excise duty stamps of central govt. are printed in
Excise stamp In the UK, excise stamps have been in use for spirits since 2006.(view image) While these are usually printed on the back label of the bottle by the manufacturer rather than being a special security bought from the government, they still have to adhere to strict specifications, such as containing UV-visible inks.[2] UK law does not require such physical stamps for cigarettes, either - instead, the words "UK Duty Paid" are printed in bold on all packs as part of the manufacturing process, while other forms of control are implemented by HM Revenue & Customs to verify that this is indeed the case. Meanwhile, foreign-bought cigarette packets bearing revenue stamps can be widely seen across the UK, mainly due to the comparatively high price of British cigarettes, leading people to (often illegally) import them from abroad.
