Key takeaways
- A 40 ft high-cube is ~67 m³ / ~26–28 t — mixed loads hit weight first
- Heavy crates at the bottom, light goods on top; never stone on cabinets
- Each category has its own packing method; ask for the packing plan in writing
- No voids, strapped to the floor, desiccant for the voyage
- Get a loading plan and photos before the ship sails
1. What the container actually holds
A 40 ft high-cube has roughly 67 m³ of internal volume and a maximum payload around 26–28 tonnes. Those two numbers behave very differently depending on what you load:
- Tiles and stone are dense — a few pallets can add several tonnes. These loads are weight-limited: you run out of payload long before you run out of space.
- Sanitary ware is bulky and light — it fills volume fast without weighing much.
- Doors and windows are long and light — awkward to stack, easy to damage at the edges.
- Cabinetry ships flat-packed — dense in panels, but the finished boxes are easily crushed.
This mismatch is exactly why one container can carry a whole villa: the heavy categories use the payload and the bulky ones use the remaining space.
2. How each category is packed
| Category | Packing | Watch for |
|---|---|---|
| Tiles | Cartons on pallets, foam corners, edge boards | Humidity softening cartons; chipped corners |
| Stone & slabs | Wooden A-frames or crates, face to face | Faces scratching each other if not interleaved |
| Sanitary ware | Individual cartons in crates, corner blocks | Staining from other cargo; cracked rims |
| Doors & windows | Bundled frames with edge protection, standing | Bending if laid flat under load |
| Cabinetry | Flat-packed panels, strapped, labelled by unit | Crushing; keep them high, never underneath |
| Furniture & lighting | Cartons and crates, small items boxed inside | Voids that let crates slide |
3. Stacking rules
- Bottom: the heaviest, densest, most rigid crates — tiles, stone, crated sanitary ware.
- Middle: doors and window frames stood on edge, braced against the walls.
- Top: flat-packed cabinetry, furniture cartons, lighting.
- Never put stone or tiles on top of cabinetry or furniture — the point load crushes the box below.
- Fill the voids: an air gap lets the whole load move. Use airbags or dunnage.
- Lash to the floor rings at several points, not once at the door.
4. A worked example: a 12-room villa in one 40 ft container
This is the shape of a typical villa package, and roughly how it divides a single 40 ft high-cube:
- Tiles and stone — floors, bathrooms, terraces and stairs: the bulk of the payload, perhaps 60% of the weight.
- Sanitary ware and fittings — 12 bathrooms: bulky, uses a large share of the remaining volume.
- Doors and windows — frames stood on edge along both walls.
- Kitchen and wardrobes — flat-packed panels and boxes across the top.
- Lighting and finishing items — small cartons filling the gaps at the door end.
Whether that all fits in one container or needs a second depends on the ratio of heavy to bulky. A project with generous natural stone and little cabinetry will hit the weight limit early; a project heavy on sanitary ware but light on stone will hit the volume limit. The only reliable answer is a loading plan based on actual quantities and weights.
5. When one container is not enough
- The weight limit is reached with space still free — add bulky, light goods, or move stone to a second container.
- Fragile goods cannot be separated from heavy ones — split rather than risk a claim.
- Site phasing: sometimes two shipments on a schedule beat one large one.
- Small remainders: an LCL booking for the balance is often cheaper than a second container.
6. Moisture, and why it matters more than you think
A container is a sealed steel box on a long sea voyage. Day–night temperature swings cause condensation inside, which is what stains packaging, softens cartons and corrodes metal fittings. Practical controls:
- Desiccant bags distributed through the load, not just at the door.
- Stretch film and sealed cartons rather than open crates where possible.
- Ventilated crates for anything that can trap moisture.
- Poly film barrier against the container walls for moisture-sensitive cabinetry.
7. Ask for these before the ship sails
- A loading plan: what goes where, with weights
- Packing photos per category, and photos of the loaded container
- Packing list with carton, pallet and package counts per category
- Gross weight and total volume as loaded, for customs and insurance
These four items turn a shipment from a hope into an auditable process. Combined with an inspection before packing, they are the difference between a container that arrives intact and one that arrives with a claim attached.
Frequently asked questions
How much fits in a 40 ft high-cube container?
About 67 m³ of usable volume and a payload of roughly 26–28 tonnes. In practice a mixed building-material load runs out of weight before volume, because tiles and stone are dense.
What should go at the bottom of a mixed load?
Heavy, dense, crated goods — tiles, stone slabs, sanitary ware in crates. Then lighter goods on top. Doors, panels and cabinetry should never be underneath stone or tiles.
When should I ship two containers instead of one?
When the load exceeds the weight limit before it fills the volume, or when fragile and heavy goods cannot be separated. Two half-full containers are usually a larger waste than one optimised mixed load plus a small LCL for the remainder.
How do you stop goods moving in transit?
Palletised and strapped loads, no voids, airbags or dunnage in the gaps, lashing to the container floor rings, and desiccant to control humidity across long sea voyages.
