在出口业务中，由于种种原因造成单据不符，即单据存在不符点，而受益人又因时间条件的限制，无法在规定期限内更正，则有下列处理方法：

In export business, if documents are inconsistent due to various reasons, that is, there are discrepancies in documents, and the beneficiary cannot correct them within the prescribed time limit due to time conditions, the following treatment methods shall be adopted:

凭保议付。受益人出具保证书承认单据瑕疵，声明如开证行拒付，由受益人偿还议付行所垫付款项和费用，同时电请开证人授权开证行付款。

Negotiation against warranty. Beneficiary issues a letter of guarantee acknowledging the defects of the documents, stating that if the issuing bank refuses to pay, beneficiary will reimburse the negotiating bank for the amount and charges advanced by the negotiating bank, and at the same time cable requesting the applicant to authorize the issuing bank to make payment.

·表提。议付行把不符点开列在寄单函上，征求开征行意见，由开证行接洽申请人是否同意付款。接到肯定答复后议付行即行议付。如申请人不予接受，开证行退单，议付行照样退单给受益人。

table. The negotiating bank will list the discrepancies on the sending letter, seek the advice of the issuing bank, and the issuing bank will contact the applicant to see if it agrees to pay. The negotiating bank negotiates on receipt of the affirmative reply. If the applicant refuses to accept the documents, the issuing bank will return the documents and the negotiating bank will return the documents to the beneficiary.

电提。议付行暂不向开证行寄单。而是用电传和传典通知开证行单据不符点。如开证行同意付款，再行议付并寄单，若不同意，受益人可及早收回单据，设法改正。

Electric lift. The negotiating bank will not send documents to the issuing bank temporarily. Instead, the issuing bank is advised of the discrepancies by telex and facsimile transmission. If the issuing bank agrees to pay and then negotiates and sends the documents, if not, the beneficiary may recover the documents as soon as possible and try to make corrections.

有证托收。单据有严重不符点，或 信用证 有效期已过，已无法利用手上的 信用证 ，只能委托银行在向开证行寄单函中注明" 信用证 项下单据作托收处理"，作为区别，称为"有证托收"

Documentary collection. If there are serious discrepancies in documents, or the validity of the letter of credit has expired and the credit in hand is no longer available, the bank can only be entrusted to mark "documents under the Credit for collection" in the letter of credit to the issuing bank as the difference, which is called "certified collection"
