Everything you need to know about IBC tote sizes, dimensions, and specifications. Find the right container for your application.
Intermediate Bulk Containers (IBCs) are standardized industrial containers designed for the transport and storage of bulk liquids, pastes, and granulated materials. While IBC tanks come in various configurations, two sizes dominate the market: the 275-gallon (1,000-liter) and the 330-gallon (1,250-liter) models. Understanding the differences between these sizes is critical for selecting the right container for your specific application, optimizing your storage space, and ensuring regulatory compliance.
This guide covers every dimension, weight specification, pallet configuration, and use case you need to make an informed purchasing decision. Whether you are buying new, used, or reconditioned IBC totes, size matters.
The 275-gallon IBC is the global standard and the most widely used size across all industries. It fits perfectly on a standard 40" x 48" pallet and is the default choice for most liquid storage and transport applications. This size is universally compatible with filling lines, racking systems, and transportation equipment.
The 330-gallon IBC provides approximately 20% more capacity than the standard 275-gallon model. It uses the same pallet footprint but is taller, making it ideal for applications where maximizing volume per container is more important than stacking height. This size is common in chemical manufacturing, agriculture, and industrial cleaning.
Side-by-side specifications for every standard IBC tote size.

Standard HDPE IBC tanks can be stacked 2 high when full, provided the cage is in good condition and the stacking lip is undamaged. The bottom container must be on a flat, level surface capable of supporting the combined weight (approximately 4,850 lbs for two full 275-gallon units).
Empty IBC tanks can be stacked 3 to 4 high, depending on cage condition. Always inspect the corner posts and top frame before stacking. Collapsed or bent cage tubes reduce stacking capacity and can create dangerous conditions in storage yards.
IBC tanks are available in three primary materials, each with distinct advantages.

Beyond the standard 275 and 330-gallon models, several other IBC sizes exist for specialized applications.
A compact IBC designed for smaller volumes and tighter spaces. Built on a standard pallet but shorter than its larger counterparts. Ideal for specialty chemicals, lab supplies, and small-batch manufacturing where the standard 275-gallon unit is too large.
A double-wide IBC on a 48" x 48" square pallet, offering nearly twice the capacity of the standard 275-gallon model. Used in high-volume chemical and water treatment operations where maximizing per-unit capacity reduces handling.
An intermediate size between the 110-gallon and 275-gallon options. Built on a standard pallet with moderate height. Commonly found in European supply chains and occasionally used in the US for specialty food ingredients and pharmaceutical intermediates.
Standard IBCs can be modified or ordered with specialty features for unique applications.
Equipped with electric heating blankets or steam jackets to maintain product temperature. Essential for viscous products like chocolate, wax, adhesives, and asphalt emulsions that solidify at ambient temperatures. Heating systems typically operate at 120-180 degrees F and are thermostatically controlled.
Wrapped in rigid foam or thermal blankets to slow temperature change. Used for temperature-sensitive products during transport and outdoor storage. Insulation can maintain product temperature within a target range for 24-48 hours depending on ambient conditions.
Features a conductive HDPE bottle and grounding cable to safely dissipate static electricity. Required for flammable liquids, solvents, and dust-generating powders where static discharge could cause ignition. Bottle resistance tested to less than 1 megaohm.
Standard natural (translucent) HDPE bottles degrade under UV exposure within 12-24 months. Black carbon-filled HDPE bottles extend outdoor UV life to 3-5 years. Also prevents light-sensitive product degradation and inhibits algae growth in water storage applications.
A modified fill opening with an integrated splash guard reduces spillage during top-filling operations. Common in agriculture and chemical blending where IBCs are filled from overhead lines or hoses that may shift during operation.
Custom discharge manifold with multiple valve outlets for dispensing to several lines simultaneously. Used in manufacturing facilities where a single IBC feeds multiple filling stations or dosing pumps. Available in 2, 3, or 4-port configurations.
Proper stacking maximizes warehouse space and transportation efficiency. Here is the detailed breakdown by condition and content status.
| Scenario | Max Stack Height | Combined Weight | Surface Requirement | Cage Condition |
|---|---|---|---|---|
| 275 gal Full (water) | 2 high | ~4,850 lbs | Flat, level, 2,500+ lb capacity | Grade A or B -- no damage |
| 330 gal Full (water) | 2 high | ~5,790 lbs | Flat, level, 3,000+ lb capacity | Grade A or B -- no damage |
| 275 gal Full (SG 1.4) | 2 high | ~6,550 lbs | Reinforced floor, 3,500+ lb capacity | Grade A only |
| 275 gal Empty | 3-4 high | ~390-520 lbs | Flat, level surface | All corner posts intact |
| 330 gal Empty | 3 high | ~435 lbs | Flat, level surface | All corner posts intact |
| During Transport | 2 high max | Varies by contents | Flatbed/dry van floor | Must be strapped and braced |
•Never stack IBCs with bent or collapsed corner posts -- this is the primary load-bearing structure.
•Ensure the stacking lip (top frame) seats fully into the pallet recess of the unit above.
•Do not mix 275 and 330-gallon IBCs in the same stack -- the height difference creates instability.
•In outdoor yards, account for wind loads on empty stacked IBCs by limiting stack height to 2 high.
•Always use ratchet straps or chains when stacking IBCs on transport vehicles.
•Check floor load ratings before stacking in warehouse environments -- two full 275-gallon IBCs exert approximately 300 PSI on the floor through the pallet footprint.
The filled weight of an IBC depends on the specific gravity (SG) of the contents. Water has an SG of 1.0. Heavier liquids like sulfuric acid or glycerin have higher SGs and will make the IBC heavier. Use this reference table to estimate the filled weight of your IBC for storage and transport planning.
| Product Example | Approx. SG | 275 gal Filled Weight | 330 gal Filled Weight |
|---|---|---|---|
| Water | 1.00 | ~2,425 lbs | ~2,895 lbs |
| Vegetable Oil | 0.92 | ~2,240 lbs | ~2,670 lbs |
| Ethanol (100%) | 0.79 | ~1,940 lbs | ~2,320 lbs |
| Maple Syrup | 1.33 | ~3,180 lbs | ~3,800 lbs |
| Glycerin | 1.26 | ~3,020 lbs | ~3,610 lbs |
| Phosphoric Acid (85%) | 1.69 | ~4,010 lbs | ~4,790 lbs |
| Sulfuric Acid (93%) | 1.83 | ~4,330 lbs | ~5,170 lbs |
| Sodium Hydroxide (50%) | 1.52 | ~3,620 lbs | ~4,325 lbs |
Formula: Filled Weight = Empty Weight + (Capacity in gallons x 8.34 lbs/gal x Specific Gravity)
Example (275 gal with SG 1.0 water): 130 lbs + (275 x 8.34 x 1.0) = 130 + 2,294 = ~2,424 lbs
Example (330 gal with SG 1.33 syrup): 145 lbs + (330 x 8.34 x 1.33) = 145 + 3,660 = ~3,805 lbs
Always check your IBC's UN marking for the maximum rated specific gravity. Standard composite IBCs are rated up to SG 1.4. Heavier liquids may require specially rated containers. Exceeding the rated SG voids the UN certification and creates a serious safety risk.
