The Hazardous Materials Shipper Prioritization Application (HMSPA) is a tool created to help FMCSA personnel generate a list of hazardous materials shippers that need to be inspected. A unique algorithm has been developed which applies information from four databases in order to prioritize shippers based on certain parameters selected by the user of this tool (e.g. by state, service center area, etc.). The prioritization algorithm obtains information from the following four databases:

HMPIP - Hazardous Materials Package Inspection Program

MCMIS - Motor Carrier Management Information System

EMIS - Enforcement Management Information System

HMIRS - Hazardous Materials Incident Reporting System

Further information describing the algorithm and how it works is located on the About Algorithm page.

*It is important to note that this application should be used as a tool in combination with other methods for investigating potential HM Shippers in need of inspection and review. Because not all HM Shippers are in the databases, the results table generated by HMSPA will not contain all the HM Shippers that are in a geographical area
