DDU

A withdrawn Incoterms rule, replaced by DAP in 2010 — still widely quoted despite no longer existing.

Delivered Duty Unpaid. Removed from the Incoterms rules in the 2010 revision and replaced by DAP.

It persists in contracts and quotations more than a decade later, particularly in e-commerce shipping. Because it no longer forms part of the published rules, a contract citing DDU without defining it leaves the parties to argue about what it meant - which is a good reason to write DAP instead.
