How to Renew a Hazmat Endorsement (2026)
Renew Hazmat every 5 years with a new TSA background check — your ELDT training is permanent and is never retaken.
The renewal flow at a glance
Renewing a Hazmat endorsement is a security step, not a training step. Hazmat endorsements renew every 5 years; new TSA background check required, ELDT NOT repeated. The cycle is: apply to renew before expiry, complete a new TSA threat assessment (fingerprinting via IDEMIA Universal Enroll), wait for clearance, and let your state reissue the endorsement. For why the training is excluded from this loop, see Does ELDT Expire? and How Long Is a Hazmat Endorsement Good For?.
The single most important habit is starting early. TSA clearance typically takes 30–45 days, so a driver who waits until the endorsement is days from expiring risks a coverage gap where they cannot legally haul hazardous materials. Begin the renewal 60–90 days ahead.
What the TSA background check costs and covers
The TSA Hazmat threat assessment is the renewal's main cost: about $86.50 through IDEMIA Universal Enroll, or roughly $41 if you hold a valid TWIC (Transportation Worker Identification Credential), since the screenings overlap. You provide fingerprints and identity documents at an enrollment center, and TSA runs a criminal-history and security check.
This is the same type of check you passed when you first obtained the endorsement — it simply re-verifies you still qualify under federal security rules. Your state DMV may add its own renewal fee on top. None of this involves training: you do not repeat Hazmat ELDT to renew.
Why renewal never includes ELDT
ELDT is a one-time federal requirement. Once your FMCSA-approved provider submits your Hazmat ELDT completion to the Training Provider Registry, that record is permanent — it never expires. Renewal re-runs the TSA security screening, not the training, so there is nothing to retake. The main-domain How to Get a Hazmat Endorsement page and ELDT training requirements page confirm the federal framework.
If you are adding Hazmat for the very first time rather than renewing, that is a different process — you DO complete Hazmat ELDT once. See our How to Add Hazmat to an Existing CDL guide. Each DLA Hazmat course is $20 and is theory-only.

Tanker and Doubles/Triples need no ELDT at all
There is no ELDT requirement for the Tanker (N) or the Doubles/Triples (T) endorsement. The federal rule covers Class A, Class B, the B-to-A upgrade, and Hazmat, Passenger and School Bus — and nothing else. Both are knowledge-test only at your state DMV. If you want to study for the Tanker test, Tanker Test Prep is $15; if you need the Hazmat ELDT alongside it, Hazmat & Tanker Complete is $45.
