Estimate duty for a liquid volume

Example: 10ml → £2.20 duty, or £2.64 with illustrative VAT on duty.

How the vape-duty calculation works

Multiply the total liquid volume in millilitres by £0.22. The rate is the same for nicotine-containing and nicotine-free vaping liquid. For kits, include every filled pod and refill bottle. Empty hardware has no liquid duty.

Examples by liquid volume

Liquid suppliedDuty estimateWith illustrative VAT on duty
2ml pod£0.44£0.53
10ml bottle£2.20£2.64
2ml pod + 10ml refill£2.64£3.17

The VAT column assumes the duty cost is passed on in full at 20% VAT. It does not predict a final shelf price. A supplier’s price may already include duty.

20mg is not 20ml

Nicotine strength describes concentration. A bottle labelled 20mg/ml may contain 10ml of liquid; check the printed volume. Duty is based on millilitres, not nicotine milligrams.

Start date and duty stamps

The duty started on 1 October 2026. From 1 April 2027, retail vaping products outside duty suspension must have a valid duty stamp. Use the stock-date guidance checker for the transition.

This is a product-level estimate, not a duty return. HMRC rounds down total monthly duty liability to the nearest penny.
