In 2014 Lei n.º 82-B/2014, de 31 de dezembro added nicotine-containing liquid (NCL) used to fill or refill electronic cigarettes to the list of products subject to the Special Consumption Tax. The rate of excise was initially set at € 0.60 per ml of nicotine containing liquid.
Additional details concerning product definitions and the details of the tax applied to electronic cigarettes in Portugal can be found in Part II, Chapter III, Tobacco Tax of the Excise Tax Code (Código dos Impostos Especiais de Consumo – CIEC)
Portugal’s 2017 budget cut the tax on nicotine containing liquid in half to € 0.30 per ml. Parliamentary sources indicated the reduced risk of the vapor product contributed to the decrease in the tax rate.
