What are the differences between the following incoterms and does anyone use other incoterms? SITE DELIVERY, CIP, CIF, and FOB

for site delivery , DDP delivery duty paid or DDU delivery duty unapaid can be used

Incoterms are pre-defined international commerce terms that clearly state responsibilities, costs and risks associated with transportation, insurance and delivery of goods for both buyers and sellers. Therefore, they should be used in every negotiation in order to avoid problems. 

The definition of all the Incoterms can be found at: http://www.iccwbo.org/products-and-services/trade-facilitation/incoterms-2010/the-incoterms-rules/
