing retainer before you've tested the product and the market.
The most reliable signal is fee transparency. An agent who is paid a disclosed service fee by you — and who is not receiving undisclosed commissions from factories — has no financial incentive to recommend one factory over another. Always ask directly: "Do you receive any payments, rebates, or benefits from the factories you recommend?" A reputable agent will answer clearly and in writing. You can also look for structural signals: does the agent show you the factory's ex-works price, or only quote you an all-in price? Do they conduct quality inspections themselves, or do they rely on the factory's own QC reports? Independent QC is the operational equivalent of fee transparency — it removes the conflict of interest at the point where goods could be accepted or rejected.
A sourcing agent works on the production side of the supply chain: finding suppliers, managing sampling, negotiating prices, placing orders, and conducting quality control. A freight forwarder works on the logistics side: booking sea or air freight, managing the Bill of Lading, handling export customs in the origin country, and coordinating with UK customs agents for import clearance. Some sourcing agents have in-house freight teams or preferred freight partners, and some freight forwarders offer basic supplier introductions — but they are fundamentally different services. Most UK importers need both: a sourcing agent to manage the factory relationship, and a freight forwarder to manage the physical movement of goods to a UK port like Felixstowe or Southampton.
Alibaba is a directory of suppliers — it is not a verification service, a quality assurance programme, or a dispute resolution mechanism. Alibaba's "Trade Assurance" scheme provides some protection on payment, but it does not verify whether a supplier is a legitimate manufacturer, guarantee that samples match production, or protect you from quality deviations after the goods are shipped. Using a sourcing agent to verify and manage Alibaba suppliers is, in many ways, the most common use case for the service — particularly for UK businesses placing their first orders. Your agent visits the factory, confirms they're genuine, manages the sample process, and conducts the pre-shipment inspection that Alibaba's platform cannot provide.
You've done the research. Now it's time to work with a team that's already done this hundreds of times for UK businesses just like yours.
Whether you're sourcing your first product or scaling an existing supply chain, Epic Sourcing gives you a buyer-side team on the ground in China and Vietnam — without the cost of in-house staff.
