The 100 ml shortfill, reviewed against a duty that does not care about nicotine

Most of what is reviewed on this site is a device or a document. The shortfill is neither: it is a packaging decision, a large bottle of nicotine-free base sold deliberately underfilled so a separate nicotine shot can be tipped in at home. It exists because the container-size and strength limits in the Tobacco and Related Products Regulations 2016 are, as the trade reads them, written around nicotine-containing refill containers, leaving a bottle with no nicotine in it outside them — background this review takes as read, since the instrument itself would not open for us to check. That is the format’s whole design premise, and it is worth reviewing now because a second instrument arrives on 1 October that was drafted with no interest in nicotine at all.

The instrument

The wording matters more than the rate. HMRC’s policy paper on the introduction of the duty says the flat rate is meant to simplify calculation and reporting and to reduce disputes over classification by nicotine content. HMRC’s own one-month reminder to the trade puts it in a single clause: an excise duty on all vaping liquids manufactured in or imported into the UK, whether they contain nicotine or not. Rachel Nixon, HMRC’s Director of Indirect Tax, is quoted there telling manufacturers, importers and warehousekeepers they should already have applied for approval. That approval is permission to carry on an excise activity. It is not a product authorisation and says nothing about any liquid’s safety.

The arithmetic

Do the sum the format invites. A 100 ml shortfill is 100 ml of liquid, which at £2.20 per 10 ml is £22.00 of duty. Add a 10 ml nicotine shot and the finished 110 ml carries £24.20. A conventional 10 ml nicotine-containing bottle carries £2.20 — an identical 22 pence per millilitre.

That is the review’s finding in one line. The shortfill’s proposition was always millilitres per pound: buy the volume, add the nicotine, pay once for the packaging and the courier rather than eleven times. None of that advantage was ever a tax advantage, because there was no tax. From 1 October the per-millilitre duty is the same whichever bottle it comes in, and it scales precisely with the quantity the shortfill was designed to maximise. Any retail price is a separate matter: HMRC notes that whether the duty is passed along the supply chain is a commercial decision, so the figures above are duty arithmetic on stated volumes and not a shelf price anyone has observed.

The ledger

Verdict

A format built around a distinction the 2016 rules drew is being taxed by an instrument that refuses to draw it. The government’s stated objective is reducing the affordability and appeal of vaping products while keeping the financial incentive for smokers to switch, and the flat rate is defended as administrative simplicity. Whatever one makes of that trade, it leaves the shortfill’s case resting on the things it was good at before anyone thought to tax it: pick your own strength, get your flavour, and buy one bottle instead of eleven.

The trade side of this is the part with a deadline attached, and it is the same window that runs alongside the appearance consultation reviewed here. Producers and importers without approval by 1 October cannot produce and may be unable to trade, HMRC says, with sanctions available. Retailers inherit whatever the chain above them decides to pass on.

None of this is a reason to start. What is in the bottle is nicotine, which is addictive; the counter it crosses in the UK is an over-18 one; and the reader this is written for is an adult already vaping, or a smoker weighing the move — no one else.
