Part IV of the Convention, “Final Provisions,” includes 13 articles dealing with important issues such as the relationship between the Convention and other treaties, entry into force, reservations with respect to certain articles or parts of the Convention, and denunciation.
Given that said issues are not addressed in a systematic fashion within Part IV, our Commentary will not address each article separately. We will instead use a topical approach.
§ 11.2 Commentary
§ 11.2.1 Articles 90 and 99(3) (6): Relationship with other international instruments
This Convention does not prevail over any international agreement which has already been or may be entered into and which contains provisions concerning the matters governed by this Convention, provided that the parties have their places of business in States parties to such agreement.
Article 99(3) (6)
(3) A State which ratifies, accepts, approves or accedes to this Convention and is a party to either or both the Convention relating to a Uniform Law on the Formation of Contracts for the International Sale of Goods done at The Hague on 1 July 1964 (1964 Hague Formation Convention) and the Convention relating to a Uniform Law on the International Sale of Goods done at The Hague on 1 July 1964 (1964 Hague Sales Convention) shall at the same time denounce, as the case may be, either or both the 1964 Hague Sales Convention and the 1964 Hague Formation Convention by notifying the Government of the Netherlands to that effect.
