The freight on a container of IBCs is paid per TEU, not per litre. Two fleets of the same capacity can differ by a full container's cost on the same PO because one was specified around the cube and the other around the brochure. Container loading is a geometry problem, and it starts at the drawing board.
Work from the door, not the volume
- Internal dimensions and door opening are the real spec. A container whose footprint divides cleanly into 2.30 m and 2.34 m internal widths wastes nothing; the 1,140 mm common IBC width exists because it walks through the door and tiles the floor.
- Standardize the base across the fleet. Mixed footprints leave residual slots that freight pays for. One base dimension across IBC, pallet and frame families recovers centimetres per row.
- Model both orientations and the sequence. Rotation freedom, forklift access mid-load and the unload order at the far end all change what "fits" means.
- Verify mass and distribution, not just count. Total payload, axle-line balance and securing requirements decide the load plan; stacked weight must be certified per structure, not inherited from the catalog.
The empty leg: folding changes the return trip
Pooling programs pay twice — outbound loaded and inbound empty. A foldable transit container that nests to a fraction of its height turns return-leg volume into recovered freight; but the savings must be compared honestly against the fold mechanism's durability (hinges, latches, welds) and the washing method between loads. Where return volume is high, the fold repays its mechanical complexity; where it is not, a stackable rigid design is the cheaper engineering.
Rated load is three numbers
Static stack load, dynamic handling load and rack load are separate test conditions with separate answers. A container that stacks loaded four high on warehouse floor may fail the same pattern on a two-tier rack with unsupported span. Specify your support geometry to the manufacturer and make them state each rating for that support condition.
Life-cycle cost closes the spreadsheet
Total cost of a container fleet = purchase + cycles × (handling + cleaning + repair) + return freight + write-offs, divided by expected service life. Stainless designs that run beyond ten years of reuse amortize into noise per cycle; the same litre delivered in single-trip packaging never stops costing. If you run the numbers this way, the buying conversation stops being about unit price — which is exactly how Japanese chemical buyers specified their IBC programs at 1,000+ units a year.
