Transport could get easier for IBCs with hazmat residue
If you wish it were easier to ship your empty hazmat intermediate bulk containers (IBCs), your wish may be coming true. Prompted by industry requests, the Pipeline and Hazardous Materials Safety Administration (PHMSA) may add an exception for IBCs containing only residue of hazardous material (residue IBCs). The exemption would resemble the existing exception for residue in non-bulk packages.
Current exemption does not apply to IBCs
Under current hazmat rules, a package containing residue of a hazmat must be transported in the same manner as if it were full (173.29(a)). However, the rule provides an exception (in 173.29(c)) for certain non-bulk packages with residue materials covered by Table 2 of the placarding table.

The exception applies to non-bulk packaging containing only the residue of hazmat covered by Table 2 of 172.504 that is not a material poisonous by inhalation or its residue shipped under the subsidiary placarding provisions of 172.505. These non-bulk packages:
- Do not have to be included in determining whether the placarding requirements apply to your load; and
- Are not subject to the hazmat shipping paper requirements when collected and transported by a contract or private carrier for reconditioning, remanufacture, or reuse.
IBCs currently do not qualify for this exemption.
Proposed exemptions for IBCs with residue
Changes under consideration would apply to IBCs containing a residue (not more than 0.3 percent full) of materials from the following hazard classes/divisions:
- 3 (paints, acetone, gasoline, etc.);
- 4.1 (nitrocellulose, magnesium, etc.);
- 5.1 (ammonium nitrate, pool chemicals, etc.);
- 6.1 PG III (pesticides, methylene chloride, etc.);
- 8 (sulfuric acid, lye, etc.); or
- 9 (ammonium nitrate fertilizers, acetaldehyde ammonia, etc.).
These residue IBCs would be exempt from hazmat transport requirements for:
- Shipping papers, marking, labeling, and placarding; and
- Emergency Response Information (ERI). (Shipments not subject to shipping papers are not subject to ERI).
Petitioners suggest that costs would be lower if:
- Placarding is no longer required for a vehicle carrying residue IBCs, and
- A driver without a hazmat endorsement is allowed to operate the vehicle.
A recent advance notice of proposed rulemaking (HM-265A) seeks input on these changes, including parameters of an exception, current practices, and potential cost savings. Submit your comments by October 3, 2023, to participate in the process.
Periodic testing and placard requirements may also change
Other changes being considered for IBCs may:
- Extend the periodic retesting interval to up to five years for UN specification non-bulk packagings and IBCs to:
- Align with international standards that permit longer retest intervals, and
- Reflect the higher quality manufacturing practices now in place in the packaging industry.
- Revise the placard visibility requirements of 172.516 so that placards displayed on IBCs could be used to meet the visibility requirement.
Key to remember: Changes to the rules for transporting IBCs could save time and money for hazmat transporters. If you have experience in this area, submit your comments to help shape the amendments.
