The 2000 revision of Incoterms took account of the spread of customs-free zones, the increased use of electronic communication, and the changes in transport practices. The new version offers a simpler and clearer presentation of the definitions of all the terms. As in the previous version, the trade terms of Incoterms 2000 are presented in a format which allows seller and buyer to follow a step-by-step process to determine their respective obligations.
