Hazmat endorsement threat assessment program

The TSA Hazardous Materials Endorsement Threat Assessment Program conducts a security threat assessment for any individual who plans to obtain, renew, or transfer a hazardous materials endorsement (HME) on a state-issued commercial driver’s license (CDL).

The program was implemented to meet the legal requirements of the USA, which prohibits issuing a license to transport hazardous materials in commerce unless a determination has been made that the driver does not pose a security risk.

The Act further requires that the risk assessment include checks of criminal history records, legal status, and relevant international databases.

If you want to add, renew, or transfer a HazMat endorsement on your CDL, you must apply for a security threat assessment. TSA rules require you to begin applying for the security threat assessment at least 30 days before the expiration of your CDL.

Filling out an application

The first thing you need to do to begin applying is fill out an application form.

You must complete this form and the background check before going to a fingerprinting location. Don’t sign the application until you are at the fingerprinting site because the signature must be witnessed. 

Getting fingerprinted 

After filling the application form, you must submit your fingerprints at an authorized collection site or any TSA location. These services are unavailable on state holidays.

You must show two forms of identification, such as your driver’s license and DOT medical card.

The TSA will mail the results of the fingerprint assessment to you normally within 30 days. Once you receive your notification in your mailbox, you are eligible to apply for the endorsement at the DMV.

Security Threat Assessment (TSA)

The Security Threat Assessment Program involves checking criminal history records, immigration records, and other federal agency records, on any individuals who wish to apply for, renew or transfer an H endorsement.

TSA is conducting name-based checks on all drivers who currently hold an H endorsement to identify drivers who present a security threat to the national transportation system.

In other words, the TSA summarizes the federal requirements including fingerprinting, background checks, appeals, and waiver information. 

TSA is responsible for the assessment and subsequent approval or denial/revocation of the HazMat endorsement based on the background check and fingerprint-based criminal record check.

Procedures: You must complete a Security Threat Assessment Application before submitting your fingerprints at an authorized collection site.

Status (Citizenship and Immigration Status)

Pursuant to federal requirements, H endorsement applicants must have U.S. Citizenship or Permanent Resident Alien status to be eligible to earn a new, renewal, or transfer HazMat endorsement.
