Yes. The logistics problem in Ukraine, as correctly noticed by Mykhailo, is huge indeed. The width of the railways in Ukraine and the European countries is different. That's why, in order to transport through western borders, the grain needs to be unloaded from the Ukrainian wagons and put on the western machines in order to be transported further. This is problem number one.
A related problem is that the capacity of our common checkpoints at the borders does not always allow for such a procedure. The checkpoints with such facilities are limited, which puts additional limits on the capacity of the Ukrainian railway to transport the exports. This is problem number two.
Problem number three that we can point to is the capacity of the European ports to store Ukrainian grain. European ports have the facilities for the usual amount of grain that has been transported, plus certain additional storage. Now, this huge amount that can come from Ukraine is simply...there is very limited space to store it.
Ukrainian farmers have started investing in buying older storage in Europe. Of course, those producers who can assemble money to buy them try to put additional investments into buildings and storage in Europe, but this is a huge investment for them and not everyone can afford it.
