IBC Spill Containment: How to Choose a Pallet, Hard Top, or Berm for Your Totes
Quick Answer
A single IBC tote needs secondary containment that holds at least the full volume of the tote: 275 gallons for a 275 gallon IBC, 330 gallons for a 330 gallon IBC. Indoors, a polyethylene IBC spill pallet like the UltraTech IBC Spill Pallet Plus handles most single totes. Outdoors, rain fills an open sump, so use a hard top, a pullover cover, or a roofed area. For two totes side by side, a twin IBC spill pallet or twin hard top covers both with one sump. If you need something portable or temporary, an IBC berm folds down when it is not in use.
How much containment does an IBC tote need?
Two federal rules drive most IBC containment decisions.
- EPA container storage, 40 CFR 264.175. For hazardous waste storage areas, the containment system must hold 10% of the total volume of all containers or the volume of the largest container, whichever is greater. For one 330 gallon tote, that is 330 gallons. For two 330 gallon totes, 10% of 660 is only 66 gallons, so the largest container rule still sets the minimum at 330 gallons.
- SPCC, 40 CFR 112.8(c)(2). Facilities with more than 1,320 gallons of aboveground oil storage (counting containers of 55 gallons or more) must give bulk storage containers secondary containment for the entire capacity of the largest single container, plus enough freeboard to hold precipitation. Most IBC totes of oil, fuel, or lubricant fall under this rule.
The short version: size the sump for your largest tote, and if it lives outside, leave room for rain or keep the rain out.
This is general information, not legal advice. State and local rules and your own SPCC plan can be stricter. Check with your environmental manager or local authority.
275 vs 330 gallon IBC totes
The two common IBC sizes share the same 40 by 48 inch footprint. The 330 gallon tote is simply taller. That matters for containment in two ways:
- Sump capacity. A pallet that only holds 275 gallons is not enough for a 330 gallon tote under the largest container rule. Check the sump capacity on the product data sheet before you order.
- Weight. A full 330 gallon tote of water weighs about 2,750 lbs plus the tote. Denser chemicals weigh more. Confirm the pallet's load rating covers your heaviest product.
If you are still choosing a tote, ask what you will store, how often you will refill or swap it, and whether it will sit indoors or out. Those answers drive the containment choice too.

IBC Spill Pallet Plus: the workhorse for a single tote
The IBC Spill Pallet Plus, Part #1157 (no drain) and Part #1158 (with drain) are the most common way to contain one tote indoors.
- 100% polyethylene with UV inhibitors, so it won't rust or corrode.
- Low 28 inch profile, which makes loading the tote easier.
- Forklift pockets on two sides. Don't move it with a full tote on top.
- 8,500 lb rating for uniformly distributed loads. If your tote sits on pedestal feet, UltraTech recommends steel plates at least 12 by 12 inches under each foot to spread the weight.
- UltraTech states it can hold an IBC of up to 365 gallons under 40 CFR 264.175.
- Add the Bucket Shelf, Part #1160 to catch drips at the valve while you dispense. Order it with the pallet and UltraTech installs a bulkhead fitting that drains the shelf into the sump.
Need it outside? Add the Pullover Cover, Part #1159 or step up to a hard top.
Standard IBC Spill Pallet: for heavier loads
The IBC Spill Pallet, Part #1057 (no drain) and Part #1058 (with drain) carry up to 16,000 lbs uniformly distributed and have a larger sump. UltraTech recommends this model over the Plus if you ever stack two full totes.
Prefer steel? The Ultra-Steel IBC Spill Pallet, Part #1184 is 14 gauge galvanized steel with 4 way forklift access and a 5,650 lb rating. The Twin model, Part #1183 holds two totes side by side.
IBC Hard Top: for totes that live outside
Rain is the biggest problem with outdoor IBC containment. An open sump that is half full of rainwater has lost half its capacity, and under SPCC you need room for precipitation anyway.
The IBC Hard Top, Steel Model, Part #1185 and Twin IBC Hard Top, Part #1186 solve that with a built in steel cover.
- Keeps rain out, so the sump stays empty and ready.
- Locks with a standard padlock.
- Steel construction stands up to heat and fire better than poly.
- Removable grating for inspection and cleanup.
Plan ahead: hard tops are built to order and ship in 8 to 10 weeks. If you are buying for a deadline, order early.
IBC Berm: portable and temporary
The IBC Berm, Part #0816 pairs a polyethylene inner pallet with a PVC outer berm. It sets up in about 15 minutes with no tools, and the sidewalls fold down so a forklift can drop the tote in. It is a good fit for job sites, temporary storage, or anywhere a permanent pallet is overkill. Check chemical compatibility for both materials before storing aggressive chemicals.
Storing drums too?
The same rules apply to 55 gallon drums. The Ultra-Steel Spill Pallet, 2 Drum, Part #1180 is 14 gauge galvanized steel rated to 2,575 lbs. For outdoor drum storage, the Hard Top P2 and Hard Top P4 keep rain out the same way the IBC hard tops do.
How to pick in 30 seconds
- One tote, indoors: IBC Spill Pallet Plus (1157 or 1158).
- One tote, outdoors: IBC Hard Top (1185), or a Spill Pallet Plus with the Pullover Cover (1159) if it is covered most of the time.
- Two totes: Twin IBC Hard Top (1186) outdoors, Ultra-Steel Twin IBC Spill Pallet (1183) indoors.
- Heavy product or stacked totes: Standard IBC Spill Pallet (1057 or 1058).
- Temporary or moving around: IBC Berm (0816).
- Need a drain to empty rainwater or spills: pick the "with drain" version.

Frequently Asked Questions
How much secondary containment does a 330 gallon IBC tote need?
At least 330 gallons. Under both 40 CFR 264.175 and SPCC, containment must hold the full volume of the largest container. Outdoors under SPCC, you also need freeboard for rain.
Can I store two IBC totes on one spill pallet?
Yes, if the pallet is rated for it. A twin IBC spill pallet or twin hard top holds two totes side by side with one sump sized for the largest tote. Don't stack two full totes on the IBC Spill Pallet Plus. UltraTech recommends the standard IBC Spill Pallet, rated to 16,000 lbs, for that.
Can an IBC spill pallet be used outdoors?
Yes, but rain is the issue. Rainwater in the sump takes away spill capacity. Use a pullover cover, put the pallet under a roof, or use an IBC hard top with a built in cover.
Can I move an IBC spill pallet with a full tote on it?
No. The pallets are forkliftable when empty, but UltraTech does not recommend moving them loaded.
What is the difference between an IBC spill pallet and an IBC hard top?
A spill pallet is an open sump with grating that the tote sits on. A hard top adds a lockable steel cover that keeps out rain and restricts access, which makes it the better choice for outdoor storage.
How long do IBC spill pallets take to ship?
IBC Spill Pallet Plus models are currently shipping in about 3 to 4 weeks. Hard tops are built to order and ship in 8 to 10 weeks. Call or email us and we'll confirm current lead time before you order.
