Hazmat Disqualifying Offenses: Complete List
TSA applies two categories of disqualifying criminal offenses for the CDL hazmat endorsement under 49 CFR 1572.103: permanent bars (lifetime, no waiver) and interim bars (7-year lookback with waiver option). Knowing where you stand before applying saves $86.50 in TSA fees and weeks of waiting on a denial.

Key Takeaways
- Six offenses are permanent lifetime bars with no waiver: espionage, sedition, treason, terrorism, murder, and weapons-of-mass-destruction crimes (49 CFR 1572.103).
- Interim offenses (arson, robbery, drug distribution, weapons crimes, and others) disqualify you only if you were convicted within the past 7 years or released within the past 5 years, whichever is later.
- There is no blanket felony bar — TSA disqualifies you only if your conviction matches a specific offense named in the regulation.
- The hazmat endorsement and TWIC card share identical disqualification criteria under 49 CFR Part 1572, so a denial on one means a denial on the other.
- Waivers are available only for interim offenses and are granted based on rehabilitation evidence such as stable employment, completed probation, and character references.
- Request your FBI Identity History Summary before applying so you can see exactly what TSA will find and avoid losing the non-refundable background-check fee.

How the Background Check Works
When you apply for a hazmat endorsement, TSA conducts a Security Threat Assessment (STA) that includes three checks: an FBI fingerprint-based criminal history review, an immigration status verification, and screening against intelligence and law enforcement databases. The criminal history check is the most common source of denials.
The process begins when you submit fingerprints at an authorized enrollment center as part of your hazmat endorsement application. Your fingerprints are sent to the FBI, which returns your complete criminal history — every arrest, charge, conviction, and disposition recorded in the national fingerprint database. TSA then compares your record against the disqualification criteria in 49 CFR 1572.103.
The same disqualification criteria apply to both the hazmat endorsement and the TWIC card. If you are disqualified from one, you are disqualified from both.
Permanent Disqualifying Offenses
The following offenses result in a lifetime disqualification from obtaining a hazmat endorsement. There is no waiver available, no time limit that expires, and no appeal process that can overturn these bars. A conviction for any of the following means you can never hold an H or X endorsement on your CDL:
Espionage or Conspiracy to Commit Espionage
Conviction under 18 USC 792-799 for gathering, transmitting, or delivering national defense information to a foreign government or its agents. Includes conspiracy to commit espionage.
Sedition or Seditious Conspiracy
Conviction under 18 USC 2384-2385 for conspiring to overthrow, put down, or destroy by force the government of the United States, or advocating violent overthrow of the government.
Treason
Conviction under 18 USC 2381 for levying war against the United States or adhering to the enemies of the United States, giving them aid and comfort.
Terrorism or Material Support of Terrorism
Any conviction for acts of terrorism, providing material support or resources to terrorist organizations, or harboring terrorists. Includes both domestic and international terrorism offenses.
Murder
Conviction for murder as defined under 18 USC 1111 (first or second degree) or equivalent state murder statutes. This includes murder committed during the commission of another felony (felony murder).
Crimes Involving Weapons of Mass Destruction
Any conviction related to the development, production, stockpiling, transfer, acquisition, retention, or use of chemical, biological, radiological, or nuclear weapons or materials.
Permanent Means Permanent
Interim Disqualifying Offenses
Interim offenses disqualify you only if the conviction occurred within the past 7 years OR you were released from incarceration within the past 5 years (whichever date is more recent). Once both time periods have passed, the offense no longer bars you. During the disqualification period, you can apply for a waiver:
Assault with intent to murder — includes attempted murder and assault with a deadly weapon with intent to kill under federal or state law.
Kidnapping or hostage taking — unlawful seizure, confinement, or detention of a person by force, including false imprisonment by force and ransom demands.
Rape or aggravated sexual abuse — sexual assault convictions under federal or state statutes.
Unlawful possession, use, sale, or manufacture of firearms or explosives — includes illegal possession, trafficking, and manufacturing of weapons or explosive devices.
