§ 03.5Products / Specialty & Composite
When HDPE
isn’t the answer,
steel usually is.
The standard composite IBC covers the overwhelming majority of liquid duties. The exceptions — aggressive solvents, high temperatures, pressure, vacuum, long-term outdoor storage, extreme reuse cycles — need a different container entirely. These are those containers.

§ 03.5.1Material selection
Pick the wall material first. Everything else follows.
Nine out of ten specialty enquiries are really a material question in disguise. Once the wall material is settled, capacity, fittings and format are straightforward.
| Material | Best for | Avoid for | Temp range | Typical reuse cycles |
|---|---|---|---|---|
| HDPE (standard composite) | Aqueous chemistry, surfactants, glycols, oils, fertiliser | Aromatic solvents, strong oxidisers, >140 °F | -20 to 140 °F | 6–14 |
| 316L stainless | Aggressive solvents, acids, food & pharma, steam cleaning | Chloride-rich brines at temperature | -40 to 400 °F | 100+ |
| 304 stainless | Food, beverage, mild chemistry, hot fills | Halogenated and strongly acidic media | -40 to 400 °F | 100+ |
| Carbon steel (lined) | Petroleum products, lubricants, bulk fuels | Water-based or corrosive media | -20 to 300 °F | 40+ |
| Fluorinated HDPE | Aromatic solvents, some hydrocarbons | Strong oxidisers | -20 to 140 °F | 4–9 |
| PP inner (31HZ2) | Specific acid and base chemistry | Low-temperature impact duty | 32 to 180 °F | 6–12 |
This table is a starting point for conversation, not a compatibility assessment. Final material selection always needs your product data — concentration, temperature, contact time and any trace components.
Stainless steel IBCs
The long-life answer. A 316L stainless IBC costs several times what a composite does and lasts well past a hundred cycles, which makes its per-trip economics and per-trip carbon better than almost anything else in this catalog. It is also steam-cleanable, which solves the food and pharma sanitation problem outright.
- Capacities from 120 to 550 gallons
- Pressure-rated and vacuum-rated variants available
- Jacketed and insulated options for temperature-controlled duty
- CIP spray-ball fittings for in-place cleaning
- Tri-clamp, DIN and buttress fitting configurations
- Reconditioned and new units both available
Collapsible & folding IBCs
Where return freight dominates the economics. A folding IBC collapses to roughly a quarter of its erected height, which turns a return trailer of 48 empties into a return trailer of nearly 200. For closed-loop programmes with long return legs this is often the decisive factor.
- Collapses to approximately 25% of erected height
- Up to 4× return-freight density versus rigid units
- Rigid composite or steel-framed variants
- Best suited to managed asset pools with controlled return
- Higher unit cost, lower lifetime freight cost
§ 03.5.2Capacities outside the standard pair
Smaller than 275, larger than 330.
The 275 and 330 gallon formats dominate because they fit a trailer and a forklift perfectly. When your process does not suit either, these are the alternatives.
| Capacity | Footprint | Height | Tare | Per trailer | Typical use |
|---|---|---|---|---|---|
| 120 gal / 454 L | 40" × 32" | 42" | 78 lb | 80 | Low-volume specialty chemistry |
| 180 gal / 681 L | 42" × 36" | 46" | 95 lb | 64 | Pilot batches, sampling programmes |
| 220 gal / 833 L | 45" × 38" | 48" | 108 lb | 52 | Legacy European footprints |
| 275 gal / 1,040 L | 48" × 40" | 53" | 125 lb | 48 | Industry standard |
| 330 gal / 1,250 L | 48" × 40" | 62" | 148 lb | 48 | Industry standard, taller |
| 350 gal / 1,325 L | 48" × 42" | 66" | 165 lb | 40 | High-density liquids |
| 450 gal / 1,703 L | 54" × 44" | 68" | 232 lb | 32 | Bulk water treatment |
| 550 gal / 2,082 L | 60" × 48" | 72" | 290 lb | 26 | Large-batch blending |
Formats above 350 gallons generally use steel pallets and reinforced cages, and are frequently steel-bodied rather than composite. Forklift and racking clearances should be checked before ordering.

Specialty stock is matched, not listed
We do not hold deep standing stock in specialty formats — the population is too varied. What we do is match your requirement against current availability, both ours and our reclaim network. Lead times run two to six weeks depending on material and format.

§ 03.5.3The carbon case for stainless
The most expensive tote can be the greenest one.
A 316L stainless IBC carries far more embodied carbon than a composite — around 1,900 lb CO₂e. Divided across a hundred-plus service lives, that is under 19 lb per trip. A composite tote on six lives spends 53.
- Roughly 19 lb CO₂e per trip across a full stainless service life
- Steam-cleanable, so no wash chemistry and far less water
- Fully recyclable as high-grade stainless at end of life
- Best suited to controlled, closed-loop return programmes
- Economics only work when you actually get the unit back
That last point is the catch. A stainless IBC that goes out and never returns is the worst environmental outcome in this entire catalog. If you cannot guarantee return, a composite unit is the responsible choice.
§ 03.5.4Specialty, questioned
What to settle before you buy.
My solvent attacks HDPE. Is fluorinated HDPE enough or do I need steel?
It depends on the solvent, the concentration and the contact time. Fluorination creates a barrier layer that handles many aromatics and some hydrocarbons well, but it degrades with repeated exposure and the barrier is not uniform across the bottle. For long contact times or repeated cycles, stainless is the durable answer. Send us the product data.
Can IBC totes hold pressure?
Standard composite IBCs cannot — the 31HA1 design type is explicitly non-pressurised. Pressure-rated stainless IBCs exist and we can source them, but they are a different class of vessel with their own inspection regime.
Are collapsible totes worth the premium?
Only if you are paying for return freight on empties over a long leg. Run the arithmetic: unit cost premium against four-to-one return density across your expected cycles. For short-haul or one-way flows, they are not.
Do you buy specialty units as well?
Actively — stainless IBCs in particular, which are always worth recovering. If you have stainless sitting idle, see we buy your totes; it is usually worth considerably more than people expect.
Send us the product data
Specialty selection is a conversation, not a catalog lookup.
Product, concentration, temperature, contact time, duty cycle and whether you get the unit back. With those six facts we can specify properly.
