一、信用证有效期一般多久
信用证有效期是由开证人决定的，一般开证申请人会定在交货期20天左右。 L/C规定受益人议付应该在出货15-21天，出货这个概念有笼统，有的时候开证人要求是进仓后15--21天,有时候是船开15--21天,有时候是提单签发日15--21天，这取决于开证人。 另外,国际惯例中规定，议付行收到议付单据后2周内必须给与议付，这个日期不是明文规定的，而是国际上的惯例。
How long is the validity of the letter of credit
The validity period of the l/C is decided by the issuer. Generally, the applicant will set the date of delivery at about 20 days. L/C stipulates that the beneficiary should negotiate within 15-21 days of shipment. Shipment is a general concept. Sometimes the issuer requires 15-21 days after warehousing, sometimes the vessel sails 15-21 days, and sometimes the bill of lading is issued 15-21 days, depending on the issuer. In addition, it is stipulated in the international practice that the negotiating bank must negotiate the documents within 2 weeks after receiving them.
