In some situations, it may not be possible at the time when the contract of sale is entered into to decide precisely on the exact point or even the place where the goods should be delivered by the seller for carriage. For instance reference might have been made at this stage merely to a «range» or to a rather large place, for example, seaport, and it is then usually stipulated that the buyer has the right or duty to name later on the more precise point within the range or the place. If the buyer has a duty to name the precise point as aforesaid his failure to do so might result in liability to bear the risks and additional costs resulting from such failure (B5/B7 of all terms). In addition, the buyer's failure to use his right to indicate the point may give the seller the right to select the point which best suits his purpose (FCA A4).
