The Isle of Man Treasury's Customs and Immigration Division has launched a public consultation on the impact of Vaping Products Duty on businesses that manufacture vaping liquid in the Isle of Man or import it from places other than the United Kingdom. The duty will be introduced on 1 October 2026 as part of the Isle of Man's obligation under the Customs and Excise Agreement 1979 to align its customs and excise legislation with that of the United Kingdom. The duty will apply to vaping liquid, or e-liquid, including liquid made at home from ingredients such as propylene glycol, vegetable glycerine and flavourings, regardless of whether it contains nicotine. From 1 October 2026, affected businesses will have to pay duty at a flat rate of GBP 2.20 per 10 ml of vaping liquid and attach a vaping duty stamp to all retail packaging. The consultation is primarily aimed at Isle of Man manufacturers and importers bringing vaping liquid in from countries other than the United Kingdom. Wholesalers and retailers are only in scope if they import these products directly from outside the UK.
