Quick answer: A compliant UK vape product label carries a nicotine warning, "This product contains nicotine which is a highly addictive substance", covering 30% of the front and 30% of the back, plus an ingredients list, nicotine content, a batch number and an enclosed leaflet, all set out in Regulation 37 of the Tobacco and Related Products Regulations 2016. From 1 October 2026 it will also carry a physical duty stamp. If a bottle or box is missing any of this, do not buy it.
What Is a UK Vape Product Label and What Must Be on It?
A UK vape product label is the printed information on an e-liquid bottle or e-cigarette box that the law requires before it can be sold here, not marketing copy the manufacturer chose to add. It exists because vaping products sit under the Tobacco and Related Products Regulations 2016 (TRPR), and Part 6, Regulations 31 to 40, deals specifically with electronic cigarettes and refill containers.
Most shoppers have never read the regulation itself, so the label looks like a wall of small print rather than a checklist. It is not random. Every element on a compliant bottle from Eco Vapours' e-liquids collection traces back to a specific clause: the black-and-white warning block, the ingredients list, the batch code, the leaflet folded into the box. This guide works through each one, what it means, and what it looks like when a product gets it wrong.
What Does "TPD Compliant" Mean on a Vape Product Label?
"TPD compliant" means a product meets the requirements set out in the Tobacco and Related Products Regulations 2016. In practice that covers four things: the physical product (volume and nicotine caps, leak-proof design), the packaging (child-resistant, tamper-evident), the label (the warning, ingredients and batch data), and the paperwork behind it, notification to the Medicines and Healthcare products Regulatory Agency (MHRA) before sale.
A product can only be legally sold in the UK once its manufacturer or importer has notified it to the MHRA and had it published on the public register, under Regulation 31. TPD compliant is not a marketing phrase, it is a factual claim that a specific regulatory process happened before that bottle reached the shelf.
What Does the Vape TPD Warning Label Actually Say?
The wording is fixed by law, word for word. Regulation 37 of the Tobacco and Related Products Regulations 2016, Regulation 37 requires the exact text: "This product contains nicotine which is a highly addictive substance." No retailer can shorten it, soften it, or replace "highly addictive" with something gentler.
The formatting is equally fixed. The warning must be printed in black Helvetica bold type on a white background, positioned parallel to the main text on the pack and centred within its reserved space, sized to fill as much of that space as it can. It must appear twice: covering 30% of the front and 30% of the back of the unit packet when closed. That is not a token strapline in a corner. On a small 10ml nic salt bottle, nearly a third of the front and a third of the back is legally reserved for this one sentence.
That is the single most useful thing to know when you pick up a bottle: if the warning block looks disproportionately large compared to the branding around it, that is the law working as intended, not a design failure. A small, easy-to-miss warning strip is the one that should make you pause.
E-Liquid Label Requirements UK: Ingredients, Nicotine Content and Batch Numbers
Beyond the warning block, Regulation 37 sets out what else has to be printed on the unit packet and any outer container pack: a full ingredients list in descending order by weight, the nicotine content and per-dose delivery, a batch number so a production run can be traced, and a clear instruction to keep the product out of reach of children.
The ingredients list matters more than it looks. It is the only place a genuine allergy or sensitivity concern (propylene glycol intolerance is the most common one raised with UK vape retailers) can be checked before buying, not after a reaction. The batch number matters differently: it lets a manufacturer trace and recall a faulty run, the same mechanism used in food and pharmaceutical labelling, and its presence is one of the fastest tells a product went through a genuine UK compliance process.
Vape Leaflet Requirements: What's Inside the Box and Why
Every compliant nicotine e-liquid unit pack has to include a leaflet, not just a label. Regulation 37 sets out what it must cover: use and storage instructions, including a note that the product is unsuitable for young people and non-smokers, contra-indications, warnings for at-risk groups, possible adverse effects, addictiveness and toxicity information, and contact details for the producer or, if based outside the UK, a UK-based contact.
Where a device refills, the leaflet also has to give refill instructions, including diagrams and nozzle width, tank opening width or docking system details, so a pod or tank can be topped up without spilling liquid. A box with no leaflet at all has skipped a legal requirement, not just a nicety.
