Regulations change, and specific requirements vary by jurisdiction, material class, and application. Always consult the applicable regulatory authority (DOT, FDA, EPA, or your state agency) or a qualified compliance professional for binding guidance on your specific situation.
UN Certification Overview
The United Nations (UN) performance packaging system establishes international standards for containers used to transport dangerous (hazardous) goods. IBC totes that are intended for hazardous material transport must be designed, tested, and certified according to these UN standards before they can legally be used for that purpose.
UN certification involves subjecting the IBC to a series of rigorous performance tests, including:
- Hydraulic pressure test — the tote is pressurized with water to verify structural integrity and leak-tightness
- Drop test — the tote is filled to maximum capacity and dropped from a specified height to simulate handling impacts
- Stacking test — weight is placed on top of the tote for a sustained period to verify it can support loads during stacked storage or transport
- Bottom lift test — the tote is lifted by its base to verify the pallet can support the full weight during forklift operations
- Vibration test — simulates the vibrations experienced during over-the-road transport
Only manufacturers with approved facilities and testing programs can certify IBC totes to UN standards. The certification is stamped or plated directly onto the tote's cage, creating a permanent, verifiable record.
Key point: UN certification is required only for transporting hazardous materials. Non-hazardous liquids (water, food products, non-regulated chemicals) can legally be stored and transported in IBC totes without UN certification, though many buyers still prefer certified totes for the quality assurance they represent.
31HA1 and 31HH1 Markings Explained
Every UN-certified IBC tote carries a marking code that tells you exactly what the tote is designed for. The two most common codes you will encounter on composite/rigid IBC totes are 31HA1 and 31HH1. Here is how to read them:
Decoding the UN Marking Code
| Code Element | Meaning | Examples |
|---|---|---|
| 31 | Container type: Rigid IBC for liquids | 31 = rigid IBC (as opposed to flexible IBCs like bags) |
| H | Material of construction: Plastic | H = plastic. A = steel. B = aluminum. N = metal other than steel/aluminum |
| A or H (second letter) | IBC sub-type: A = rigid plastic IBC with structural frame. H = composite IBC (plastic inner receptacle in an outer casing) | HA = rigid plastic with frame (most common). HH = composite design |
| 1 | Closed-top design (sealed for liquid transport) | 1 = closed top for liquids. 2 = open top for solids |

Packing Groups Explained
The packing group designation determines what hazard level the tote is approved to carry:
Approved for Packing Groups I, II, and III. The most stringent certification — passed the toughest tests. Required for the most dangerous materials.
Approved for Packing Groups II and III. The most common rating for IBC totes. Suitable for most regulated chemicals, solvents, and corrosives.
Approved for Packing Group III only. The least stringent certification. Suitable for materials that present minor hazard during transport.
DOT Hazardous Materials Transportation Rules
The U.S. Department of Transportation (DOT) regulates the transportation of hazardous materials under Title 49 of the Code of Federal Regulations (49 CFR). If you are shipping or transporting hazardous materials in IBC totes, you must comply with these requirements:
Container Certification
- •The IBC tote must bear a valid UN marking (not expired) appropriate for the material being transported
- •The tote's packing group rating (X, Y, or Z) must be equal to or higher than the packing group of the material
- •Rigid IBC totes (31HA1) must not exceed 5 years from the date of manufacture for hazmat transport unless they have been inspected and recertified (2.5-year inspection)
- •Composite IBC totes (31HH1) follow the same 5-year rule
Labeling and Placarding
- •Each IBC tote must display the proper DOT shipping name and UN number of the hazardous material
- •Appropriate hazard class labels (flammable, corrosive, toxic, etc.) must be affixed to at least two opposing sides of the tote
- •The vehicle carrying the totes must display DOT placards corresponding to the hazard class and quantity being transported
Documentation
- •A Shipping Paper (Bill of Lading or Dangerous Goods Declaration) must accompany every shipment of hazardous materials
- •The document must list the proper shipping name, hazard class, UN number, packing group, and total quantity for each hazardous material
- •Emergency response information must be immediately available to the driver
Training Requirements
- •Anyone who handles, packages, or transports hazardous materials must receive DOT hazmat training
- •Training must be completed within 90 days of employment and recertified every 3 years
- •Training records must be maintained by the employer for the duration of employment plus 3 years
Compatibility
- •The hazardous material must be compatible with the IBC tote's construction materials (HDPE, gasket material, valve material)
- •Certain materials require specific liner types, fluorinated bottles, or specialized gasket compounds
- •The material's specific gravity must not exceed the maximum gross weight divided by the tote's water capacity
Non-Hazmat Transport: If you are transporting non-hazardous materials (water, food products, non-regulated chemicals, etc.), DOT hazmat regulations do not apply. However, your IBC totes must still be in safe, functional condition, and loads must be properly secured to prevent shifting during transport per FMCSA cargo securement rules (49 CFR Part 393).
