Full container or shared: FCL and LCL
With a full container load (FCL) you pay for the whole box and nobody else’s cargo travels in it; it is sealed at your supplier and opened at your door or warehouse. With less than container load (LCL) your cartons share a container with other shippers, are consolidated at a warehouse in China and split again after arrival, and you pay for the space and weight you use. Small shipments are cheaper shared. Past a certain volume a full container usually costs less, travels faster through the ports and is handled less, which is why the form suggests it when you get there.
