I am pleased that all arrived in good shape and condition and that documentation were alright.
About the 6kg short : it would wonder us because the packing of bags is full automated with full automated bagging line and weightscales (2 scales). There should not be underweight on any order. How did you weight about the 6 kgs less in 640 bags ? Can you explain ?
About unloading the containers without pallets :
If the containers are without pallets, than you have to unload the bags manulay (bag per bag) from the container. It is a hard job and takes labour-time. Overhere, we don’t do it anymore since long time because it is too heavy work for worker and labour is too expensive for it. I do not know atyour place, but such containers have to be unloaded by hand. There is no instruction video or whatever. You put forklift near to the open container-door with an empty pallet next to the container and a person in the container takes the bags out of the container and puts it on the empty pallet that is on the forklift. When the pallet is full, you bring the pallet to the warehouse and this you do till container is empty.
Annexed you see picture how the container is loaded in case you load 18 Mtons in a 20ft container.
If you want more quantity to order in a container and not want to unload by hand (bag per bag), than better option is to take a 40ft container with 25.000 kgs on pallets.