Why UK Vape Packaging Rules Cap Bottles at 10ml, Tanks at 2ml and Nicotine at 20mg/ml
Regulation 36 sets the volume and strength ceiling everything else on the label reports back to. Nicotine-containing liquid sold at retail must be in a dedicated refill container no larger than 10ml, or, already inside a tank, pod or single-use device, no larger than 2ml, with nicotine concentration capped at 20mg/ml in either case.
Worked through, that means the absolute maximum nicotine any retail e-liquid bottle can legally hold is 200mg, from 10ml at 20mg/ml. A 2ml pod at the same strength holds a maximum of 40mg. Those aren't arbitrary round numbers, they are the two figures the law multiplies together on every compliant UK bottle, why every 10ml nic salt bottle Eco Vapours stocks tops out at 20mg.
The consequence for buyers is a useful check: a bottle over 10ml labelled above 20mg/ml, or a tank or pod advertised holding more than 2ml, is non-compliant or has come from a market with different rules, and should not be on a UK shelf. This is also the regulation that ended oversized "cloud tanks" holding 5ml or more, common in the US market; nothing legally sold here can exceed the 2ml pod cap, MTL or DTL.
What Is Child-Resistant Vape Packaging, and How Do You Know It's Compliant?
Regulation 36 also requires nicotine-containing products to be child-resistant, tamper-evident, and protected against breakage and leakage. Child-resistant means the closure is designed so a young child cannot easily open it, the same standard applied to household chemicals, typically a push-and-turn or squeeze-and-turn cap rather than a simple twist-off.
Tamper-evident is defined precisely in the regulation: one or more indicators or barriers to entry which, if breached or missing, can reasonably be expected to give visible evidence the product or its packaging has already been opened. In practice that is a shrink band, a foil induction seal, or a snap-off tab, something that cannot be put back once broken. A bottle that twists open with no resistance and no broken seal, straight out of the box, has not met this requirement.
Refillable devices carry a related rule: a nozzle system or docking connection that lets the tank or pod refill without leaking. A pod system that routinely spills liquid on refilling is failing the same safety requirement the child-resistant cap serves.
UK Vape Product Label Checklist: What a Compliant Bottle Looks Like
Put every clause above side by side and it becomes a simple pass or fail checklist, worth screenshotting before your next order, whether a first bottle of nic salts or a bulk restock.
| Label element | What the law requires | Where it comes from | Red flag if missing or wrong |
|---|---|---|---|
| Nicotine warning wording | Exact text: "This product contains nicotine which is a highly addictive substance" | Regulation 37 | Shortened, reworded, or absent from the back of the pack |
| Warning size and style | Covers 30% of the front and 30% of the back, black Helvetica bold on white | Regulation 37 | Small strapline in a corner, coloured or stylised text |
| Ingredients list | Full list, descending order by weight | Regulation 37 | No ingredients printed anywhere on pack or leaflet |
| Nicotine content and per-dose data | Stated clearly, for example, "20mg/ml nicotine salt" | Regulation 37 | No mg/ml figure, or a figure above 20mg/ml |
| Batch number | Present, traceable to a production run | Regulation 37 | No batch code anywhere on the packaging |
| Enclosed leaflet | Use, storage, warnings, contraindications and contact details | Regulation 37 | Bottle and box only, no leaflet inside |
| Bottle or pod volume | Maximum 10ml refill bottle, maximum 2ml tank or pod | Regulation 36 | Bottle over 10ml or tank or pod advertised over 2ml |
| Nicotine strength | Maximum 20mg/ml | Regulation 36 | Any strength above 20mg/ml |
| Child-resistant cap | Cannot be opened easily by a young child | Regulation 36 | Plain twist-off cap with no resistance |
| Tamper-evident seal | Visible broken seal, band or foil once opened | Regulation 36 | No seal, or seal already broken on a "new" bottle |
Eco Vapours' own Candy King On Salts nic salt review is a useful worked example: a standard 10ml nic salt bottle, capped at 20mg, carrying the full warning block, ingredients and batch data this table describes, exactly what every legitimate UK nic salt bottle should show.
