IBC Tote Technical Specifications
Authoritative reference data for intermediate bulk containers -- dimensions, materials, valve configurations, regulatory markings, and performance ratings for every major IBC type.
Standard IBC Dimensions by Capacity
IBC totes are manufactured in several standard capacities. The 275-gallon (1,040-liter) composite IBC is by far the most common in North American markets. Dimensions below are nominal and may vary by +/- 0.5 inches between manufacturers.
| Capacity | Length (in) | Width (in) | Height (in) | Tare Weight (lbs) | Max Gross (lbs) |
|---|---|---|---|---|---|
| 110 gal (420 L) | 39 | 39 | 37 | 90-110 | 1,540 |
| 180 gal (680 L) | 46 | 40 | 42 | 100-120 | 1,870 |
| 275 gal (1,040 L) | 48 | 40 | 46 | 120-145 | 2,500 |
| 330 gal (1,250 L) | 48 | 40 | 53 | 130-160 | 2,980 |
| 550 gal (2,082 L) | 48 | 48 | 62 | 200-250 | 4,850 |
* Heights include pallet. Tare weight varies based on pallet material (wood, plastic, steel). Max gross weight assumes water at 8.34 lbs/gal. Denser liquids reduce the usable fill volume.
IBC Construction Materials

Valve Types and Sizes
The discharge valve is the most frequently replaced component on an IBC tote. Understanding valve types ensures compatibility with your filling and dispensing equipment.
| Valve Type | Size | Thread Standard | Material | Best For |
|---|---|---|---|---|
| Butterfly Valve | 2" (50 mm) | NPS 2" buttress | Polypropylene body, EPDM gasket | General-purpose liquids, water, mild chemicals |
| Ball Valve | 2" (50 mm) | NPS 2" buttress | PP or PVDF body, PTFE seat | Viscous liquids, precise flow control, chemical applications |
| Cam Lock Valve | 2" (50 mm) | Cam & groove adapter | Aluminum, stainless steel, or polypropylene | Quick-connect systems, frequent coupling/uncoupling |
| S-Series Coarse Thread | 3" (80 mm) | S100x8 or S75x6 | HDPE cap, PP adapter | European-origin IBCs, gravity-feed systems |
| Sanitary / Tri-Clamp | 1.5" - 3" | Tri-Clamp ferrule | 316L stainless steel | Food, beverage, pharmaceutical, biotech |
| Piston / Diaphragm | 2" (50 mm) | NPS 2" buttress | PP body, EPDM or Viton diaphragm | Aggressive chemicals, zero-drip requirements |
Gasket Compatibility: Always match the gasket material to your product. EPDM is the standard for water-based liquids. Viton (FKM) is required for oils, fuels, and many solvents. PTFE-encapsulated gaskets provide the broadest chemical compatibility at a higher cost. See our IBC Accessories page for replacement parts.

DOT Requirements for IBC Transport
The U.S. Department of Transportation regulates the use of IBCs for transporting hazardous materials under 49 CFR Parts 171-180. Key requirements include:
Initial Qualification Testing (49 CFR 178.810)
Every IBC design must pass a battery of tests before it can be manufactured: drop test (0.8 m for PG III, 1.8 m for PG I), top-lift test (2x max gross weight for 5 minutes), stacking test (1.8x max gross weight for 24 hours), hydrostatic test, and a leakproofness test at 20 kPa for 10 minutes.
Periodic Retest and Inspection (49 CFR 180.352)
Metal and rigid plastic IBCs must be visually inspected every 2.5 years and pressure-tested every 5 years. Composite IBCs (31HA1) with HDPE bottles must not be used for hazardous materials transport after 5 years from the date of manufacture of the inner receptacle.
Marking and Labeling (49 CFR 172.300)
IBCs carrying hazardous materials must display the proper shipping name, UN identification number, and hazard class labels. Placards are required on transport vehicles carrying over 1,000 lbs of the same hazard class.
Reconditioning Requirements (49 CFR 180.350)
Reconditioned IBCs must be inspected and tested by a registered reconditioner. The reconditioner's UN marking must be added adjacent to the original manufacturer's marking, along with the reconditioning date.
Compliance Warning: Using an expired or non-certified IBC for hazardous material transport can result in DOT fines of up to $79,976 per violation (as of 2024). If you are unsure about the regulatory status of your IBCs, consult with a qualified hazmat compliance specialist or contact our team for guidance.
Temperature Ratings and Limitations
Temperature tolerance varies significantly by IBC material and valve/gasket components. Operating outside rated ranges can cause structural failure, leaks, or product contamination.
| IBC Type | Min Temp | Max Temp (Continuous) | Max Temp (Short-term) | Notes |
|---|---|---|---|---|
| HDPE Composite | -40 F (-40 C) | 140 F (60 C) | 160 F (71 C) | HDPE softens above 160 F. Filling above 140 F causes thermal expansion that may exceed cage clearance. |
| Fluorinated HDPE | -40 F (-40 C) | 150 F (65 C) | 170 F (77 C) | Fluorination layer improves permeation resistance but does not significantly raise temperature rating. |
| 304 Stainless Steel | -320 F (-196 C) | 800 F (427 C) | 1,500 F (816 C) | Gasket and valve materials are the limiting factor, not the shell. Standard EPDM gaskets max at 250 F. |
| 316L Stainless Steel | -320 F (-196 C) | 800 F (427 C) | 1,500 F (816 C) | Preferred for high-temperature corrosive environments. Superior resistance to pitting and crevice corrosion. |
| Carbon Steel (epoxy-lined) | -20 F (-29 C) | 300 F (149 C) | 350 F (177 C) | Lining type determines actual max. Phenolic linings tolerate higher temps than epoxy. |
Outdoor Storage Note: HDPE IBCs stored outdoors in direct sunlight can experience surface temperatures 30-40 F above ambient. In southern states during summer, this means the product inside can reach 140 F or higher, approaching the rated limit. Use shade structures or insulated blankets for sensitive products.

Disclaimer: This table is provided as a general guideline. Chemical compatibility is affected by concentration, temperature, exposure duration, and the presence of other chemicals. Always conduct your own compatibility testing or consult the chemical manufacturer's recommendations before committing to a container material. When in doubt, request a sample coupon test from the IBC manufacturer.
Stacking and Loading Specifications
Proper stacking and loading are critical for warehouse safety, transport compliance, and maximizing storage density. These specifications reflect industry standards and common regulatory requirements.
Stacking Specifications
Truck Loading Reference
Forklift Handling: Always use forklifts rated for the loaded weight of the IBC. A standard 275-gallon IBC filled with water weighs approximately 2,400-2,500 lbs. Use fork tines at least 42 inches long to ensure full pallet engagement. Enter the pallet from the designated fork entry side only -- most IBC pallets are 2-way entry, not 4-way.
