Differences between CFR, CPT, DAF and DDP and its menaing

Dear Sir/Madam
In some shipping docs or replied messages, we sometimes will see these words as CFR, CPT, DAF and DDP. Please would you explain to me what do they mean and its differences? And under what conditions and terms would be used?
Well, if my question is not clear enough to let you figure out please let me know. I’ll try my best to get some example sentences?
Thanks a lot,
Best wishes,

Hi Kelly

Those are standard abbreviations for some of the international shipping terms (“Incoterms”):

CFR = cost and freight
CPT = carriage paid to
DAF = delivered at frontier
DDP = delivered duty paid

Basically, “Incoterms” describe which costs are included in the price quoted in a contract.

There are more Incoterms. Here is a link for you:
