Containers 
                                      intended for intercontinental use have external 
                                      nominal dimensions of:

                                            19.875 feet (6.058m) as 20 feet 
                                            29.9375 feet (9.125m) as 30 feet

                                            feet (2.591m) and 9.5 feet (2.896m) | 
                                         
                                       
                                         
                                       All above dimensions 
                                      have permissible tolerances.  
                                       
                                      The 20 feet (20') and 40 feet (40') containers 
                                      are very popular in ocean freight. The 8.5 
                                      feet (8.5') high container---8 feet 6 inches 
                                      (8' 6") high container---is often referred 
                                      to as standard container. 
                                       
                                      The demand for the high cube container---hicube---is 
                                      increasing. The popular high cube container 
                                      has a normal height of 9.5 feet (9.5' or 
                                      9' 6"). 
                                       
                                      There are half height containers (4.25' 
                                      or 4' 3" high) designed for heavy loads 
                                      such as steel rods and ingots, which absorb 
                                      the weight limit in half the normal space. 
                                       
                                      The most widely used type of container is 
                                      the general purpose (dry cargo) container 
                                      (please see Container Classifications) having 
                                      a nominal length and height of 20' x 8.5', 
                                      40' x 8.5', and 40' x 9.5'. Referring to 
                                      the Dimension of General Purpose Containers 
                                      below, the dimensions shown in the table 
                                      are not fixed, that is, the external and 
                                      internal dimensions may vary among containers 
                                      of the same length and height. 
                                       
                                      The container capacity is the total cube 
                                      a container can accommodate. The term cube 
                                      often refers to the cubic measurement of 
                                      cargo. The capacity (i.e., the internal 
                                      volume) is determined by multiplying the 
                                      internal dimensions, that is, the product 
                                      of internal length, width and height. The 
                                      capacity may vary among containers of the 
                                      same length and height.