Distribution, intent to distribute, or importation of controlled substances — drug trafficking and distribution convictions. Note: simple possession alone is not listed as a disqualifying offense, though it may affect other aspects of your CDL.
Extortion — obtaining property or services through coercion, threats of violence, or abuse of official position.
Arson — intentional and malicious destruction of property by fire or explosion.
Robbery — taking property from a person by force, threat of force, or intimidation.
Bribery — offering, giving, soliciting, or receiving anything of value to influence an official act, particularly involving public officials or transportation security.
Smuggling — illegal import, export, or transportation of goods, contraband, or persons across borders.
Immigration violations — fraud involving immigration documents, illegal reentry after deportation, or harboring illegal aliens.
RICO violations — racketeering, organized crime activity, and criminal enterprise convictions under the Racketeer Influenced and Corrupt Organizations Act.
Conspiracy or attempt — conspiracy or attempt to commit any of the above offenses carries the same disqualification as the completed offense.
The 7-Year Lookback Window
For interim disqualifying offenses, TSA applies a dual-window test. Both conditions must be met for the offense to no longer disqualify you:
| Condition | Window | Example |
|---|---|---|
| Conviction date | More than 7 years ago | Convicted Feb 2018, clear after Feb 2025 |
| Release from incarceration | More than 5 years ago | Released June 2020, clear after June 2025 |
| Both windows must have passed. In the example above, the applicant would be clear after June 2025 (the later of the two dates). | ||

How the FBI Fingerprint Background Check Works
The hazmat background check is fingerprint-based, not name-based. This is more accurate than name-based checks because it positively identifies you through biometric data, eliminating most false matches. However, it also means every fingerprinted arrest in your history will appear, even if:
Charges were dropped — the arrest may still appear on the FBI record even without a conviction. TSA should not count non-convictions as disqualifying, but incomplete records can cause delays.
Case was dismissed — dismissals should appear in the disposition, but some records lack updated disposition data, showing only the arrest and charge.
Record was expunged at the state level — state expungement orders do not always result in removal from the FBI database. Your fingerprints link to the federal record regardless of state action.
You can request your own FBI Identity History Summary at identity.fbi.gov for $18 to see exactly what TSA will find before you apply. This is strongly recommended if you have any arrest history.
Mental Capacity and Dishonesty in Application
Beyond criminal offenses, TSA can also deny a hazmat endorsement based on:
Adjudication of mental incapacity
If a court has found you mentally incompetent or has committed you involuntarily to a mental institution, this can be a disqualifying factor.
Dishonesty in the application
Providing false or misleading information on your hazmat endorsement application — including omitting criminal history — is itself a basis for denial. TSA will find the records through the FBI check, and dishonesty raises additional security concerns.
Never Omit Criminal History on Your Application
Waiver and Rehabilitation Process
If you are within the 7-year lookback window for an interim disqualifying offense, you can request a waiver from TSA. The waiver process evaluates whether you have been rehabilitated and no longer pose a transportation security threat. TSA considers:
Nature and seriousness of the offense — less serious offenses with mitigating circumstances have better waiver odds than violent crimes.
Time elapsed since the offense — more time since conviction and release strengthens your case, even within the lookback window.
Completion of court-ordered conditions — successful completion of probation, parole, restitution, community service, and any mandatory treatment programs.
Employment and stability — consistent employment record demonstrating responsible behavior and integration into the community.
Character references — letters from employers, community leaders, clergy, counselors, or parole officers attesting to your rehabilitation.
Education and training — vocational training, CDL school completion, and other educational achievements since the offense.
If your waiver is denied, you can request a hearing before a TSA Administrative Law Judge within 60 days. For more detail on the full appeal process, see our TWIC and hazmat appeal guide — the appeal process is identical for both credentials.
Check Your Eligibility Before Applying
Before investing $86.50 in the TSA background check fee (non-refundable) plus your state's DMV testing fee, verify your eligibility. The hazmat endorsement costs add up, and a denial means you lose the TSA fee entirely:
Request your FBI Identity History Summary — $18 at identity.fbi.gov. This shows your complete fingerprint-based criminal record as TSA will see it.
