Application for approval of special denaturants
If you wish to use denaturants other than those generally authorised for the denaturing of alcohol products, you must obtain approval.
Alcohol products can be used tax-free in a variety of legally regulated cases if they have been denatured beforehand.
Denaturing involves the addition of certain denaturants to alcohol products to render it unfit for drinking and consumption.
A distinction is made between "complete denaturing" and "denaturing". Alcohol tax law regulates the cases in which "complete denaturing" or "denaturing" occurs. In the case of (incomplete) denaturing, for example, certain approved denaturants must be used, depending on the intended use of the alcohol used.
If the approved denaturants are unsuitable in individual cases, the competent main customs office can approve other denaturants on application. To do this, you must submit an informal application for the use of a special denaturant to the relevant main customs office. You must justify why the generally approved means are unsuitable for your purposes.
Denaturants that are generally approved in other EU member states are usually approved as special denaturants by the main customs offices. The denaturants generally approved in the other member states, are published on www.zoll.de. The main customs office can request free samples from you for testing purposes.
In the list below you will find the denaturants generally authorised for the different uses. All denaturants that are not on the list are special denaturants for which you need an approval from your main customs office.
