# Dutiable Volume
Manage duty relief for cask-conditioned products by defining the volume eligible for duty, to exclude undrinkable sediment.
### COMING SOON
### Dutiable Volume
Under the current UK Alcohol Duty rules, there is a specific relief for **undrinkable sediment** in cask-conditioned alcoholic products. Undrinkable Sediment is sediment that has been identified as unsuitable for consumption and cannot be sold or supplied as a drinkable product. This may include yeast, lees, solids, residues, or product contaminated during production, storage, or handling
To allow for this wastage on cask-conditioned items, Bevica has Dutiable Volume functionality.
#### Bevica Setup
To apply a Dutiable Volume to an item, this first must be enabled in Bevica Setup `Use Item Dutiable Volume` as shown below.
Once this has been toggled on, the `Dutiable Vol. Allowed Variance` field can then be set. This specifies the maximum percentage variance (0-100) allowed between an item's `Unit Volume` and its Unit Volume for Consumption `Dutiable Volume`. It is then used to validate the value entered on the item card.
#### Item Card
On the item card, under the Duty tab, you can set the item's Dutiable Volume as per the below
Once this value is set, the Unit Duty Amount shown on the item card will update to take into consideration the Dutiable Volume. Any duty postings made will use this figure, ensuring the correct volume is used when calculating excise duty amounts.