Food-Grade Requirements (FDA)
The U.S. Food and Drug Administration (FDA) regulates containers that come into contact with food and beverages under 21 CFR (Code of Federal Regulations). For IBC totes used in food, beverage, or pharmaceutical applications, the following requirements apply:
Material Compliance
The HDPE plastic used in the tote's bottle must comply with FDA regulations for food-contact substances (21 CFR 177.1520 for polyethylene). The plastic must not leach harmful substances into the food product under the intended conditions of use (temperature, duration, pH).
Manufacturing Standards
Food-grade IBC totes must be manufactured in facilities that follow Good Manufacturing Practices (GMP). This includes clean production environments, quality control testing, and documentation of materials and processes. Not all IBC manufacturers produce food-grade totes.
Chain of Custody
For used IBC totes to retain food-grade status, they must have a documented chain of custody showing they have only ever contained food-safe products. A tote that held industrial chemicals — even once — is permanently disqualified from food-grade use, regardless of how thoroughly it is cleaned.
Cleaning and Sanitization
Used food-grade IBC totes must be cleaned and sanitized according to documented procedures before reuse with food products. At minimum, this involves triple-rinsing with potable water, sanitizing with an FDA-approved sanitizer, and final rinsing. Our reconditioning process meets these standards.
Valve and Gasket Materials
All components that contact the food product — including valves, gaskets, and lid seals — must also be made from FDA-compliant materials. When replacing these components, ensure the replacement parts are specifically rated for food contact.
Traceability
Food-grade applications often require batch traceability. This means the tote must be labeled with the product name, batch number, fill date, and origin. Some industries (dairy, juice, wine) have additional labeling requirements specific to their regulatory frameworks.
Fort Wayne IBC Recycling Food-Grade Policy: We maintain a separate inventory of verified food-grade IBC totes with documented prior contents and cleaning history. Every food-grade tote we sell includes a documentation packet showing its chain of custody. If you need food-grade totes, contact us to discuss your specific requirements.
State and Federal Environmental Regulations
Beyond DOT and FDA, several other regulatory frameworks may apply depending on how you use IBC totes:
EPA — Spill Prevention and Containment
The Environmental Protection Agency's Spill Prevention, Control, and Countermeasure (SPCC) rule applies to facilities that store more than 1,320 gallons of oil (or 660 gallons in a single container) above ground. If your IBC totes collectively exceed these thresholds with oil products, you may need an SPCC plan. This includes secondary containment (spill pallets or berms) capable of holding 110% of the largest container's volume.
OSHA — Workplace Safety
The Occupational Safety and Health Administration requires proper labeling of chemical containers in the workplace under the Hazard Communication Standard (HCS / GHS). IBC totes containing chemicals must display GHS-compliant labels with hazard pictograms, signal words, and safety data sheet (SDS) references. Employers must also ensure workers have access to SDS documents for every chemical stored in IBC totes on-site.
Indiana State Regulations
The Indiana Department of Environmental Management (IDEM) enforces state-level environmental regulations that may affect IBC tote storage and handling. This includes waste oil storage regulations, hazardous waste generator requirements, and stormwater management rules. Indiana also follows the Universal Waste Rule, which may apply to certain materials stored in IBC totes. Agricultural use of IBC totes (pesticide storage, fertilizer handling) is subject to Indiana State Chemist Office regulations.
