National Stockpiles: Background and Issues for Congress
The United States maintains several distinct stockpiles of 
request assets and are generally responsible for receiving, 
supplies, equipment, and raw materials that may be used for 
staging, distributing, and dispensing assets. However, in the

services to stockpile managers. The degree to which 
stockpile managers store certain goods, instead of relying 
on pre-negotiated or rapidly executed contracts to deliver 
goods in an emergency, varies. Stockpile managers often 
consider several factors when making a decision to 
stockpile, including: statutory requirements, forecasted 
commercial availability of a product/material, anticipated 
loss of suppliers in a certain geographic area during an 
emergency, forecasted demand during peacetime and 
emergencies, the rareness or criticality of a material, and a 
department’s overall stockpiling strategy. 
Examples of Public Stockpiles 
Federally owned public stockpiles are meant to be deployed 
when a domestic emergency overwhelms local or state 
supplies. Additionally, they may contain specialized assets, 
such as smallpox vaccines unlikely to be stockpiled locally.
