What 178.704 means in plain language
FMCSR 178.704 governs the packaging standards for hazardous materials that are transported in Intermediate Bulk Containers—commonly called IBCs. These are large, reusable transport vessels used to move liquids, powders, and other hazardous substances. The regulation requires that any IBC used to transport hazmat must meet specific design, construction, and performance standards established in the hazmat rules.
When you're cited for 178.704, it typically means an inspector found that the IBC itself—or how it was being used to contain hazardous material—did not meet those packaging standards. This could involve structural defects, improper labeling on the container itself, incompatibility between the container material and the hazmat inside, or failure to meet pressure or impact test requirements that IBCs are supposed to pass.
Unlike some hazmat violations, a 178.704 citation does not automatically result in an out-of-service order. This distinction matters for your operation and your record.
What our enforcement data actually shows
Across our 13 million+ inspection records, 178.704 is a rarely cited violation. Our database shows only 2 all-time citations for this code, with 2 citations occurring in the last 12 months and 0 in the last 90 days. Because of the low volume, this code ranks #2651 out of 3,036 FMCSR codes by citation frequency.
The out-of-service rate for 178.704 is 0.0%—meaning none of the 2 citations in our records resulted in a vehicle being placed out of service. This stands in sharp contrast to the all-FMCSR average out-of-service rate of 31.4%. The absence of OOS actions on 178.704 citations suggests that when inspectors find packaging issues under this code, they are typically cited as violations but the vehicle is permitted to continue operating, at least at the moment of inspection.
The rarity of this citation should not be interpreted as a reason to deprioritize IBC compliance. Rather, it indicates that most carriers and drivers are maintaining compliant packaging systems, or that defects are being caught and corrected before roadside inspection.
Who gets cited most
Our inspection records show that Louisiana accounts for the only state-level citations in the last 180 days, with 2 citations recorded and a 0.0% out-of-service rate in that state.
When we look at carriers in our all-time data, MAKO ENTERPRISES LLC (USDOT 4008820) appears with 2 citations for 178.704. This observation reflects only the citation history in our database and does not indicate a pattern of systemic non-compliance; it simply shows which carrier appears in the enforcement record for this specific code.
The limited geographic and carrier data underscores how infrequently this violation is cited. Most hazmat-hauling operations are successfully maintaining packaging standards.
How severe is this compared to similar codes
To understand where 178.704 sits in the hazmat enforcement landscape, consider its peer codes in the hazardous materials category.
General loading and unloading violations—such as 177.834A-HMC and 177.834(a)—are far more heavily cited, with 3,954 and 3,839 citations respectively, and carry extremely high out-of-service rates of 99.2% and 97.9%. Placarding violations, like 177.817(a), show 2,274 citations with a 75.1% OOS rate. By contrast, 178.704's 2 citations and 0.0% OOS rate indicate it is one of the least-enforced and least-severe packaging-related codes.
Even codes addressing damaged or deteriorated placards—such as 172.516(c)(6)—have 1,796 citations and a 1.6% OOS rate, which is still substantially higher than 178.704. This comparison shows that IBC packaging defects, as currently enforced, are treated as lower-severity violations than loading errors, placarding failures, or emergency response information violations.
How to avoid it
Prevent a 178.704 citation by establishing a pre-trip inspection routine focused on your IBC and its contents:
-
Inspect the IBC exterior before departure. Look for dents, cracks, corrosion, or structural damage that could compromise containment. If you spot damage, do not load or move the container. Report it to your dispatcher and the shipper immediately.
-
Verify container-to-hazmat compatibility. Confirm that the IBC material (steel, plastic, composite) is compatible with the hazmat it holds. Your bill of lading, shipping papers, and the shipper's documentation must all match. A steel IBC is not safe for all chemicals; a plastic one may fail with others.
-
Check seals, closures, and gaskets. Ensure that the IBC's top closure, any gaskets, and internal or external valve caps are in place, properly seated, and not damaged. Leaking seals are a common red flag for inspectors.
-
Confirm proper labeling and markings. The IBC itself must display hazmat warning labels, proper class labels, and any required markings (e.g., "This side up" arrows, test dates for pressure-tested containers). Faded, missing, or incorrect labels invite citations.
-
Know your vehicle type. Our inspection data shows citations on DELCO and DODGE vehicles. Ensure your specific vehicle is approved for the hazmat load you are carrying and that any IBC-securing equipment is properly maintained.
-
Document compliance. Keep records of IBC inspection and maintenance. If your fleet owns or regularly uses IBCs, establish a preventive maintenance schedule and document it. This protects you and your carrier during audits or follow-up inspections.
The low citation frequency for 178.704 suggests that diligent pre-trip inspection and shipper coordination are effective safeguards.
