In view of the changes made to Incoterms from time to time, it is important to ensure that where the parties intend to incorporate Incoterms into their contract of sale, an express reference is always made to the current version of Incoterms. This may easily be overlooked when, for example, a reference has been made to an earlier version in standard contract forms or in order forms used by merchants. A failure to refer to the current version may then result in disputes as to whether the parties intended to incorporate that version or an earlier version as a part of their contract. Merchants wishing to use Incoterms 2000 should therefore clearly specify that their contract is governed by «Incoterms 2000.
