Epic Guides · Manufacturing
Right, let's cut through the confusion. OEM and ODM are two of the most misused terms in the sourcing world — and getting them mixed up can cost you months of wasted time and thousands of pounds. This guide explains exactly what each model means, which one suits your business, and how to use them correctly when sourcing from China or Vietnam.
This guide is for UK business owners, brand founders, and product developers who are exploring manufacturing options in China or Vietnam. Whether you're launching your first product or scaling an existing range, the OEM vs ODM decision is one of the most important you'll make — and most people don't fully understand it before committing.
At Epic Sourcing, we've helped hundreds of UK businesses navigate exactly this decision. We've seen brands spend £15,000 tooling up for OEM when a £2,000 ODM option would have done the job perfectly. We've also seen the opposite — businesses that went ODM to save money and ended up with a product they couldn't differentiate in the market. This guide will help you avoid both mistakes.
OEM (Original Equipment Manufacturing) — The manufacturer produces a product to your specification. You own the design, the moulds, and the IP. The factory builds exactly what you tell them to build.
ODM (Original Design Manufacturing) — The manufacturer already has an existing product design. You choose from their catalogue, apply your branding, and sell it as your own. No design work or tooling required.
OEM stands for Original Equipment Manufacturing. In this model, you — the brand owner — provide the manufacturer with your own product design, specifications, and technical requirements. The factory's job is to build what you've specified, to the quality standards you've set, and to deliver it at the agreed price and lead time.
The key word here is original. In OEM, you're bringing the original design to the table. This means you need to have done the product development work upfront: ideally you'll have technical drawings, CAD files, material specifications, and a clear idea of the tolerances and quality requirements. The factory doesn't design anything — they manufacture.
Imagine you're a UK fitness brand launching a new resistance band set. You've worked with a product designer to develop a specific band thickness, texture, and packaging design that's unique to your brand. You bring those specs to a manufacturer in Yiwu or Ho Chi Minh City. They quote based on your specs, produce pre-production samples, and once approved, run your full order. That's OEM.
Crucially, with OEM you typically own any custom tooling that's been created (such as injection moulds for plastic components), which means no other brand can copy your exact product from the same factory — unless they pay for the same tooling.
In a proper OEM arrangement, the IP (Intellectual Property) belongs to you, the brand owner. This is especially important for UK businesses given the complexities of cross-border IP protection between the UK and China. You should always have a written agreement that makes clear the design is your property, and that the factory cannot produce the same design for other customers.
OEM isn't cheap upfront. Depending on your product category, you might be looking at:
The payoff is a product that's genuinely yours — one competitors can't buy off the shelf and rebrand. For businesses building long-term brand equity, that exclusivity is worth every penny.
ODM stands for Original Design Manufacturing. In this model, the manufacturer already has a product they've designed and produce. You — the brand owner — select a design from their existing catalogue, customise it to varying degrees (colours, logos, packaging, minor tweaks), and sell it under your own brand name.
Think of it like buying a white-label car but painting it your brand colour and putting your badge on it. The engine, chassis, and interior are all standard — but the badge says "you."
Let's say you're launching a line of eco-friendly travel mugs for a UK outdoor brand. You find a factory in Guangdong that makes a stainless steel double-walled mug that's already been tested, certified, and is in active production for dozens of other brands globally. You choose the colour, specify your logo position, design your packaging, and order 300 units. That's ODM.
The beauty of ODM is speed and lower risk. There's no tooling to pay for, no R&D phase, no expensive prototyping cycle. The product has already been market-tested — often by dozens of brands before you. You're effectively licensing an existing product design and putting your name on it.
ODM isn't always entirely off-the-shelf. There are degrees of customisation available:
The differences between OEM and ODM go beyond just who designs the product. They affect your upfront costs, your timeline, your IP position, your competitive differentiation, and your legal responsibilities — particularly around UKCA marking and product liability in the UK market.
