They have wrought strenuously with their logistics partners to reduce costs,expedite distribution times,better manage risks and automate information flows.This article aims at discussing various issues of a letter of credit which helps supply chain as a tool.

Documentary Credit:

The Uniform Customs and Practice for Documentary Credits 600 (1997 Revision) regulates mundane market practices within the letter of credit related areas. It defines a number of terms cognate to letters of credit that categorize the sundry actors within any given transaction.These are crucial to understanding the role of financial institutions play within.These include the advising bank is the bank that will apprise the beneficiary or their nominated bank, and provide the beneficiary or their nominated bank with any amendments to the letter of credit.To make a letter of credit firstly, it is required to have an updated trade license.Moreover, audit report,Import registration certificate, Chamber House membership, Income tax certificate, Vat registration etc. are required.

Blockchain can help:

Blockchain and letter of credit trade finance relates to the process of certain financing activities in areas of commerce and international trade. Financing includes products such as lending and issuing letters of credit, factoring export credit, indemnification of bills of lading that are old world methods of managing shipping of goods and accommodations. There is a potential to supersede these paper processes with digitized operations utilizing block chain technology. Conducting international trade requires a number of participants to interact with each other such as exporters,banks,shipping companies,port related entities, and customs.

Reduced fraud:

A letter of credit usually involve some manual procedures and a possibility of documentary fraud exists. So that the process can be ineffective and extravagant. These challenges can be addressed utilizing blockchain technology.In a block chain if we consider a typical international trade, we can see that the exporter,custom importer indemnification and importer bank each of them has representative nodes connected to a private block chain which replicate transformation information as it occurs on the network at any given point and time the information ledger across all nodes is in sync.

Submission of docs:

In block chain there is a genuine solution to initiate the contract. The exporter uploads the indispensable documents such as letter of credit, bill of lading and indemnification documents from the decentralized application.Exporter then submits the contract on the block chain .Once the the exporter submits the the contract, a transaction is sent to block chain. Transactions remain pending until the mining is consummated. A miner mines the transaction and integrates it to the block chain. Once the transaction is prosperously integrated to block chain a unique address is engendered where information is stored on the ledger. This engenders a unique tamper proof contract engendered by the exporter.The customs authenticates onto the decentralized application. After verifying the relative documents, custom officer approves the contract. The custom fee is processed on the block chain.Importer authenticates in onto the decentralized application in case the goods are damaged, that is the scenario here. The importer upload the indemnification documents and proof of damage on block chain insurer authenticated in onto the decentralized application.Insurer checks the indemnification documents and proof of damaged goods.


From the above discussion it is almost clear that letter of credit is an inevitable tool of business.But when we use letter of credit in the old way, it is sometimes open to fraud and less dependable. Block chain technology can help us in this regard to make this tool of business and supply chain more dependable.HSBC and some other international banks already started to use this technology in handling documentary credit. It is a good news for the international business community and supply chain managers also.
