Which of the following is NOT a type of inventory mentioned in NAVSUP P-486?

The correct answer is that seasonal inventories are not a type specified in NAVSUP P-486. This publication outlines the types of inventory used in Navy logistics and supply, focusing on categories that support effective inventory management and accountability.

Spot inventories are conducted to verify the existence and condition of specific items at random times, supporting accuracy in stock levels. Breakout inventories refer to the process of extracting supplies from warehouse storage for immediate use in operational settings. Storeroom inventories involve the systematic checking and counting of items stored in a storeroom to ensure proper accounting.

In contrast, seasonal inventories are not specifically addressed in NAVSUP P-486, as they relate more to commercial sectors where certain products might be stocked according to seasonal demand, which does not align with the structured inventory types focused on by Navy supply procedures.
