While visiting importers and producers of firewood in UK and Ireland as a native Lithuanian I was suprised how people calculate volume of firewood in bags, builder bags, barrow bags, carry bags or any other flexible packaging. As well bag is not neatly packed, but its just loose firewood in a bag.
When UK importers are asking for the price of wood, they clearly calculate dimensions of the box, how many boxes in 40ft container and what is the weight of one box. So they clearly understand how business should calculate such a product, but they never tell that to the people.
I even had requests to export firewood loose in big bags, but when I stated that is not efficient import, customers started to do numbers and imported crates since then.
There are different companies in the market, different products and quality, so these who buy kiln dried firewood in crates they win in this situation, because they have ready to use product and they know what they pay for the volume.
