The number of wall tile boxes in a container is set by weight, not by space. Divide the payload you can load by the weight of one box, allowing for pallets and packing, and you have the box count.
A loaded tile container never looks full. A 20 ft container typically reaches its payload limit, often around 26 to 28 tonnes depending on the shipping line and route, long before the boxes reach the roof. The reasons are explained in why a tile container cannot be filled to the roof.
The calculation
You need three numbers from the factory: the weight of one box, the weight of one pallet with its packing, and the boxes per pallet. Then work through these steps:
- Agree the usable payload with your freight forwarder for your line, route and destination roads.
- If loading on pallets, subtract the weight of the pallets, corner boards and wrap.
- Divide what is left by the weight of one box to get the maximum boxes.
- Round down to whole pallets, or to whole rows if loading loose.
- Multiply by the square metres per box to get the area per container.
A worked example
The figures here are only to show the arithmetic. Suppose a box of wall tiles weighs 16 kg, the agreed payload is 26,000 kg and the container is loaded loose. Dividing 26,000 by 16 gives 1,625 boxes. If each box covers about one square metre, the container holds about 1,600 square metres.
Now suppose the same tiles go on pallets, and the pallets and packing add 1,000 kg. The usable weight falls to 25,000 kg, and the box count to about 1,560. Pallets cost you some tiles, but make unloading faster and safer. The trade-off is covered in pallets versus loose loading for tiles.
Your real numbers depend on the size, thickness and body of each tile. Thicker and larger tiles weigh more per box, so fewer boxes fit. Always ask the factory for its packing list and loading plan for your exact sizes.
20 ft or 40 ft?
A 40 ft container has twice the space but not twice the payload. For heavy goods like tiles, its usable payload is often similar to a 20 ft box or only a little higher, and road limits at your end may cap it further. That is why most tile orders ship in 20 ft containers.
The full payload picture, including tare weights and road limits, is in the maximum payload for a tile container.
Mixed loads
When you mix sizes in one container, calculate each line separately and add the weights. Heavy floor tiles and lighter wall tiles can share a container well, but keep the weight evenly spread along the floor. The loading plan should show where each design sits.
Do not overload to squeeze in extra boxes. An overweight container can be refused at the port or fined on the road, and the cost of that will be yours.
