A sight draft is used when the exporter wishes to retain title to the shipment until it reaches its destination and payment is made. Before the shipment can be released to the buyer, the original ocean bill of lading (the document that evidences title) must be properly endorsed by the buyer and surrendered to the carrier. It is important to note that air waybills of lading, on the other hand, do not need to be presented in order for the buyer to claim the goods. Hence, risk increases when a sight draft is being used with an air shipment.
In actual practice, the ocean bill of lading is endorsed by the exporter and sent via the exporter's bank to the buyer's bank. It is accompanied by the sight draft, invoices, and other supporting documents that are specified by either the buyer or the buyer's country (e.g., packing lists, consular invoices, insurance certificates). The foreign bank notifies the buyer when it has received these documents. As soon as the draft is paid, the foreign bank turns over the bill of lading thereby enabling the buyer to obtain the shipment.
There is still some risk when a sight draft is used to control transferring the title of a shipment. The buyer's ability or willingness to pay might change from the time the goods are shipped until the time the drafts are presented for payment; there is no bank promise to pay standing behind the buyer's obligation. Additionally, the policies of the importing country could also change. If the buyer cannot or will not pay for and claim the goods, returning or disposing of the products becomes the problem of the exporter.
Time Drafts and Date Drafts
A time draft is used when the exporter extends credit to the buyer. The draft states that payment is due by a specific time after the buyer accepts the time draft and receives the goods (e.g., 30 days after acceptance). By signing and writing "accepted" on the draft, the buyer is formally obligated to pay within the stated time. When this is done the time draft is then called a trade acceptance. It can be kept by the exporter until maturity or sold to a bank at a discount for immediate payment.
A date draft differs slightly from a time draft in that it specifies a date on which payment is due, rather than a time period after the draft is accepted. When either a sight draft or time draft is used, a buyer can delay payment by delaying acceptance of the draft. A date draft can prevent this delay in payment though it still must be accepted.
When a bank accepts a draft, it becomes an obligation of the bank and thus, a negotiable investment known as a banker's acceptance. A banker's acceptance can also be sold to a bank at a discount for immediate payment.