Compare against the lists above — check each conviction against both the permanent and interim lists. Calculate the 7-year and 5-year windows for interim offenses.
Verify record accuracy — if your FBI record shows incorrect information (charges that were dismissed, convictions belonging to someone else), address these through the FBI challenge process before applying.
Consult an attorney if uncertain — a transportation attorney can review your record and advise whether you are eligible, need a waiver, or should wait until the lookback window passes.
Overlap with TWIC Card Disqualifications
The hazmat endorsement and TWIC card disqualification lists are identical under 49 CFR Part 1572. Both credentials require the same TSA Security Threat Assessment. If you already hold a valid TWIC, your hazmat TSA check may be expedited or the fee reduced because you have already passed the same background check. Conversely, if you were denied a TWIC, expect the same outcome for hazmat — and vice versa.
Drivers who need both credentials for maximum flexibility (port access plus hazmat hauling) should apply for both simultaneously to save time. See our hazmat endorsement application guide for the complete step-by-step process.

Frequently Asked Questions
What crimes permanently disqualify you from hazmat?
Six categories of offenses permanently disqualify you from obtaining a hazmat endorsement with no waiver or time limit: espionage or conspiracy to commit espionage, sedition or seditious conspiracy, treason, terrorism or material support of terrorism, murder (first or second degree), and crimes involving weapons of mass destruction (chemical, biological, radiological, or nuclear). These permanent disqualifications are defined in 49 CFR 1572.103(a) and cannot be overturned through any appeal or waiver process.
Can a DUI prevent hazmat endorsement?
A single DUI conviction is not on the list of disqualifying offenses for hazmat endorsement under 49 CFR 1572.103. However, a DUI conviction can trigger a CDL disqualification under separate FMCSA rules (49 CFR Part 383), which would prevent you from holding any CDL endorsement. Additionally, if the DUI involved an illegal controlled substance rather than alcohol, it could fall under the interim disqualifying offense of unlawful possession or use of controlled substances, triggering the 7-year lookback period.
How far back does TSA check for hazmat?
TSA checks your entire criminal history through an FBI fingerprint-based background check. However, the disqualification rules distinguish between permanent offenses (lifetime bar, no time limit) and interim offenses (disqualifying only if the conviction occurred within the past 7 years or you were released from incarceration within the past 5 years, whichever is more recent). So while TSA sees your full record, older interim offenses outside the lookback window do not disqualify you.
Can I get a waiver for a disqualifying offense?
You can request a waiver only for interim disqualifying offenses, not permanent ones. The waiver process requires you to demonstrate rehabilitation through evidence such as stable employment, completed probation or parole, community involvement, education, and character references. TSA evaluates each waiver request individually, considering the nature of the offense, time elapsed, and your behavior since the conviction. Waivers are not guaranteed, but they are regularly granted when strong rehabilitation evidence is presented.
Does a hazmat disqualification also affect TWIC?
Yes. The hazmat endorsement and TWIC card use identical disqualification criteria under 49 CFR Part 1572. The same list of permanent and interim disqualifying offenses applies to both credentials. If you are disqualified from one, you are disqualified from the other. Conversely, if you successfully obtain a waiver for one credential, the same rehabilitation evidence can support your application for the other, though each is processed separately.
Does a felony automatically disqualify you from hazmat?
No. There is no blanket felony bar. TSA disqualifies you only if your conviction matches a specific offense named in 49 CFR 1572.103 — such as murder, terrorism, arson, robbery, drug distribution, or weapons offenses. Many felonies (for example, simple theft, fraud, or DUI) are not on either the permanent or interim list, so they do not disqualify you from a hazmat endorsement on their own.
How long does a hazmat disqualification last?
It depends on the offense type. Permanent disqualifying offenses (espionage, sedition, treason, terrorism, murder, and weapons of mass destruction crimes) bar you for life with no expiration. Interim offenses disqualify you only while you are inside the lookback window — convicted within the past 7 years or released from incarceration within the past 5 years, whichever is later. Once both windows pass, the interim offense no longer disqualifies you.
