If after an offer has been made, a delivery confirmed or a delivery agreement has been entered into, circumstances arise which prevent us from fulfilling what has been mentioned, we are not responsible for the consequences thereof. This applies, for example, to war, mobilization, requisition, seizure, changes in the currency market, export or import bans, labor disputes, an insufficient supply of raw materials, lack of means of transport, fire and factory accidents, as well as deficiencies/errors in deliveries from subcontractors or delays in such deliveries as a result of such circumstances which are dealt with in this point. In such cases, in the event of a permanent impediment to delivery, any of the parties may wholly or partially withdraw the offer, the delivery agreement or the sale of the affected product/goods. If the delivery obstacle is temporary, the delivery time can be extended.
