Answer: both D/P T/R and D/A collection methods are collection methods, and the exporter must draw a time draft to pick up the goods after shipment.

D/P T/R is a D/P method, that is, D/P borrows documents with trust receipts. After the importer accepts the draft, he borrows the draft to pick up the goods with the trust receipt. In the future, if the importer refuses to pay at maturity, the exporter will bear his own risk. This practice is similar to D/A in nature.

D/A is D/A, which means that the exporter's D/A is subject to the importer's acceptance of the draft. It is risky for exporters to use D/A, and they may suffer losses in both aspects of payment.