Rainwater Harvesting Laws
Indiana does not prohibit or restrict residential rainwater harvesting, making IBC totes a popular choice for this application. However, some municipal codes may have specific requirements about container placement, mosquito prevention (covered openings), and setback distances from property lines. Always check your local building codes and HOA regulations before installing an outdoor IBC tote.
Fire Code
The International Fire Code (IFC), adopted by most Indiana jurisdictions, has specific requirements for flammable and combustible liquid storage. IBC totes used to store flammable liquids may be subject to quantity limitations, fire separation distances, and ventilation requirements depending on the flash point and volume. Consult your local fire marshal for specific requirements.
RCRA — Hazardous Waste Containers
Under the Resource Conservation and Recovery Act (RCRA), IBC totes that previously held hazardous waste may themselves be classified as hazardous waste containers. To declassify, the tote must be triple-rinsed with a solvent capable of removing the residue, and the rinse water must be managed as hazardous waste. Documentation of the triple-rinse process should be maintained. Many facilities choose to work with a licensed reconditioner (like Fort Wayne IBC Recycling) to handle this process properly.
Certification Expiration and Reuse Rules
Understanding when an IBC tote's certifications expire — and what that means for your operations — is critical for staying compliant:
5-Year UN Certification Expiration
Rigid IBC totes (31HA1) and composite IBC totes (31HH1) carry a UN certification that is valid for 5 years from the date of manufacture stamped on the data plate. After 5 years, the tote can no longer be used to transport regulated hazardous materials unless it passes a retest and recertification inspection. However, expired UN certification does not affect the tote's use for non-regulated materials — it can still legally store and transport water, food products (if food-grade), agricultural liquids, and non-regulated chemicals indefinitely.
2.5-Year Intermediate Inspection
DOT regulations require a periodic inspection of IBC totes at intervals not exceeding 2.5 years from the date of manufacture. This inspection verifies that the tote remains in suitable condition for hazmat transport. The inspection must be performed by a qualified person and documented with the inspection date marked on the tote. Failure to complete the 2.5-year inspection renders the tote non-compliant for hazmat transport, even if it is within the 5-year certification window.
Reconditioning and Recertification
IBC totes can be reconditioned (cleaned, repaired, rebottled) and recertified for hazmat use. When a tote is recertified after reconditioning, a new marking is applied showing the reconditioner's identification and the recertification date. This effectively resets the certification clock for another 5 years. Not all reconditioners are authorized to recertify — the facility must be registered with DOT/PHMSA.
Reuse for Non-Regulated Materials
There is no expiration date for using IBC totes with non-regulated, non-hazardous materials. As long as the tote is structurally sound, leak-free, and appropriate for the contents, it can be reused indefinitely. This is why Grade B and Grade C totes with expired UN certifications remain valuable and fully functional for agriculture, water storage, DIY projects, and general industrial use.

After years of working with businesses across Indiana and the Midwest, we see the same compliance errors again and again. These mistakes can result in fines, failed audits, liability exposure, and even criminal penalties for serious violations. Here are the top mistakes and how to avoid them.
Using Expired UN-Certified Totes for Hazmat
Continuing to transport hazardous materials in IBC totes more than 5 years past the manufacture date without recertification.
DOT violation. Fines up to $75,000 per violation. Potential criminal liability if a spill occurs during transport.
Check the manufacture date on every tote's data plate before loading hazmat. Recertify or replace totes approaching the 5-year mark. Set calendar reminders for your fleet.
Skipping the 2.5-Year Inspection
Many operators know about the 5-year expiration but overlook the mandatory 2.5-year intermediate inspection required for hazmat totes.
The tote is technically non-compliant for hazmat transport, even if it is within the 5-year window. Inspectors treat this the same as an expired certification.
Schedule 2.5-year inspections proactively. Our reconditioning service includes the required inspection and documentation.
