Since the implementation of International Standard Banking Practice(ISBP) in 2003, ICC Publication No. 645 has become an invaluable help to the documentary credit practitioners including banks, companies, transportation and insurance companies etc. However, with the approval of UCP 600 in October 2006, it has become necessary to provide an updated version of the ISBP. It should be emphasized that this ISBP is an updated version as opposed to a revision of ICC Publication No. 645. The new ISBP has been implemented concurrently with UCP 600 since July 1st, 2007. The first necessity was to replace UCP 500 article numbers with those of UCP 600. Second, where it was felt proper, the contents of some paragraphs that appear in ICC Publication No. 645 and that have been covered in UCP 600 have been removed from the updated version of the ISBP. This explains the reduction in the number of paragraphs from 200 to 185. The international standard banking practices documented in the new ISBP are consistent with UCP 600. This ISBP does not amend UCP 600. It explains how the practices articulated in UCP 600 are applied by documentary practitioners. The new ISBP and the UCP 600 should be read in their entirety and not in isolation. It should be kept in mind that any terms in a documentary credit which modifies or excludes the applicability of a provision of UCP 600 may also have an impact on the international standard banking practices. Consequently, when parties concerned must take into account any terms in a documentary credit that expressly modifies or excludes a rule contained in UCP 600.
