Denaturation and market separation

The market separation between taxed ethanol for potable purposes and foodstuffs, and untaxed ethanol for industrial purposes, is ensured through denaturation. Denaturation refers to the alteration of the natural smell, flavour or appearance (colour) of a substance by spiking it with additives.

In order to prevent consumption of untaxed ethanol, its production, importation and use are monitored by the Federal Customs Administration.
