Why we’re flagging this: You may start seeing a new stamp sealing vape packaging in Welsh shops. It is part of a new UK tax system for vape liquids.
Updated: 1 October 2026
What’s changed?
From 1 October 2026, Vaping Products Duty applies to vape liquids made in or imported into the UK, whether they contain nicotine or not.
HMRC says vape products put into retail packaging from that date must have a duty stamp attached.
From 1 April 2027, all vaping products outside special duty-suspension arrangements must carry the stamp.
What does the stamp mean?
The stamp shows that the product is part of the new tax and supply system. It seals the outer pack so the pack or stamp is damaged when opened.
What does the stamp NOT mean?
A duty stamp does not tell you:
- that a vape is safe;
- what is inside the liquid;
- that it is suitable for young people;
- how common the product is.
What about vapes without a stamp?
Before 1 April 2027, an unstamped product is not automatically illegal. Older stock and products under duty-suspension arrangements can affect whether a stamp is required.
What should people in Wales look out for?
- new duty stamps sealing the outer pack;
- claims that the stamp means a product is “safe” — it does not;
- after 1 April 2027, products being sold without the required stamp where no exception applies.
