Exporter makes sure the L/C is valid and corresponds to the timetables agreed with the Importer regarding both the delivery of the goods and payments. Another question: can the documents be negotiated or transferred within the term of the L/C? Can the Exporter accept all the restrictions and limitations of the L/C? Are there any impossible conditions (for instance, in contravention of the foreign exchange regime) or wrong details (name of a port which does not exist, etc.)
