Goods Damage Entry

All right, I can help you because AS, Indas has the same treatments for inventory.

There are two aspects here like costing and AS which I have to confirm. Will get back to you soon.

As per the Costing principles, waste/spoilage must be identified between Normal and abnormal.

Normal waste is included into the finished goods cost or inflate the purchase price/unit to meet the waste cost. 

Abnormal waste/ spoilage is expensed.

If it is an agricultural product, the measurement is like 'fair value of the produce' and the biological assets standard does not mention waste treatment and however all inventory principles can be applied incase of no prescribed treatment. When this damage occurred in the warehouse, your lucky that you dont have to do inventory under/overvaluation because there is no diminution in price but complete loss. Just write it off like

Dr. Inventory loss

Cr. Inventory

This is because you are saying its abnormal spoilage. If you want to consider it as normal waste then 

Dr. Inventory

Dr. Waste capitalised or spread evenly over inventory or batch

Cr. Closing inventory P&L

But if your just a trader in a shop only and not the farmer, according cost CIMA, evaporation is a normal waste and you must charge this cost on other products. But, If the loss appears abnormal then write it off.

Simple!!
