  1. Terminology

2.1           Oeltechnik Service GmbH is hereinafter referred to as the Supplier.

2.2           The respective contractual partner of Oeltechnik Service GmbH is referred to as the Customer.


  1. Offer / Orders / Acceptance

3.1           The Supplier's offers are subject to change without notice unless they contain a binding period.       

3.2           Ordering and acceptance must be in writing. Verbal ancillary agreements in connection with the orders are only effective if they have been confirmed in writing by the Supplier.     


  1. Prices

4.1           The prices for deliveries of goods are EXW from the Waghäusel plant in accordance with Incoterms 2020.

4.2           Goods and             /or services will be invoiced according to offer package prices or according to time and effort.

4.3           The costs for any necessary tools, instruments, spare parts, travel and stays and holiday-related trips home etc., as well as certifications or legalizations of chambers of commerce as well as customs duties and all other duties, fees and taxes levied outside the Federal Republic of Germany are to be borne by the Customer. In the case of delivery, including customs or other charges, the stated price is based on the rates applicable at the time of the offer. The actual costs are calculated.     

4.4           If the Customer's order is not placed in Euros (€), the Supplier may demand that the value ratio existing at the time of the offer be maintained.

4.5           All prices will be invoiced – insofar as the delivery, work and/or services are subject to VAT – plus VAT in the amount prescribed by law on the day of invoicing.


  1. Terms of payment

5.1           Invoices are payable within 30 days of invoicing or – if the Supplier so requests – payment shall be made on an irrevocable letter of credit, which shall be opened in favor of the Supplier at short notice after receipt of the order confirmation and shall be opened by Deutsche Bank AG Frankfurt (Federal Republic of Germany) or another bank at the Supplier's discretion. It is to be confirmed. The letter of credit must be denominated in Euro (€). In addition, the "Uniform Guidelines and Customs for Documentary Letters of Credit" (ERA 600, revision 2006) of the International Chamber of Commerce (Paris) apply. All costs arising from the opening and maintenance of the letter of credit are borne by the Customer.

5.2           The Customer is not entitled to any deduction for e.g., taxes, fees, etc.

5.3           For the timeliness of payments, it is decisive that the Supplier can dispose of the credit note without reservation and that there are no reclaim reservations; in the case of cheques or bills of exchange, that the possibility of timely redemption and crediting in the ordinary course of business is given. The Customer shall bear expenses and costs in connection with the discounting and submission of cheques and bills of exchange.

5.4           If it is impossible to transfer the payments from the country from which the payment is to be made at the time of the due date, the Customer must nevertheless pay the equivalent of the amount owed to a bank in this country on time at the Supplier's discretion at its exclusive availability. The Customer compensates for the exchange rate deterioration of the amounts paid in non-agreed currency by making a corresponding additional payment. However, the Supplier can also either suspend the execution of the order at his discretion until the Customer can transfer the payments again, or he can withdraw from the order without rescission.

5.5           If the Customer is in default with his payment obligation in whole or in part, the Supplier is entitled to claim default interest equivalent to the annual EURIBOR rate plus 8% for payment in the amount of the delayed portion from the due date until the current receipt of payment. The possibility to claim higher damages and to assert all other rights remain unaffected.

5.6           The Customer can only offset such claims or assert a right of retention if he is entitled to legally binding or undisputed counterclaims from the contract.

5.7           If the Customer's financial circumstances deteriorate after the conclusion of the contract, the Supplier is entitled to refuse the services until the Supplier's claims have been fulfilled or security is guaranteed for claims that are not yet due.


  1. Delivery and execution deadlines

6.1           Delivery and execution dates for goods, work, or services require a written agreement. Partial deliveries are permissible.

6.2           The delivery period begins on the day of receipt of the Supplier’s written order confirmation by the Customer. However, it does not start under any circumstances before clarifying all technical details and fulfilling the Customer's obligations to cooperate, particularly the provision of documents, approvals, releases, and performance of the agreed down payment.

6.3           If the non-compliance with the delivery and/or execution deadline is due to labor strikes or other unforeseeable events through no fault of the Supplier, such as lack of materials or energy, incorrect or late deliveries (despite careful selection of suppliers) and the non-compliance could not be prevented even with the application of customary care and reasonable use, the delivery and/or  execution period extended by the duration of the hindrance plus a reasonable start-up period. This also applies if the delivery and/or execution period is delayed as a result of force majeure or other events. Events of force majeure include, in particular, fire, war or war-like acts, riots, mutiny, mobilization, requisition, flooding, earthquakes, other natural disasters, epidemics, quarantine measures, strikes, and lockdowns, restrictions on foreign exchange transfers as well as transport and export restrictions. In case the Customer proves that such an extension is unreasonable for him, he is entitled to withdraw from the unfulfilled part of the contract to the extent that this cannot be fulfilled within a reasonable period of time.

6.4           If the Customer proves that – with the exception of the cases referred to in 6.3 – he has suffered damage as a result of the delay, he may claim compensation of a maximum of 0.1% of the price of the goods or work or service in arrears for each full week of delay, but in no case more than 5% of the value of the goods delivered, or the work or service provided, in total.

6.5           If the Supplier is responsible for the non-compliance with the delivery period, the Customer may terminate in writing from the unfulfilled part of the contract after the expiry of a reasonable grace period.

The Customer may only pledge the reserved goods with the Supplier’s consent or assign them as security.

At the Supplier's request, the Customer is obliged to notify his Customers of the assignment of claims and provide the Supplier with the information and the documents necessary to assert the Supplier's rights against the Customer's customers.

8.6           If the value of the security exceeds the claim to be secured by 10%, the Supplier is obliged to release the reserved goods at the request of the Customer.

The Customer supports the Supplier's service technician to prevent avoidable delays in work.
