If you want to ship a 20-foot container instead of a 40-foot container, it’s worth noting that the latter usually costs just 20-25% more than the former. The total cubic capacity of an FEU is 2,389 cu ft (67.7 m3) and the payload capacity is 61,200 lbs (27,600 kg). You can fit between 20-21 standard pallets in an FEU.
