What classification does an initial requirement due to new or increased allowance fall under?

The classification of an initial requirement due to new or increased allowance falls under 5D. This category specifically addresses new or additional requirements that arise from changes in allowance lists or the need for new items. When the Navy recognizes a need for additional repair parts or equipment—either due to increased operational demands or changes in mission scope—those requirements are categorized as 5D.

The other classifications represent different types of requirements: for example, 5A generally pertains to modifications or adjustments to existing allowances, while 5G is focused on requirements tied to fleet support. Similarly, 5S is related to specific supply support needs. Understanding these classifications helps repair parts petty officers (RPPOs) categorize and prioritize supply requisitions effectively, ensuring that the right parts are available to meet operational needs.
