FMCSR 173.30: No or Improper HM Loading by Shipper — Q&A

No, not usually. Across our 13 million inspection records, citations for 173.30 result in an out-of-service placement only 16.1% of the time. That's significantly lower than the 31.4% all-FMCSR average OOS rate. Of the 56 all-time citations for this code in our database, 9 resulted in OOS and 47 did not. You're more likely to receive a citation and warning than to be pulled from service, but the possibility exists if the hazmat loading violation poses an immediate safety risk.

Much less serious than most. Our data shows peer hazmat loading codes like 177.834A-HMC carry a 99.2% OOS rate and 177.834(a) carries 97.9%, meaning inspectors nearly always place trucks out of service for those violations. By contrast, 173.30's 16.1% OOS rate puts it at the lower end of severity. However, placarding violations like 177.817(a) hit 75.1% OOS, so 173.30 is genuinely one of the milder hazmat citations you can receive. The difference comes down to immediate danger: shipper loading errors may be correctable on-site, whereas active placarding failures are not.

First, document exactly what the inspector cited—whether it was improper stacking, inadequate blocking, or missing/damaged packaging. Second, contact your dispatcher and hazmat coordinator immediately to review the shipment and shipper records. Third, if the violation is correctible (loose load, improper documentation), photograph the correction. Fourth, request the inspection report and citation details to verify accuracy. Fifth, preserve all shipping papers and packaging information for your company's safety manager. If you believe the shipper was solely responsible and your actions complied with their paperwork, that detail matters for any follow-up.

No, it's quite rare. Our database shows only 56 all-time citations for 173.30, ranking it #1595 out of 3,036 FMCSR codes by volume. In the last 12 months, there was only 1 citation recorded nationwide, and 0 in the last 90 days. This suggests inspectors cite it selectively, typically when shipper negligence is obvious and documented. If you receive this citation, you're in a small group—which may actually be good news, as it indicates the violation was clear-cut rather than a borderline judgment call.

Over the last 180 days, our inspection records show Texas accounts for the only recorded enforcement of 173.30, with 1 citation and a 0.0% OOS rate in that instance. Historically, hazmat loading violations cluster in major freight hubs and port states, but 173.30 enforcement is sparse enough that patterns are difficult to establish across regions. If you're operating hazmat loads through high-volume terminals in Texas or other gateway states, remain vigilant about shipper compliance.

Citations remain on your safety record for 3 years under FMCSA rules. You can challenge it through the DataQs (FMCSA DataQuality System) process if you believe it was recorded incorrectly or if the violation did not actually occur. However, DataQs disputes work best for factual errors (wrong date, wrong code, duplicate entry) rather than subjective inspector judgment. If the loading defect was real, the stronger path is to work with your carrier's safety manager to demonstrate corrective action and shipper retraining, which can influence future scoring.

The distinction matters: 173.30 targets shipper conduct, not driver or carrier equipment failure. When an inspector finds a shipper's loading was improper, they may issue a citation to the carrier but leave the truck in service if the driver can immediately correct or remove the problem. Codes like 177.834(a)—which target active loading/unloading defects in progress—carry 97.9% OOS rates because inspectors halt operations on the spot. Similarly, 177.817(a) placarding violations hit 75.1% OOS because bad placarding is a safety-critical, non-negotiable violation. At 16.1%, 173.30 reflects inspector discretion to cite and allow continuation if the shipment can be made safe.

Yes and no. The citation goes to the carrier, not the individual driver, under FMCSA CSA scoring. However, you were present and responsible for verifying the load before departure. Your fleet's safety record reflects all hazmat violations tied to trucks you operated. The rarity of this citation (only 1 in the last 12 months) suggests it's cited only when shipper fault is glaring and documented. Your best protection is always inspecting the load against the shipping papers, identifying discrepancies, and refusing to haul if something looks unsafe. That protects both you and your carrier's score.