What Vape Packaging Rules UK Ban: Health Claims, Cartoons and Discount Offers
Regulation 38 is the part of the law that stops packaging turning into advertising. It bans anything on an e-cigarette or refill container pack that creates a false impression about the product's characteristics, health effects, risks or emissions, and specifically rules out claims that a product is less harmful than other e-cigarettes, or that it has vitalising, energising, healing, rejuvenating, natural or organic properties. None of those words can legally appear on the packaging itself.
It also bans packaging resembling a food or cosmetic product, the juice-carton or sweet-wrapper styling that has caused UK trading standards concern about products appealing to children, references to taste, smell or additives beyond the flavour name, environmental claims, and printed vouchers or two-for-one offers on the pack itself. That last point is about the unit pack, not what a retailer advertises on its own website, where multibuy offers on nic salts remain normal and legal.
Put together, this regulation is why a compliant vape product label reads as plain and text-heavy rather than confectionery branding. A box leaning into cartoon mascots, dessert imagery beyond a flavour name, or "healthier than smoking" wording on the pack itself has stepped outside what UK law allows.
The Vaping Products Duty Stamp From 1 October 2026: What Changes on the Label
A new physical marking is joining the label from 1 October 2026. Under the Vaping Products Duty and Vaping Duty Stamps scheme, confirmed in gov.uk guidance on handling wholesale or retail vaping products, every vaping product released to the UK market from that date carries a duty stamp: a rectangular 42mm by 18mm stamp, roughly a large postage stamp's footprint, fixed to the outermost packaging so it cannot be opened without visibly damaging it.
The stamp confirms Vaping Products Duty has been paid, a flat rate of £2.20 per 10ml of vaping liquid plus VAT, applied regardless of nicotine strength, so even a 0mg shortfill carries the same duty as a 20mg nic salt bottle of the same size. Registration opened on 1 April 2026, six months ahead of the stamp requirement.
There is a practical grace period worth knowing before this autumn. Stock manufactured or imported before 1 October 2026 can still be sold without a stamp until 31 March 2027. After that cut-off, unstamped product has to come off the shelf entirely, returned to the supplier, exported or destroyed, and retailers are expected to show, with supplier invoices and production dates, that older stock genuinely predates the scheme.
How Much Will Vaping Products Duty Add to Your E-Liquid?
The maths is straightforward once the flat rate is set against real bottle sizes, worth doing before autumn 2026 arrives since nobody in the category is publishing this comparison yet.
| Product | Size | Duty added (excl. VAT) | What that means at checkout |
|---|---|---|---|
| Nic salt bottle | 10ml | £2.20 | One flat charge per bottle, whatever the flavour or strength |
| Shortfill e-liquid | 100ml | £22.00 | Duty alone adds more than most 100ml shortfills currently cost before tax |
| Prefilled pod, 2ml | 2ml | 44p | Small per unit, but adds up fast across a multi-pod pack |
How to Spot a Non-Compliant or Counterfeit Vape Product Label
Most non-compliant stock in the UK market is not obviously fake, it is stock that has skipped a requirement above, often bought cheaply from outside the normal UK supply chain. The checklist table earlier doubles as a spotting guide, but three patterns come up most often: a warning block that is front-only, undersized, or in the wrong colour and font; missing traceability, no batch number and no leaflet, both cheap to include and cheap for a counterfeiter to skip; and a volume or strength mismatch, a bottle over 10ml, a pod over 2ml, or a strength above 20mg/ml, all flat impossibilities under Regulation 36.
Behind this sits the MHRA notification system described in gov.uk guidance on e-cigarette regulations for consumer products: manufacturers and importers must notify every e-cigarette and e-liquid product to the MHRA, and have it published, before it can be sold in the UK. A product failing several checks above has, in effect, skipped that process, the real definition of "non-compliant" rather than just "poorly printed."
What Happens If a Shop Sells Non-Compliant Vape Products?
