Article 27 of Directive 92/83/EEC on excise duties on alcohol and alcoholic beverages states that in order to benefit from the excise duty exemption, alcohol not intended for human consumption must be denatured in accordance to required methods laid down at national level.
The Directive distinguishes between:
- Completely denatured alcohol (CDA) (Article 27 (1) (a)) - This is predominantly alcohol for industrial use. There is a new "Euro" formulation used by the majority of Member States for completely denatured alcohol (CDA) of (per HL of absolute alcohol):
- 1L methyl ethyl ketone (a smelling agent)
- 1L isopropyl alcohol (a chemical analytical marker)
- 1gr denatonium benzoate (a tasting agent)
In a few Member States, there are varying combinations of the quantities of two of the three chemical agents, but all three chemical agents are present in all of the Member States "Euro" formulations for CDA.
There is also a significant reduction in the number of national CDA formulations in use. Member States can still maintain their own national denaturing formulations for CDA, which must then be notified and authorised at EU level. Completely denatured alcohol must have a simplified accompanying document (SAD) when moving within the EU (Commission Regulation (EEC) 3649/92).
- Partially denatured alcohol (PDA) (Article 27 (1) (b)) - Member States authorise national processes for "partial denaturation". These processes are used to denature alcohol in products not intended for human consumption but for which the rules on completely denatured alcohol are not suitable. Examples of such products include cosmetics, perfumes, hygiene products, bio-fuels, screen wash, anti-freeze, inks, cleaning materials etc. A finished product containing partially denatured, which is manufactured in one Member State, in line with EU provisions, may circulate freely in the Single Market, without the need for accompanying documents.
Article 15 (2) of Directive 2008/118/EC on common excise duty provisions states that production, processing and holding of excise goods, where the excise duty has not been paid, must take place in a tax warehouse.
It follows then that the denaturing process must take place in a tax warehouse. This is to ensure proper oversight of the denaturing process and prevent alcohol on which excise duty has not been paid from being released into circulation and illegally sold for consumption.