In OEM, the design is yours. Full stop. You created it, you own it, and the factory is a contractor. In ODM, the factory owns the design. You're licensing it (often informally). This distinction matters enormously if you ever want to change factories — with OEM, you can take your technical files and move; with ODM, you're tied to whichever manufacturer holds the original design.
ODM is significantly faster. Because the product already exists, you can be from "initial enquiry" to "goods in the container" in as little as 30–45 days for simple products. OEM, with its product development, tooling, and sampling phases, typically takes 90–150 days for a first run.
OEM has higher upfront costs (tooling, development) but often lower per-unit costs at scale because you control the specifications completely. ODM has very low entry costs but you pay a small premium per unit compared to what the factory charges bulk ODM customers.
This is where the real strategic difference lies. If you're selling on Amazon UK or to UK retailers, and five other brands are selling the exact same ODM product with different logos, it's very hard to command a premium. OEM gives you genuine product differentiation — something no one else has. That translates into pricing power, brand loyalty, and defensibility.
| Factor | OEM | ODM |
|---|---|---|
| Who designs the product? | You (the brand owner) | The manufacturer |
| IP ownership | Yours | Manufacturer's |
| Upfront tooling cost | £500–£15,000+ | £0–£500 |
| Typical MOQ | 500–2,000+ units | 50–500 units |
| Lead time (first order) | 90–150 days | 30–60 days |
| Product exclusivity | High — your design only | Low — shared design |
| Customisation level | Full — any specification | Limited — colours, branding |
| Risk level | Higher (design risk) | Lower (proven product) |
| Price per unit at scale | Lower (optimised spec) | Slightly higher |
| Best for | Established brands, unique products | Start-ups, market testing |
| Can switch factories? | Yes — you own the files | Limited — design stays with factory |
The honest answer is: it depends on where you are in your business journey, how differentiated your product needs to be, and how much capital you have available upfront.
Many of the most successful UK brands we work with started ODM and evolved into OEM. They used ODM to test the market with low risk and minimal capital, then — once they had proof of demand — invested in OEM development to lock in exclusivity.
When starting with ODM, ask the manufacturer whether they offer an upgrade path. Some factories will let you pay for custom tooling modifications later, effectively converting your ODM product into a semi-OEM version — giving you exclusivity without starting from scratch.
One of the most common questions we get from UK clients is: "How much will this actually cost me?" The honest answer is that it varies — a lot — by product category, factory tier, and whether you're in China or Vietnam.
| Product Category | Tooling Cost | Typical MOQ | Lead Time (China) | Lead Time (Vietnam) |
|---|---|---|---|---|
| Simple plastic consumer goods | £500–£3,000 | 500–1,000 units | 60–90 days | 75–100 days |
| Electronics / tech accessories | £2,000–£10,000 | 1,000–5,000 units | 90–120 days | 100–130 days |
| Clothing / textiles | £200–£2,000 (patterns) | 300–1,000 units per style | 60–90 days | 60–90 days |
| Furniture / homeware | £1,000–£8,000 | 200–500 units | 75–100 days | 80–110 days |
| Gym / sports equipment | £1,500–£12,000 | 500–2,000 units | 90–120 days | 100–130 days |
| Product Category | Customisation Cost | Typical MOQ | Lead Time (China) | Lead Time (Vietnam) |
|---|---|---|---|---|
| Consumer lifestyle goods | £0–£500 | 100–300 units | 30–45 days | 40–55 days |
| Electronics accessories | £0–£300 | 200–500 units | 30–50 days | 45–60 days |
| Clothing / accessories | £0–£200 | 50–200 units per style | 25–40 days | 30–45 days |
| Homeware / kitchenware | £0–£400 | 100–300 units | 30–50 days | 40–55 days |
| Promotional / gift items | £0–£100 | 50–200 units | 20–35 days | 30–45 days |
Note: these lead times are production lead times from factory. Add 25–35 days sea freight time to Felixstowe or Southampton from China, or 30–35 days from Vietnam.
