Bill of lading means the transport document ("marine", "ocean" or "port-to-port" or similar), however named, covering sea shipment only. Data in a bill of lading, when read in context with the credit, the document itself and international standard banking practice, need not be identical to, but must not conflict with, data in that document, any other stipulated document or the credit, according to UCP 600 and ISBP. This article has provided the general guideline of the discrepancies on the basis of UCP 600, ISBP 681 and the ICC Banking Commission Opinions, for the solution of the unpaid problems of the credit transactions. I have studied especially the ICC Banking Commission Opinions and the DOCDEX Decisions on the bill of lading after UCP 600, the international standard banking practice (ISBP 681), and the recent Korean cases. As such, this article would fill a need gap in the market between the general principles in the UCP provisions and the daily job of the practitioner. The credit practitioners are suggested to this resulting guidance whenever doubts arise as to how to check the credit documents in daily practice.
