Artikel 14

If a Contracting State has two or more territorial units which have their own rules of law in respect of products liability, it may, at the time of signature, ratification, acceptance, approval or accession, declare that this Convention shall extend to all its territorial units or only to one or more of them, and may modify its declaration by submitting another declaration at any time.
These declarations shall be notified to the Ministry of Foreign Affairs of the Netherlands, and shall state expressly the territorial units to which the Convention applies.
