Online Order System (OOS): Terms and Conditions of Use

An account in the Online Order System (OOS) enables a user to register online for participation in a trade fair (online registration), to place online orders for products or services and – subject to admission as an exhibitor – to create and update an online exhibitor’s profile. Other applicable regulations, each in their latest version, in addition to these Terms and Conditions of Use, are the Terms and Conditions for Participation of Messe Düsseldorf GmbH, the Technical Regulations of Messe Düsseldorf GmbH, the Messe Düsseldorf Privacy Policy and, if applicable, the relevant partners’ terms and conditions on ordering and supplying products or services (available, in each instance, in OOS under “GTC”) as well as any other general terms and conditions that may be included (each to be called up on the relevant website). 

As regards the ordering of products and services from Messe Düsseldorf via OOS, the relevant contract shall be deemed concluded no later than the point in time when the ordering status “Approved” is shown in the list of orders kept by the Stand Management.

To create and update an online exhibitor’s profile, exhibitors may enter and edit the relevant details with a view to presenting their companies on the internet. To promote themselves, exhibitors may also add graphics, photographs, text and links to their own websites. Each exhibitor bears their own responsibility for any content added by them. Should a third party make claims towards Messe Düsseldorf for the violation of trademark rights, copyrights or industrial property rights on account of entries made by an exhibitor, then the relevant exhibitor shall indemnify Messe Düsseldorf against any liability whatsoever. 

Users may access their OOS account by using their personal email address as a login name together with a user-defined personal password. There are three ways to create this account. 

(1) A user registers with Messe Düsseldorf outside OOS. If it is possible to admit the user to the relevant trade fair, then they are subsequently sent an email (usually shortly before an official letter of admission is sent), requesting that they register via the specified link.

(2) A user who already has an account and who has a stand order within that account invites another potential user to join their own stand order: The invited person is then sent an email, asking them to register via the specified link (see also below, option (3)(b)). 

(3) A user calls up the OOS homepage and registers there, requesting an OOS account. However, when an account has been created, the user cannot place orders until the account has been associated with a stand order. This association cannot be created by the user. It is created

(a) if the user has been specified by Messe Düsseldorf as a so-called administrator in the stand order or 

(b) if an existing user, who has already been accepted, invites the prospective user to join their stand as an additional user (see above, clause 2).

The other party in the contractual relationship with the exhibitor is either Messe Düsseldorf GmbH itself or a third-party contractor delivering a product or service that has been ordered. Messe Düsseldorf GmbH bears no liability for damage caused by misuse of the OOS password.

Documentary statements (especially online registrations and orders) sent by a user to Messe Düsseldorf via OOS shall be considered as delivered at the point in time and to the extent that they arrive in Messe Düsseldorf GmbH’s electronic mailbox.

Messe Düsseldorf bears no liability for damage caused by technical malfunctions (e.g. server connection failures), faulty transmission and/or force majeure.

This contract shall be subject to German law, irrespective of nationality or server location.


The place of performance shall be Düsseldorf.
