Getting a hazmat endorsement takes a knowledge test and a federal background check. Keeping it takes the background check again, on a schedule, and the second time catches more drivers out than the first. The endorsement does not simply renew alongside your CDL. Every renewal requires a new Transportation Security Administration security threat assessment, with new fingerprints, and the state cannot renew the endorsement until TSA clears you. Start too late and the endorsement can lapse, which means you cannot haul placarded loads until it is restored. This guide walks through the renewal timeline, the rules behind it, the fee, the TWIC shortcut, what happens when you move states, and the safety net if TSA is slow.
This is general guidance, not legal advice. Rules and procedures vary by state, so confirm the details with your state licensing agency and with TSA.
The short version
| Step | What happens | Timing |
|---|---|---|
| State notice | Your state tells you renewal requires a TSA assessment | At least 60 days before expiry |
| Enroll with TSA | Apply online or in person, give fingerprints, pay the fee | Any time after the notice, no later than 60 days before expiry |
| TSA review | TSA runs the security threat assessment | Goal: status within 60 days of enrollment |
| State renews | Your state issues the renewed endorsement once TSA clears you | Before the expiry date if you started on time |
| Knowledge test | Some states require the hazmat test again | Check your state rules |
The single most useful number on this page is 60. Your state warns you at least 60 days ahead, TSA wants your application at least 60 days ahead, and TSA’s goal is to give you a status within 60 days. If you wait for the deadline to get close, those 60 days collide.
Why renewal needs a new background check
The hazmat endorsement exists because placarded loads can be dangerous in the wrong hands, and federal law treats the right to haul them as a security question as well as a safety one. Under 49 CFR 383.141, a state may not issue, renew, upgrade or transfer a hazmat endorsement unless TSA has determined the driver does not pose a security threat, and states must require renewal every five years or less, so that every hazmat driver is screened at least every five years.
TSA’s own rule, 49 CFR 1572.13, says the same from the other side: no state may issue or renew a hazmat endorsement unless it receives a Determination of No Security Threat from TSA.
So a renewal is not a paperwork formality. It is a fresh check of criminal history, immigration status and other factors, covered in our guide to hazmat endorsement disqualifying offenses. A conviction since your last assessment can affect the result.
Step 1: the state notice
Both federal rules require your state to notify you at least 60 days before your endorsement expires that renewal will require a TSA security threat assessment.
There is a small difference in the wording. TSA’s rule says the notice must tell you that you may start the assessment any time after receiving the notice, but no later than 60 days before the expiration date. The FMCSA rule says the notice must advise you to file a renewal application as soon as possible, and not later than 30 days before expiry. The practical answer is to follow the stricter one: start no later than 60 days out, and earlier if you can.
Do not rely on the notice arriving. Mail goes astray and addresses change. Put your endorsement’s expiry date in your calendar now, with a reminder at 90 days.
Step 2: enroll with TSA
According to TSA’s hazmat endorsement page, you can pre-enroll online or complete the whole process in person at an enrollment center. At the center you provide documents for citizenship or immigration verification, give fingerprints, and pay the fee.
Fingerprints are required at every renewal. TSA’s guidance says you will be required to submit new fingerprints at the time of renewal of the endorsement. Old prints from your first application are not reused.
Eight states run enrollment through the DMV. TSA says applicants from Florida, Kentucky, Maryland, New York, Pennsylvania, Texas, Virginia and Wisconsin should visit their local Department of Motor Vehicles for application and fingerprinting information rather than a standard TSA enrollment center. If you live in one of those states, start with your DMV.
TSA recommends booking an appointment; walk-ins are accepted, but appointments take priority.
The fee
TSA lists the fee, effective 1 January 2025, as $85.25 for new and renewing applicants. The reduced rate is $41.00, for applicants who already hold a valid TWIC card and are licensed in a state that accepts the TWIC security threat assessment. The fee is non-refundable, so check your eligibility before you pay.
Step 3: the TSA review
TSA says its goal is to provide the status of your application within 60 days of receiving the information you gave at enrollment, and that it can take longer if fingerprints were hard to capture or data is missing. TSA’s page also notes increased demand and recommends that all applicants, including renewals, enroll at least 60 days before they need an eligibility determination.
You can check your status online. In the eight DMV states, TSA directs applicants to check status with the state licensing agency.
Two things speed the review up: complete, accurate information on the application, and clear fingerprints. If an enrollment agent says your prints did not capture well, ask whether they should be retaken before you leave.
Step 4: the state renews
Once TSA sends a Determination of No Security Threat, your state can renew the endorsement. Depending on the state, that may happen automatically at your next license transaction, or you may need to visit or apply.
