What 172.202E means in plain language
When you're transporting hazardous materials, federal law requires shipping papers to include specific information about what you're carrying. A 172.202E citation means an inspector found that your hazmat shipping paper was missing one or more required elements: the proper shipping name, the hazard class, the UN/NA identification number, or the packing group.
This isn't a paperwork technicality. Shipping papers are the primary document that tells first responders, other drivers, and enforcement what's on your vehicle and how dangerous it is. An incomplete description means emergency personnel won't have the information they need if something goes wrong—and regulators won't know you were following the law.
The violation occurs at the point of transport. If your shipping paper is missing any of those four core pieces of information, you're in violation, even if you have other documents in the cab or know what's in the tank.
What our enforcement data actually shows
Across our 13 million+ inspection records, 172.202E is a low-volume citation. We've recorded 2 all-time citations for this code, with 2 citations in the last 12 months and 0 in the last 90 days. This ranks 172.202E at #2651 of 3,036 FMCSR codes by citation volume.
The out-of-service rate for 172.202E is 0.0%—meaning none of the 2 cited vehicles were placed out of service. This is notably lower than the all-FMCSR average OOS rate of 31.4%. However, the low citation count means this comparison has limited statistical weight. What the data does tell us is that when inspectors find incomplete hazmat descriptions, they typically issue a citation but don't immediately remove the vehicle from operation.
The enforcement pattern shows 1 citation in October 2025 and 1 in January 2026, suggesting this violation surfaces sporadically rather than in any seasonal cluster.
Who gets cited most
Our inspection records show Texas as the only state in the top enforcement list for 172.202E over the last 180 days, with 1 citation and a 0.0% OOS rate.
All-time, our data identifies two fleets with citations under this code: SEMA CONSTRUCTION INC (USDOT 443630) and AUTO LINEAS Y SERVICIOS HUINALA SA DE CV (USDOT 3003167), each with 1 citation. This does not imply a systemic compliance problem at either carrier—both are represented in our database by a single enforcement event.
How severe is this compared to similar codes
172.202E sits within the Hazardous Materials category alongside codes that carry much higher enforcement volume and out-of-service rates. For perspective:
- 177.834A-HMC (General loading/unloading hazmat) has 3,954 citations with a 99.2% OOS rate—meaning nearly all cited vehicles are pulled from service.
- 177.817(a) (Placarding violation) has 2,274 citations with a 75.1% OOS rate.
- 172.602(c)(1) (Maintenance/accessibility of Emergency Response information) has 1,464 citations but a 0.0% OOS rate, matching 172.202E's enforcement outcome rate.
The comparison shows that incomplete shipping paper descriptions are treated less severely in enforcement practice than loading/unloading violations or placarding failures, but similarly to failures in maintaining emergency response information.
How to avoid it
Before you accept a hazmat load, use this checklist:
- Verify the shipping paper has all four required elements: proper shipping name, hazard class, UN/NA identification number, and packing group. Don't load if any piece is missing or illegible.
- Cross-check the shipping paper against the bill of lading and any other transport documents. Discrepancies are a red flag that paperwork may be incomplete.
- Photograph or scan the shipping paper before departure. If an inspector questions it, you have a record of what you were given at pickup.
- Ask the shipper to correct any missing information in writing before you leave the facility. It takes five minutes then; it takes hours at roadside.
- Know your load. Even if the paper is complete, you should understand what hazard class you're carrying and where emergency information is located in your cab.
- Keep all hazmat documents in the same location and in the same order every trip. Inspectors look for organization as a sign of compliance awareness.
If you're already cited, the violation itself does not carry an out-of-service order in practice, but it does attract scrutiny. Document what happened, understand where the paperwork gap was, and work with your dispatcher or hazmat coordinator to ensure it doesn't happen again.
