The Incoterms rules or International Commercial Terms are a series of pre-defined commercial terms published by the International Chamber of Commerce (ICC) that are widely used in International commercial transactions or Procurement processes.

The most commonly used

EXW – Ex Works (named place of delivery)
The seller makes the goods available at his/her premises. The buyer is responsible for uploading. This term places the maximum obligation on the buyer and minimum obligations on the seller. The Ex Works term is often used when making an initial quotation for the sale of goods without any costs included. EXW means that a seller has the goods ready for collection at his premises (works, factory, warehouse, plant) on the date agreed upon. The buyer pays all transportation costs and also bears the risks for bringing the goods to their final destination. The seller does not load the goods on collecting vehicles and does not clear them for export. If the seller does load the goods, he does so at buyer's risk and cost. If parties wish seller to be responsible for the loading of the goods on departure and to bear the risk and all costs of such loading, this must be made clear by adding explicit wording to this effect in the contract of sale.
FCA – Free Carrier (named place of delivery)
The seller delivers goods, cleared for export, to the buyer-designated carrier at a named and defined location. This is used for any mode of transport. The seller must load goods onto the buyer's carrier. The key document signifying transfer of responsibility is receipt by carrier to exporter.
DAP – Delivered at Place (named place of destination)
Seller pays for carriage to the named place, except for costs related to import clearance, and assumes all risks prior to the point that the goods are ready for unloading by the buyer.
FOB – Free on Board (named port of shipment)
The seller must load the goods on board a vessel designated by the buyer. Cost and risk are divided when the goods are actually on board of the vessel. The seller must clear the goods for export. The term is applicable for maritime and inland waterway transport only but NOT for multimodal sea transport in containers (see Incoterms 2010, ICC publication 715). The buyer must instruct the seller the details of the vessel and the port where the goods are to be loaded, and there is no reference to, or provision for, the use of a carrier or forwarder. This term has been greatly misused over the last three decades ever since Incoterms 1980 explained that FCA should be used for container shipments.
It means the seller pays for transportation of goods to the port of shipment, loading cost. The buyer pays cost of marine freight transportation, insurance, uploading and transportation cost from the arrival port to destination. The passing of risk occurs when the goods pass the ship's rail at port of shipments.

CFR – Cost and Freight (named port of destination)
Seller must pay the costs and freight to bring the goods to the port of destination. However, risk is transferred to the buyer once the goods are loaded on the vessel. Insurance for the goods is NOT included. This term is formerly known as CNF (C&F, or C+F). Maritime transport only.
CIF – Cost, Insurance and Freight (named port of destination)
Exactly the same as CFR except that the seller must in addition procure and pay for the insurance. Maritime transport only.

 

Other

CPT – Carriage Paid To (named place of destination)
The seller pays for carriage. Risk transfers to buyer upon handling goods over to the first carrier at place of shipment in the country of export.
This term is used for all kind of shipments.
CIP – Carriage and Insurance Paid to (named place of destination)
The containerized transport/multimodal equivalent of CIF. Seller pays for carriage and insurance to the named destination point, but risk passes when the goods are handed over to the first carrier.
DAT – Delivered at Terminal (named terminal at port or place of destination)
The Seller delivers when the goods, once unloaded from the arriving means of transport, are placed at the Buyer's disposal at a named terminal at the named port or place of destination. "Terminal" includes any place, whether covered or not, such as a quay, warehouse, container yard or road, rail or air cargo terminal. The Seller bears all risks involved in bringing the goods to and unloading them at the terminal at the named port or place of destination.
DDP – Delivered Duty Paid (named place of destination)
Seller is responsible for delivering the goods to the named place in the country of the buyer, and pays all costs in bringing the goods to the destination including import duties and taxes. The seller is not responsible for unloading. This term is often used in place of the non-Incoterm "Free In Store (FIS)". This term places the maximum obligations on the seller and minimum obligations on the buyer.
FAS – Free Alongside Ship (named port of shipment)
The seller must place the goods alongside the ship at the named port. The seller must clear the goods for export. Suitable only for maritime transport but NOT for multimodal sea transport in containers (see Incoterms 2010, ICC publication 715). This term is typically used for heavy-lift or bulk cargo.