For a retailer, selling non-compliant vape stock is a Trading Standards matter, not a paperwork slip. Products that fail Regulation 36 or 37, or make a claim banned under Regulation 38, can be seized, with enforcement action independent of the duty stamp scheme. From October 2026, the stamp adds a second compliance layer about excise duty: a missing, damaged or reused stamp, or unstamped stock past 31 March 2027, is a duty offence on top of any labelling breach.
For a shopper, the risk is smaller but real: a non-compliant product has not been through the same checks, so there is no guarantee the bottle contains what the missing label would have told you. Buying from a retailer that stocks properly labelled, MHRA-notified products, and checking the label yourself, avoids both problems.
TPD Compliance E-Liquid Labels vs Disposable-Era Packaging: What Changed Since the Ban
Since 1 June 2025, single-use disposable vapes have been illegal to sell or supply anywhere in the UK, regardless of nicotine content. Every label requirement in this guide still applied to disposables while they were legal, but the category no longer exists on a compliant UK shelf. Anything still labelled or marketed as a disposable vape with a built-in, non-rechargeable battery describes a product that cannot legally be sold here.
What replaced it is the rechargeable prefilled pod kit and the refillable pod kit, carrying the same TRPR label requirements as any other e-cigarette or refill container: the same 2ml pod cap, the same 20mg nicotine ceiling, the same warning block. Products like the Donut King DK nic salts review show what the current, compliant version of a bar-style nic salt flavour looks like on the label: a familiar flavour concept, sold as a TPD-compliant 10ml bottle rather than inside a banned single-use device.
Vape Product Label Rules for Nic Salts, Shortfills and Hardware
The core Regulation 36 and 37 requirements apply across the category, but three formats show up slightly differently on the shelf.
Nic Salt Nicotine Warning Labels: What's Different
Nic salt bottles are almost always sold near the 20mg/ml ceiling, since that strength suits ex-smokers replacing a cigarette's hit, so the full warning block, ingredients list and batch number apply across Eco Vapours' nic salts range, including the Vaporesso Deliciu V2 nic salts review, another standard 10ml bottle carrying the same compliant label.
Shortfill E-Liquid Labels: Why Some Bottles Carry No Nicotine Warning
A genuinely 0mg shortfill, typically sold in 50ml or 100ml bottles with room to add a nicotine shot, is not "nicotine-containing liquid" under Regulation 36 as sold, so the specific TPD warning is not mandated on the bottle itself. Once a shot is added, the mixed liquid becomes nicotine-containing and should be treated and stored with the same caution.
Device and Hardware Labelling: What to Check on Pod Kits
Devices, the pod kits in Eco Vapours' hardware collection, carry a related but distinct set of requirements under Regulation 36: a maximum 2ml tank or pod, consistent nicotine dosage delivery, and a refill mechanism that does not leak. Where a device is sold prefilled, the e-liquid inside still has to meet the full liquid labelling standard.
Who Needs to Read Every Word of a Vape Product Label, and Who Can Skim It
Not every purchase justifies working through the full checklist. Someone buying a familiar flavour from a UK retailer they already trust can reasonably glance at strength and flavour and move on; the compliance work has effectively been done by choosing a retailer whose whole range is properly labelled.
The read-every-word approach earns its keep in narrower situations: buying from an unfamiliar online seller for the first time, buying in bulk for resale, receiving stock from a new overseas supplier, or being handed a product with no idea where it came from. In each case, the checklist table above takes under a minute and is the fastest way to tell a legitimate UK product from one that should not be on sale.
Vape Product Label Myths: What UK Vapers Get Wrong
The most common myth is that the large black-and-white warning block signals something wrong with the product, a recall notice or a poor print job. It is the opposite: a large, correctly sized warning covering 30% of front and back is exactly what the law requires, and its absence is the actual red flag.
A second myth is that "TPD compliant" printed on packaging is proof of anything by itself; it is a claim, verified only by checking the label. A third is that the 2ml pod and 10ml bottle limits are a UK quirk other markets skip; they are a deliberate safety limit on nicotine per container. A fourth, common this close to autumn 2026, is that the incoming duty stamp replaces the TPD label requirements. It does not: the stamp is a separate excise marking, sitting alongside every Regulation 36 and 37 requirement above.
