There is no single "toilets per 40HQ" number. The right calculation is simple on paper:
Usable container volume (m³) ÷ carton volume per toilet (m³) = units per container — then check the weight limit.
For typical ceramic one-piece toilets, a floor-loaded 40' high-cube container lands in the roughly 190–240 unit range depending on carton size and loading pattern. Two-piece suites pack denser because the bowl and tank ship in separate, lower cartons. Palletizing cuts the count. The exact figure always comes from the specific SKU's carton dimensions and the factory's loading plan — never from a generic catalog number.
Start with the container, not the toilet
A 40' high-cube (40HQ / 40HC) is the workhorse for sanitary-ware because ceramic loads are volume-bound, not weight-bound. Its interior is standardized:
| 40' High-Cube (HC) | Typical figure |
|---|---|
| Internal length | 12,032 mm |
| Internal width | 2,352 mm |
| Internal height | 2,700 mm |
| Door opening (W × H) | 2,340 × 2,597 mm |
| Internal volume | ≈ 76 m³ |
| Typical max payload | ≈ 26,540 kg |
Sources: Hapag-Lloyd lists the internal dimensions and door opening; FreightUtils lists the 76 m³ capacity and ≈26,540 kg payload.
In practice you do not load all 76 m³. Cartons do not fill every millimetre, and you lose space to bracing, corner posts and air gaps. A realistic usable figure is about 66–68 m³ for a floor-loaded ceramic load.
Calculate the carton, not the bowl
The toilet's catalog dimensions are the starting point, but the shipping unit is the carton — the bowl plus a foam/PE shell, corner protectors and an outer box. That packaging can add 50–90 mm per side on a one-piece toilet, so the carton volume is always meaningfully larger than the bowl volume.
Carton CBM is calculated as:
carton CBM = (length m) × (width m) × (height m)
Then:
units = usable container volume ÷ carton CBM
One-piece vs two-piece packing differs
One-piece and two-piece toilets do not pack the same way.
| Model | Type | Catalog unit dimensions (L × W × H) |
|---|---|---|
| T111001 | One-piece | 725 × 395 × 755 mm |
| T111003 | One-piece | 640 × 365 × 780 mm |
| T112003 | Two-piece suite | 655 × 385 × 920 mm |
A one-piece toilet is a single, tall, bulky carton. A two-piece suite ships the bowl and tank as separate, lower cartons, which stack denser and spread handling risk. This is one reason two-piece models are often cheaper to land per unit. For a fuller trade-off (freight, breakage, installation), read our one-piece vs two-piece guide.
A worked example (carton sizes are illustrative)
Because carton dimensions are confirmed per SKU in the quotation, treat the numbers below as an example of the method, not a catalog promise.
Take a compact one-piece toilet with a carton of 720 × 440 × 860 mm:
- Carton volume: 0.72 × 0.44 × 0.86 = 0.272 m³
- Units at 67 m³ usable: 67 ÷ 0.272 ≈ 246
- Realistic floor-loaded count after the load pattern: roughly 220–235
Weight check: if a cartoned one-piece toilet weighs around 40 kg, 230 units weigh ≈ 9.2 t — comfortably under the ≈26.5 t payload. Ceramic toilet loads are almost always volume-bound, so CBM is the constraint that matters.
Floor-loaded vs palletized
- Floor-loaded packs the most units and is standard for full containers of sanitary-ware, but unloading is manual and slower.
- Palletized speeds unloading and reduces handling damage, but pallets consume volume and height. A 40HC takes roughly 25 Euro pallets (1,200 × 800 mm) (source: BWS container specifications), and every pallet layer leaves air above it.
Most importers floor-load toilet containers and reserve palletizing for mixed or fragile loads.
Planning a mixed-SKU load
A 40HQ rarely carries only toilets. Dense ceramic pairs well with lighter lines — basins, faucets and accessories — so you fill the remaining CBM without hitting weight. The rule of thumb:
- Put the heaviest ceramic (toilets, one-piece suites) low and central.
- Fill voids with lighter, flat-pack items like two-piece suites, basins, mirrors and brassware.
- Have the factory produce a loading plan (carton count, CBM, gross weight, floor-loaded or palletized) before the container is booked.
Get the loading plan before you commit
Before placing a container order, ask for four numbers per SKU: carton dimensions, units per carton, gross weight per carton, and total CBM. With those, a loading plan is arithmetic. Without them, any "units per container" figure is a guess.
For OTOL models the carton dimensions and loading plan are confirmed for the selected SKUs and destination in the quotation. Ask Nicole for the loading plan and a mixed-SKU CBM breakdown on your target models.
