‘There is nothing that would prevent you from for example using DDU, as long as you and the seller agree that the shipment is DDU [location], Incoterms 2000. The agreement between you and the seller prevails, and if you both agree, there is no reason to not use it. Incoterms 2000 should appear on the contract between Buyer and Seller.
Incoterms rules are not law, that is, they are not mandatory. They are a set of guidelines designed by the International Chamber of Commerce for companies involved in international trade, but no one is mandated to use them. It’s just much more convenient to use them than to negotiate international terms of trade for each shipment.
The issue with the use of an “old” Incoterm is that, should a dispute arise between the two of you, then the ICC may decline to arbitrate the dispute. I am not sure how long the ICC will still be willing to arbitrate a problem arising under the DDU shipment (or any other 2000 Incoterm rule), but I don’t think that they would stop on January 1, 2011. Even if they actually did, you should have no problem finding an arbitrator familiar with DDU to settle the issue.’
