Incoterms are international commercial terms published by the International Chamber of Commerce that define the responsibilities of importers and exporters in international transactions. The current Incoterms 2000 have 13 terms that are divided into four groups based on when risk and responsibility transfer from seller to buyer. While Incoterms clarify risk transfer, they do not determine property rights, name carriers, or address contract breaches. Users must be aware that Incoterms only apply if incorporated into sales contracts and do not replace full contract terms.