This is where UK businesses need to pay very close attention — and frankly, it's where most OEM/ODM guides written for a global audience let UK importers down badly.
Since the UK left the EU, CE marking alone is no longer sufficient for most product categories sold in Great Britain (England, Scotland, and Wales). The UK Conformity Assessed (UKCA) marking has replaced CE for the majority of regulated products sold on the GB market. Northern Ireland is subject to separate rules and can still use CE marking in many cases.
If your product falls into a regulated category (electrical goods, toys, personal protective equipment, medical devices, machinery, construction products), you are legally responsible for UKCA compliance as the importer — even if the factory handles the testing. Many Chinese and Vietnamese factories offer CE certification but have no knowledge of UKCA requirements. Do not assume CE = UK compliant. It no longer does.
As of mid-2025, the UK government has confirmed that CE marking can still be used in the UK market in most sectors with ongoing reviews — but this is subject to change. Always check the latest HMRC and OPSS guidance before importing regulated products.
In an OEM arrangement, you own the product design. This means you are the "manufacturer" in the eyes of UK product safety law — even though a Chinese or Vietnamese factory physically made it. You bear full legal responsibility for ensuring the product meets UK safety standards, carries the correct UKCA mark, and has the appropriate Declaration of Conformity documentation.
Whether you're importing OEM or ODM products, you'll need an EORI (Economic Operator Registration and Identification) number from HMRC to import goods into the UK. Since HMRC migrated from CHIEF to the Customs Declaration Service (CDS) in 2022, all import declarations must be filed through CDS. Most UK freight forwarders can handle this on your behalf.
Your goods will also need the correct HS (Harmonised System) commodity code for classification under the UK Global Tariff. The duty rate varies significantly by product category — for example, clothing from China attracts 12% import duty, whilst some electronics attract 0%.
All imports from non-UK countries are subject to import VAT at the standard rate of 20%. However, if you're VAT-registered in the UK, you can reclaim this through your VAT return using Postponed VAT Accounting (PVA) — which means no cash flow impact at the border.
Both China and Vietnam are exceptional manufacturing countries — but they serve different needs, and the OEM/ODM landscape differs meaningfully between the two.
China remains the world's largest manufacturing nation and is unrivalled for both OEM and ODM depth. With UK-China trade running at approximately £87 billion in 2024, the supply chain infrastructure, factory capacity, and supplier ecosystem in China is simply unmatched. For OEM, China offers the widest selection of capable factories across virtually every product category.
Vietnam has emerged as a serious OEM alternative — particularly for clothing, footwear, textiles, furniture, and electronics. UK-Vietnam trade reached approximately £9.6 billion in 2024, and with the UK-Vietnam Free Trade Agreement (UKVFTA) in force, UK importers sourcing from Vietnam can benefit from significantly reduced import duties.
Under UKVFTA, 65% of UK import duties on Vietnamese-origin goods were eliminated immediately upon the agreement coming into force, with that figure rising to 99.2% over the implementation period.
| Factor | China (OEM/ODM) | Vietnam (OEM/ODM) |
|---|---|---|
| UK import duty | UK Global Tariff (varies 0–12%+) | UKVFTA preferential (often 0–5%) |
| ODM catalogue depth | Enormous — every category | Strong in textiles, furniture, electronics |
| OEM capability | Very high across all categories | High in key sectors, growing |
| MOQs | Generally higher | Generally lower (good for small brands) |
| Labour costs | Higher (rising) | Lower (approx 30–40% cheaper) |
| Sea freight to UK | 25–30 days | 28–35 days |
| English communication | Moderate (improving) | Strong in larger factories |
Importing 2,000 units of clothing from China: 12% duty on £20,000 CIF value = £2,400 in duty.
The same goods from Vietnam under UKVFTA at 0%: £0 in duty. That's a £2,400 saving on a single shipment.
