The specific identification method of costing inventories is used when the company sells a limited quantity of high-unit cost items.

Here's why:

1. The specific identification method is a way of assigning costs to inventory that allows for the physical flow of goods to be tracked and costed individually. This method is most useful when the items in inventory are not identical, thus, the method is not suitable when the physical flow of units cannot be determined.

2. When a company sells large quantities of relatively low cost homogeneous items, methods like FIFO (First In, First Out) or LIFO (Last In, First Out) are typically used. These methods are more efficient for large quantities of similar items.

3. Similarly, for large quantities of relatively low cost heterogeneous items, the weighted average cost method is often used. This method averages out the cost of all the items in inventory to assign a cost to each unit.

4. The specific identification method is most suitable when a company sells a limited quantity of high-unit cost items. This is because these items are often unique or easily distinguishable, making it possible to track the cost of each individual item. Examples of businesses that might use this method include car dealerships, real estate companies, or jewelry stores.
