Cl. 15 two or more ports countingi as one.
While it mentions that "within each such grouping or combination" shall count as one port for purposes of calculating freight and demurrage only....
What exactly does the "within each such grouping or combination" means? Is there any specific definition on this term?
Can be a range. For instance, ARA means the range that covers Amsterdam, Rotterdam and Antwerp. That range would count as one port for the calculation of freight.
