Incoterms are used for determining the costs and risks between buyers and sellers in the international trade.

Incoterms define the rights and obligations of the seller and the buyer regarding supply and transport documents, the risk transition between salesman and buyer, as well as the cost division between salesmen and buyers.

Incoterms are valid only if they were expressly contractually agreed upon and in the sales contract or eg. in offers, general sales conditions, orders, order confirmations, etc. mentioned or are held in a separate declaration/agreement.
