It depends upon your costing method and mechanism for processing the insurance (misc. charges?) however if you look at the inventory transaction it will tell you the financial cost and charges etc.
Check the Inventory Transactions for the Item, you will find the Cost amount for the Item. On the On hand form you can find the Cost amount and the Financial amount.
Also, Cost updated depends on the costing method attached for the Item.
Well I don’t know if I did explain well but, what I’m looking for is the cost price related to one importation, not the weighted-average purchase price shown on the cost amount.
