Hazmat Endorsement TSA Background Check, Explained (2026)

Every driver adding a hazmat endorsement must pass a TSA security threat assessment, a fingerprint-based background check that costs $85.25 and usually clears in a few days to several weeks. It is typically the slowest step in getting your H endorsement, so the best move is to apply as early as possible.

For the full picture of the endorsement, see our guide to what a hazmat endorsement is and how to get it.

What the TSA threat assessment is

The Transportation Security Administration screens every hazmat applicant to confirm they do not pose a security threat. The check covers criminal history, immigration status, and terrorism and intelligence databases. Your state will not add the H endorsement until the TSA reports that you passed.

How to apply

1. Pre-enroll online through the TSA's Hazmat Endorsement Threat Assessment Program (HTAP) enrollment site, or schedule by phone.
2. Visit an enrollment center with your CDL and proof of citizenship or lawful immigration status.
3. Get fingerprinted and pay the fee at your appointment.
4. Wait for the result. The TSA notifies your state, and you receive a determination letter.

Check your state's rules first. A few states run their own enrollment process, but the federal standards are the same.

How much it costs

The fee is $85.25 (TWIC holders may qualify for a reduced rate of $41) and is the largest fixed cost of the endorsement. If you already hold a current TWIC card or another TSA-approved credential, you may qualify for a reduced fee. For every other fee involved, see the hazmat endorsement cost breakdown.

How long it takes

Many drivers clear within a few days to about two weeks, but it can take 30 to 60 days or longer if your record needs extra review or documents are missing. Apply on the same day you start your training, not after you pass the knowledge test.

What can disqualify you

The TSA has two main lists of disqualifying criminal offenses:

• Permanent disqualifiers include espionage, sedition, treason, terrorism, murder, and certain crimes involving explosives or transportation security incidents.
• Interim disqualifiers apply if you were convicted within the last seven years, or released from prison within the last five, for offenses such as unlawful firearms or explosives possession, extortion, fraud, bribery, smuggling, distribution of controlled substances, arson, kidnapping, robbery, and serious assault.

You can also be disqualified if you are not a U.S. citizen or lawful permanent resident (or in another eligible immigration category), if you are under want or warrant for a disqualifying crime, or if you have been adjudicated as lacking mental capacity.

Appeals and waivers

If you receive a preliminary denial, you can appeal if you believe the record is wrong, or request a waiver for certain offenses by showing rehabilitation. Respond quickly and follow the instructions in your letter.

Renewal

The threat assessment must be renewed along with the endorsement, generally about every five years, and the fee applies again.

Avoid delays

• Bring the exact identity and citizenship documents the TSA requires.
• Make sure the name on your documents matches your CDL.
• Start the check the same week you begin your $18.99 Hazmat ELDT theory.
• Use the waiting time to study. Our guide on how to pass the hazmat endorsement test is a good place to start.

The bottom line

The TSA check is simple but slow. Pre-enroll, bring the right documents, pay the $85.25 fee, and apply early so your background check is cleared by the time you pass the test.
