Whereas stackable pallets can have other freight stacked on top of them during transit, non-stackable pallets cannot. When your shipment is quoted you will be asked to confirm whether your pallet is stackable, as this will affect the price provided.
The short answer is ‘yes’. But limits depend on factors such as the service required or the origin and destination of shipment. For example, if you are shipping via air freight, 160cm is the maximum height that a passenger aircraft can accommodate. If your shipment is larger, then a cargo aircraft would be a better (but more expensive) alternative. If shipping by road, a load of 10 pallets is too large for a single van, so a larger vehicle would be required.
