Common use of General Terms Clause in Contracts

General Terms. On placing an order, the following conditions become part of the contract unless conditions to the contrary are agreed upon in writing. The terms stipulated hereafter invalidate deviating conditions of the purchase even when such conditions on which the purchase bases his order are not expressly challenged. If General Terms of Business are not referred to in an offer to a purchaser or merchant, they nevertheless are still applicable if there has been a reference to General Terms of Business in a former business contract.