Some states also require you to retake the hazmat knowledge test at renewal. TSA’s guidance notes that, per state requirements, you may be required to pass written tests before a new, renewed or transferred endorsement is issued. If your state requires it, our guides on how long to study for the hazmat test and the five-minute hazmat study routine are a quick refresher, since five years is long enough to forget placard details.
The TWIC shortcut
If you already hold a Transportation Worker Identification Credential, you may have two ways to save time or money:
- Reduced fee. TSA offers the $41.00 reduced HME rate to TWIC holders in states that accept the TWIC assessment. TSA’s page lists the participating states and how much time must remain on the TWIC assessment.
- HME on the strength of a TWIC. Under the TSA Modernization Act of 2018, states may issue a hazmat endorsement to a driver who holds a valid TWIC, using the TWIC to verify the TSA assessment. The endorsement then expires no later than the TWIC.
That second point is worth thinking through. If your TWIC expires soon, an endorsement tied to it will expire soon too, so a full renewal may make more sense. Our comparison of TWIC and the hazmat endorsement explains how the two credentials relate.
Moving to another state
If you move and transfer your CDL, you do not automatically need a new threat assessment. TSA’s rule says the new state will not require a new assessment until the renewal period from the previous state, not to exceed five years, expires. TSA’s guidance puts it as: you may not need a new assessment if your new state can issue an endorsement that expires within five years of your last completed assessment.
In practice, that means the clock follows your last assessment, not your new license. A driver who moves four years after their last assessment will face renewal within about a year, even with a brand new license in hand. Ask the new state how it handles the endorsement’s expiry date when you transfer.
If TSA is slow: the 90-day extension
TSA’s rule gives states a safety net. If TSA has not provided a determination before your endorsement’s expiry date, the state that issued it may extend the expiration date for 90 days, and any further extension must be approved in advance by TSA.
That extension is discretionary, and it only helps drivers who applied in time for the delay to be TSA’s. It is not a substitute for applying early.
What happens if the endorsement lapses
If your endorsement expires before it is renewed, you lose the authority to drive vehicles that require placards. Your CDL itself may still be valid for other loads, but placarded hazmat work stops until the endorsement is restored, which means a new assessment and possibly a new knowledge test. For drivers whose income depends on tanker or hazmat freight, that gap can be expensive. The X endorsement, which combines tanker and hazmat, is affected the same way, because the hazmat half depends on the same assessment.
Driving a placarded load without a valid endorsement is also a serious violation for both driver and carrier; our guide to hazmat fines and penalties gives a sense of what is at stake.
Common renewal mistakes
Assuming the CDL renewal covers it. Renewing your license at the counter does not clear the TSA assessment. The endorsement needs its own clearance.
Waiting for the letter. The state notice is a requirement on the state, not a guarantee it reaches you. Track the date yourself.
Paying the full fee when the reduced one applies, or the reverse. Check TWIC eligibility before paying a non-refundable fee.
Moving states and losing track of the clock. The assessment date follows you. A new license does not reset it.
Skipping the refresher. If your state retests, five years of driving does not guarantee you remember segregation tables or placard thresholds.
A renewal checklist
- Know your expiry date. Write it down and set reminders at 90 and 60 days.
- Check your state’s process. Standard TSA enrollment or DMV, test or no test.
- Check whether a TWIC helps. Reduced fee, or an HME based on your TWIC.
- Enroll early. Pre-enroll online, book an appointment, bring your documents.
- Give clear fingerprints. Ask for retakes if capture was poor.
- Track your status. Online, or through your state in the DMV states.
- Refresh your knowledge. Especially if a test is required.
- Confirm the renewed endorsement appears on your license and in your carrier’s records.

Frequently asked questions
How often do you renew a hazmat endorsement?
At least every five years. Federal rules require states to renew hazmat endorsements every five years or less, and each renewal requires a new TSA security threat assessment. Some states use shorter cycles to match their license renewal periods.
Do you need new fingerprints to renew a hazmat endorsement?
Yes. TSA’s guidance says applicants must submit new fingerprints at the time of renewal of the endorsement.
How early should you apply to renew a hazmat endorsement?
No later than 60 days before the endorsement expires, and earlier if possible. TSA’s rule sets the 60-day point, TSA’s goal is to give a status within 60 days of enrollment, and processing can take longer.
How much does it cost to renew a hazmat endorsement?
TSA lists $85.25 for new and renewing applicants since 1 January 2025, or $41.00 for eligible TWIC holders in participating states. Your state may charge its own license fees on top.
What is the best way to prepare for a hazmat retest at renewal?
Short daily sessions on placard recognition and the most-tested rules work well after a five-year gap. An app such as CDL Placards helps you relearn the placards quickly, and your state CDL manual remains the authority for the test.
