EU Tobacco Products Tax Directive (2011/64/EU) does not provide for e-cigarettes or nicotine refill containers and it is therefore not possible to apply an excise duty on these products.
Until recently there was no regulation governing e-cigarettes or nicotine refill containers so taxing such products is problematic.
However, the new EU Tobacco Products Directive (2014/40/EU), inter alia, provides for the regulation of e-cigarettes. The European Council has now formally adopted the Directive, and it has been in force since 20th May 2014. The Directive, among other things, sets mandatory safety and quality requirements e.g. nicotine content, ingredients and devices, as well as refill mechanisms etc., for e-cigarettes that do not fall under the definition of medicinal products as set out in Directive 2001/83/EC. Member States have two years to transpose the new rules into national law.
In the absence of domestic legislation to regulate these types of products, I do not wish to speculate how much revenue would be raised by imposing the levels of taxation proposed by the Deputy in his question.
I would however point out to the Deputy that e-cigarettes and refill containers are currently subject to the standard VAT rate of 23%.
