The States Parties to this Convention,
Bearing in mind the broad objectives in the resolutions adopted by the sixth special session of the General Assembly of the United Nations on the establishment of a New International Economic Order,
Considering that the development of international trade on the basis of equality and mutual benefit is an important element in promoting friendly relations among States,
Being of the opinion that the adoption of uniform rules which govern contracts for the international sale of goods and take into account the different social, economic and legal systems would contribute to the removal of legal barriers in international trade and promote the development of international trade,
(1)
If a Contracting State has two or more territorial units in which, according to its constitution, different systems of law are applicable in relation to the matters dealt with in this Convention, it may, at the time of signature, ratification, acceptance, approval or accession, declare that this Convention is to extend to all its territorial units or only to one or more of them, and may amend its declaration by submitting another declaration at any time.
(2)
These declarations are to be notified to the depositary and are to state expressly the territorial units to which the Convention extends.
(3)
If, by virtue of a declaration under this article, this Convention extends to one or more but not all of the territorial units of a Contracting State, and if the place of business of a party is located in that State, this place of business, for the purposes of this Convention, is considered not to be in a Contracting State, unless it is in a territorial unit to which the Convention extends.
(4)
If a Contracting State makes no declaration under paragraph (1) of this article, the Convention is to extend to all territorial units of that State.