Calling a Tote 'Food-Grade' Without Documentation
Labeling or advertising a tote as food-grade based solely on its appearance or the fact that the HDPE is 'food-safe plastic,' without a documented chain of custody.
FDA enforcement action, product recall, consumer injury liability. A tote is not food-grade unless its entire history is documented.
Maintain a complete chain-of-custody record for every food-grade tote: manufacturer documentation, prior contents, cleaning certificates, and handling records.
No Secondary Containment for Oil Storage
Storing IBC totes of oil products above ground without secondary containment (spill pallets or berms) when total oil storage exceeds 1,320 gallons.
EPA SPCC violation. Fines start at $25,000 per day of violation. If a spill reaches waterways, penalties escalate dramatically.
Install secondary containment capable of holding 110% of the largest container's volume. If you have 5 or more IBC totes of oil products, you almost certainly need an SPCC plan.
Missing OSHA GHS Labels on Chemical Totes
Storing chemicals in IBC totes in the workplace without GHS-compliant hazard labels — or with outdated, damaged, or illegible labels.
OSHA Hazard Communication Standard violation. Fines range from $15,625 (serious) to $156,259 (willful/repeat). Worker injury liability.
Apply GHS-compliant labels to every chemical tote immediately upon receipt. Replace any label that becomes damaged or illegible. Keep SDS documents accessible within the work area.
Mixing Food-Grade and Non-Food Totes
Failing to physically segregate food-grade IBC totes from industrial/chemical totes in storage. Cross-contamination can occur from vapor transfer, accidental switching, or contact.
Loss of food-grade certification for the entire inventory. Product contamination risk. FDA enforcement.
Store food-grade totes in a separate, clearly marked area. Use distinct-colored tags or labels. Never store food-grade totes adjacent to chemical totes.

Regulatory Updates: 2024-2025
Regulations affecting IBC tote storage, transport, and reuse continue to evolve. Here are the most relevant recent changes and proposed rules that IBC tote operators should be aware of.
PHMSA Harmonization Updates (2024)
In EffectThe Pipeline and Hazardous Materials Safety Administration (PHMSA) continued harmonizing U.S. hazmat transportation rules with international UN standards through a series of final rules published in 2024. Key changes include updated compatibility tables for certain chemical classes, revised marking requirements for reconditioned IBCs, and clarified inspection documentation standards. These changes primarily affect businesses that ship hazardous materials via IBC totes across state lines.
EPA SPCC Rule Clarifications
OngoingThe EPA has issued additional guidance clarifying how the Spill Prevention, Control, and Countermeasure (SPCC) rule applies to facilities using IBC totes for oil storage. The guidance confirms that IBC totes count toward the 1,320-gallon aggregate threshold and that each tote location requires documented containment measures. Facilities that have added IBC totes since their last SPCC plan review should update their plans accordingly.
FDA Food Safety Modernization Act (FSMA) Enforcement
Enforcement IncreasingFDA enforcement of FSMA rules related to food-contact containers has intensified, with increased focus on documentation of supply chain controls for reused containers including IBC totes. Businesses using IBC totes for food or beverage contact should ensure their supplier provides FSMA-compliant documentation including supplier verification records and cleaning validation certificates.
Indiana IDEM Waste Classification Updates
In EffectThe Indiana Department of Environmental Management (IDEM) updated its waste classification guidelines affecting how used IBC totes that contained certain chemicals are categorized for disposal. Totes that held listed hazardous wastes now require documented triple-rinse decontamination before they can be reclassified as non-hazardous for resale or reuse. This affects operations that generate used totes from chemical processes.
OSHA GHS Label Update (HazCom 2024)
Implementation PeriodOSHA finalized updates to its Hazard Communication Standard aligning with the seventh revision of the Globally Harmonized System (GHS Rev. 7). Changes include new and revised hazard categories, updated precautionary statements, and modified label elements for certain chemical classes. Employers must update GHS labels on chemical IBC totes to reflect these changes. The implementation includes a transition period, but updating labels proactively is recommended.
