VPD Enforcement: Duty Stamps and the HMRC Timeline

We’ve taken a look at what Vaping Products Duty actually is and why the government introduced it in recent articles, but this one’s about the bit most people skim past: how HMRC actually enforces VPD. And the enforcement side of VPD is more serious than a lot of the coverage lets on.

Key Takeaways

• Manufacturers, importers and warehousekeepers have been able to apply for HMRC approval since 1 April 2026
• From 1 October 2026, all newly manufactured stock needs a duty stamp before it can be sold
• There’s a six-month grace period for existing stock, running out on 1 April 2027
• After that date, selling unstamped vaping products becomes a criminal offence, not just a fine
• HMRC can seize stock, and in serious cases prosecute, with custodial sentences possible
• None of this changes how you buy or use a vape as a customer, it’s a supply chain compliance system, but it’s worth understanding since it’s part of why prices are shifting from October

Who has to register?

VPD isn’t something individual shops have to register for. The approval requirement sits further up the chain, with:

• UK manufacturers of vaping products, including anyone making liquid at home for commercial sale
• Overseas manufacturers who intend to send vaping products into the UK
• Importers bringing vaping products into the UK
• Warehousekeepers storing vaping products under duty suspension

If you’re a retailer buying finished, duty-paid stock from a proper supplier, you don’t need to apply for anything yourself. What you do need to do is make sure whoever you’re buying from has actually done it, because selling, or even possessing unstamped stock further down the line carries its own penalties, and that bit’s on you, which we’ll get into.

The application timeline

Applications for approval opened on 1 April 2026, a full six months before the duty itself kicks in. HMRC has said processing an application can take around 45 working days, sometimes longer if they need more information, and any business that missed the early window has been left with very little breathing room.

Overseas manufacturers have to appoint a UK representative to handle the application and to buy stamps on their behalf, which adds another layer most people wouldn’t think about unless they’re actually in the supply chain.

What changes on 1 October 2026?

This is the date most of our other articles focus on, since it’s when the duty itself becomes payable and prices start moving. But it’s also the date the stamping requirement goes live for anything newly produced or imported. From this point, any new stock coming into the market needs a valid duty stamp attached before it’s ready to be sold.

It’s also the date the passenger allowance kicks in for anyone bringing e-liquid into the UK for personal use. Travellers will be able to bring in up to 50ml of liquid for personal use without paying the duty, similar in spirit to the duty-free allowances that already exist for tobacco and alcohol.

The six-month grace period

1 October 2026 doesn’t mean every bottle on every shelf suddenly needs a stamp overnight. Existing stock, the stuff already sitting in shops and warehouses before the rules changed, gets a six-month transition window. Retailers can carry on selling stock they already hold, and buying pre-duty stock from wholesalers, without a stamp right up until 1 April 2027.

That’s a genuinely sensible bit of policy design, since it means nobody’s expected to bin perfectly good stock or scramble to relabel thousands of bottles overnight. It just means the industry has a hard deadline to work towards rather than an immediate cliff edge.

What happens after 1 April 2027?

This is where it stops being a compliance issue and starts being a legal one. From 1 April 2027, it becomes a criminal offence to sell or even possess vaping products without a valid duty stamp, unless the products are still held in duty suspension.

The Finance Act 2026 specifically created offences around dealing in unstamped vaping products and the unlawful use of premises for storing them, and the penalties attached go well beyond the kind of civil fine most people picture when they hear “tax non-compliance.”

HMRC has confirmed this can carry a large fine, and in the most serious cases, a custodial sentence.

The penalties, in detail

A few different penalty types are actually in play, not just one blanket fine:

• Selling or dealing in unstamped retail stock: penalties are calculated based on the number of individual retail units involved, not a flat fee per offence. These apply from 1 October 2026.
• Repeat non-compliance: HMRC looks back over a 24 month “relevant period” when deciding whether to escalate penalties for businesses that keep falling short.
• Lost, stolen or misused stamps: approved stamp holders can be penalised for stamps that go missing. A stamp is treated as lost if it hasn’t been affixed to a product and properly activated within 12 months of being issued. The penalty works on the assumption that any missing stamp may have been applied to a 50ml "short-fill" bottle, attracting a potential fine of a whopping £11.00 per stamp.
• Operating without approval: manufacturing, storing under duty suspension, or handling duty stamps without the right HMRC approval is treated as operating illegally from 1 October 2026, and can lead to civil or criminal penalties depending on severity.
• Seizure powers: HMRC can seize unstamped stock outright, and can also remove legitimately stamped stock found on the same premises as unstamped goods, which is a strong incentive for businesses to keep their record keeping watertight rather than assume a few dodgy units won’t be noticed.

What this means if you’re just buying e-liquid

None of the enforcement side changes anything about how you shop. You’re not going to be asked for ID over a duty stamp, and nobody’s coming to check your vape drawer at home. What it does mean is that stock without a valid stamp after April 2027 genuinely won’t be legal to sell, so reputable retailers have every reason to get this right well before the deadline.

If you’re the kind of person who travels a fair bit, the one practical thing worth remembering is the 50ml personal allowance for bringing liquid into the UK from abroad, since that’s the one part of this that touches individual vapers directly rather than businesses.

FAQ

Do I need to register for anything as a customer? No. Registration applies to manufacturers, importers and warehousekeepers, not individual shoppers.

Can shops still sell old stock after October 2026? Yes, for a six month grace period, until 1 April 2027, provided it was already in circulation before the rules changed.

What happens if a shop sells unstamped stock after the grace period? It becomes a criminal offence, with penalties ranging from unit-based fines through to prosecution and possible prison sentences in serious cases, and HMRC can seize the stock involved.

Does this affect how much vaping liquid I can bring back from holiday? Yes, slightly. From October 2026, travellers aged 17 or over can bring in up to 50ml of vaping liquid without paying duty on it.

Is this the same as the price rise from the duty itself? No, they’re related but separate. The duty is what makes the liquid more expensive, the stamp scheme is how HMRC checks that duty’s actually been paid.