Is This Vape Product Label Legit? Our Verdict
Our view is straightforward: a label-literate buyer is the best compliance check available, better than trusting a brand name alone. If a bottle shows the full warning wording on front and back, an ingredients list, nicotine content, a batch number, a leaflet and a child-resistant, tamper-evident cap, treat it as compliant. If two or more are missing, buy elsewhere, whatever the price looks like. From 1 October 2026, add the duty stamp to that checklist for stock produced after the cutoff.
UK Vape Product Label FAQ
Q1 What must a UK vape product label legally include?
A compliant UK vape product label carries the nicotine health warning covering 30% of both the front and back surfaces, a full ingredients list in descending order of weight, the nicotine content and per-dose delivery, a batch number, a "keep out of reach of children" notice, and an enclosed leaflet with usage, storage and warning information, all required under Regulation 37 of the Tobacco and Related Products Regulations 2016.
Q2 What is the exact TPD nicotine warning wording on UK vape packaging?
The mandated wording is: "This product contains nicotine which is a highly addictive substance." It must appear in black Helvetica bold type on a white background, parallel to the main text on the pack, sized to fill the 30% of surface area reserved for it on both the front and the back.
Q3 Why are UK e-liquid bottles limited to 10ml?
Regulation 36 caps any dedicated refill container of nicotine-containing liquid at 10ml, and any tank, pod or single-use device at 2ml, with nicotine strength capped at 20mg/ml. The limits cap how much nicotine a single container can deliver, reducing the risk of accidental overexposure, particularly to children.
Q4 What is the UK vaping duty stamp and when does it start?
From 1 October 2026, every vaping product released to the UK market must carry a physical duty stamp, a rectangular 42mm by 18mm security stamp fixed to the outermost packaging so it cannot be opened without visibly damaging it. It confirms Vaping Products Duty, charged at a flat rate of £2.20 per 10ml of liquid plus VAT, has been accounted for.
Q5 Can I still sell or buy vapes without a duty stamp after October 2026?
Stock manufactured or imported before 1 October 2026 can still be sold without a stamp until 31 March 2027. After that date, any unstamped vaping product must come off sale, be returned, exported or destroyed, and retailers are expected to hold records showing genuinely pre-cutoff stock.
Q6 How do I know if a vape product label is fake or non-compliant?
Warning signs include a nicotine warning that is too small, missing from the back of the pack, or worded differently to the exact legal text, no batch number, no ingredients list, no leaflet inside the box, a tank or pod holding more than 2ml, or a bottle over 10ml labelled above 20mg/ml nicotine.
Q7 Can vape packaging say it is healthier than smoking or use words like natural?
No. Regulation 38 bans packaging that claims reduced harm, or uses words like vitalising, energising, healing, rejuvenating, natural or organic. It also bans food or cosmetic-style packaging, references to flavour or smell beyond the flavour name, environmental claims, and printed vouchers or two-for-one offers on the pack itself.
Q8 Do nicotine-free e-liquids need the same warning label?
The TPD nicotine warning and the 10ml, 2ml and 20mg/ml caps apply specifically to nicotine-containing liquid. A genuinely 0mg e-liquid is not bound by the same nicotine warning rule, though good UK retailers still label strength clearly and apply the same child-resistant, tamper-evident packaging standard regardless.
Q9 Is disposable vape packaging still legal to sell in the UK?
No. Since 1 June 2025, single-use disposable vapes are illegal to sell or supply in the UK, regardless of nicotine content. Any label still describing a product as a disposable vape with a built-in, non-rechargeable battery is describing a banned product, not a compliant rechargeable prefilled pod kit.
Q10 Who has to notify a vape product with the MHRA before it can be sold?
The manufacturer or importer, not the retailer, must notify each e-cigarette or e-liquid product to the MHRA and have it published before it goes on sale in the UK. Retailers selling products already notified by their supplier do not need to submit a separate notification themselves.
