The reminder is that the exporter informs or urges the foreign importer to promptly open the letter of credit through the bank in accordance with the contract, so that the exporter can ship the goods in time. Not every business needs a reminder, in general, it needs to be certified: 1. The date of shipment specified in the contract is longer than the date of signing the contract, or the contract stipulates that the buyer should open the letter of credit at a certain time before the shipment period. 2. The seller prepares the goods in advance and can ship them in advance, and can negotiate with the buyer for early delivery. 3. The foreign buyer did not issue a letter of credit within the time limit stipulated in the contract. 4, the buyer's reputation is not good, deliberately delay the issuance of the certificate, or due to funding and other issues can not afford to pay the deposit to the issuing bank. The reminder is to urge the other party to go through the formalities for issuing the certificate in time by letter, telegram, telex or other means, and send the letter of credit to the seller so that the seller can stock up or ship the goods in time. In order to ensure that the contract is fulfilled on time and the compliance rate is increased, it is necessary for the seller to promptly and urge the buyer to open a letter of credit in accordance with the contract. The buyer's issuance of the certificate at the agreed time is a precondition for the seller to perform the payment contract. In the case of a large transaction or a commodity transaction specially customized according to the buyer's request, it is especially important for the buyer to open the letter of credit in time. Otherwise, the seller cannot arrange production and on time. Organize the source of goods to prevent the buyer from defaulting, resulting in the inability of the goods to be shipped in time, or the market conditions to change and report the loss: the heavy goods make the goods not sold, seriously affecting the company's continued operations. Under normal circumstances, the buyer's letter of credit should be opened to the seller 15 days before the shipment. In principle, new customers who are not very familiar with the credit status insist on the 30 days or 45 days or even longer period before the shipment period, and flexibly grasp the date of issuance of the letter of credit in line with the production processing period and the requirements of the customers. In actual business, foreign customers often delay the issuance of certificates when they encounter market changes or lack of funds. Therefore, exporters should check the buyer's licenses frequently. Need to certify 1. The date of shipment specified in the contract is longer than the date of signing the contract, or the contract stipulates that the buyer should open the letter of credit at a certain time before the shipment period. 2. The seller prepares the goods in advance and can ship them in advance, and can negotiate with the buyer for early delivery. 3. The foreign buyer did not issue a letter of credit within the time limit stipulated in the contract. 4, the buyer's reputation is not good, deliberately delay the issuance of the certificate, or due to funding and other issues can not afford to pay the deposit to the issuing bank. 5. The date of signing and the date of performance should be far apart. Before the date of the contract issuance, the letter will indicate the importance of the transaction. And remind the other party to issue the certificate in time.