After working with hundreds of UK importers, we've seen the same mistakes come up time and again. Here's what to watch out for — and how to avoid them.
We see this constantly — a first-time UK brand owner, excited about their idea, jumps straight to OEM because they want a "unique" product. They spend £8,000 on tooling and 4 months on development, only to discover that an almost-identical ODM product was already available at 40% lower cost. Always check the ODM landscape thoroughly before committing to OEM development.
Just because a Chinese factory has CE certification on an ODM product doesn't mean it meets UK requirements. UKCA compliance is your responsibility as the UK importer. We've seen UK businesses receive letters from Trading Standards about non-compliant products — not because the factory was fraudulent, but because the buyer didn't understand their compliance obligations.
If you pay for injection moulds or other tooling, make sure your agreement with the factory clearly states that the tooling is your property. Without this, you may find that the factory holds your moulds "hostage" if a dispute arises. This should be in a written contract, not just a verbal understanding.
First samples are almost never perfect. Budget for 2–4 sampling rounds minimum for OEM products. Each round costs time (2–4 weeks per round) and money (sample fees, courier costs from China or Vietnam to the UK, usually £40–£120 per sample shipment). Factor this into your timeline — if your seasonal product needs to land at Felixstowe by October, you need to start development in March at the latest.
In China particularly, the standard NDA isn't always the most effective tool. A better structure is an NNN agreement — Non-Disclosure, Non-Use, Non-Circumvention. This prevents the factory not just from disclosing your design, but from using it themselves or selling it to others. For OEM products, this is essential.
If you're going ODM, ask the factory whether they offer exclusivity — i.e., they won't sell the same product to your direct competitors in the same market. Some factories will agree to regional exclusivity for a small premium.
Factories in China and Vietnam deal with dozens or hundreds of buyers. They will often use vague language like "don't worry, we never sell to your competition" — without putting anything in writing. Get it in writing, or assume it isn't true.

Yes, and this is actually a very common and sensible strategy. Many of the UK brands we work with start with ODM to test market demand with low risk, then transition to OEM once they've validated demand and have the budget to invest in product development. The key thing to know is that your ODM supplier may or may not be able to develop your OEM product — they're not always the same type of factory. When you're ready to make the transition, we can help you find an OEM-capable factory and manage the development process from scratch.
You are. As the UK importer, you are legally the "importer" in UK product safety law, and in many OEM cases you're treated as the "manufacturer." This means you bear responsibility for ensuring the product meets UK safety requirements, carries appropriate UKCA marking (where required), and is backed by a valid Declaration of Conformity. Chinese factories can assist with testing and documentation, but the legal responsibility sits with you.
These terms are often used interchangeably in the market, which causes a lot of confusion. Strictly speaking: OEM refers to products manufactured to your design and specification; white label is a common term for ODM products that you rebrand. When talking to factories, always specify what you mean: either "I have my own design for you to manufacture" (OEM) or "I want to put my brand on one of your existing products" (ODM).
Trading companies present themselves online (particularly on Alibaba) as manufacturers, but they're actually middlemen who add a margin on top of the actual factory price. For OEM projects, working with a trading company typically means slower communication, less design control, and higher costs. The best way to verify whether you're dealing with a genuine factory is a physical audit — either by visiting yourself or by hiring a local agent like Epic Sourcing to verify on your behalf. Our supplier verification service covers exactly this.
Not necessarily better — but it can be better for specific categories and for UK businesses with the right requirements. Vietnam excels at OEM in textiles, clothing, footwear, basic furniture, and electronics assembly. Its advantages for UK buyers include lower labour costs, excellent UKVFTA duty savings, and increasingly strong factory capability. China still leads in product diversity, supply chain depth, and complex OEM capabilities. Many smart UK brands dual-source — using China for complex OEM and Vietnam for simpler or duty-sensitive categories.
