General conditions of business WOLF GmbH



The following terms and conditions of sale and delivery shall apply to all business relations between Wolf GmbH and companies within the meaning of § 14 (1) of the German Civil Code (BGB), as well as with legal entities under public law or special funds under public law. An entrepreneur is any natural or legal person who is acting in a commercial or independent capacity when concluding the transaction.

All orders placed by entrepreneurs, regardless of whether they were placed with Wolf GmbH via the online shop www.wolf.eu/shop or by other means, as well as our deliveries, services and offers to entrepreneurs, shall be based exclusively on these terms and conditions of business. Thus, they shall also apply to all future business relations even if they were not expressly agreed again. These Terms and Conditions shall be considered as accepted on taking delivery of the goods or performance at the latest.

General Conditions of Purchase of the buyer are not accepted. In accordance with the provisions of the General Data Protection Regulation (GDPR) and the German Federal Data Protection Act we point to our buyers that we process personal data required for the settlement of business relations by means of EDP and transmit these data only in-house.



Our offers are non-binding and without obligation. Contracts for delivery and all other agreements (including subsidiary agreements) as well as declarations of our representatives shall only become legally binding for us after our written confirmation. We do not render planning services. Proposals made and information provided by our representatives shall be non-binding. Illustrations, drawings, dimensions and weights or other performance data shall only be binding if this is expressly agreed in writing.
Business mail printed by data processing systems (e.g. order confirmations, invoices, credit notes and reminders) shall also be legally binding without signature.



  1. Our prices are net ex works or ex stock plus packaging, freight and VAT. With regard to orders without agreed prices, our prices shall apply which are valid according to the price list on the day of delivery.
    Part deliveries shall be invoiced separately unless expressly agreed otherwise.
  2. We reserve the right to make a corresponding price adjustment in the event of changes of material usage prices and personnel costs until the day of delivery. However, this shall only apply to periods of delivery of more than 4 months and for price adjustments up to 10%. A new price agreement shall be required for higher rates. If such an agreement is not made, we shall be entitled to withdraw from the contract by written notice within 14 days.



  1. If the payment conditions have not been agreed upon conclusion of the contract, the payment terms and payment dates specified in our invoices shall be binding. Deadlines for discounts and periods allowed for payment shall begin to run upon receipt of the invoice.
  2. The buyer may only offset his claims which are not contested or became res judicata.
  3. We are not obliged to accept bills and cheques. Credit notes for bills and cheques are made with value of the date when we can dispose of the countervalue.
  4. We charge default interest in the legal amount in the event of default in payment. Assertion of other damages shall not be excluded. All claims will be due immediately in the event of non-compliance with terms of payment, dishonouring of bills and cheques, cessation of payment or upon circumstances which reduce buyer’s credit worthiness or ability to pay. Furthermore, we shall be entitled to execute outstanding deliveries only against advance payment or withdraw from the contract after setting of a reasonable grace period and claim damages instead of performance.
  5. Otherwise, the following provisions of item IX shall apply with regard to the claims for dama ges of the buyer.



  1. Our deliveries are exclusively made with reservation of ownership (conditional commodity). Ownership passes to the buyer not before he redeemed his total liabilities including any balance claims from our goods delivered. The same shall apply if payments are made for specially described claims.
  2. Processing or transformation is always made for us as producer, however, without any obligation for us. If goods delivered by us are mixed or linked with other objects, the buyer shall assign the (joint) ownership to us of the corporeal thing created hereby, namely in proportion of the invoice value of our conditional commodity to the invoice value of the other goods used.
  3. The buyer may only sell or use our conditional commodity in the ordinary course of business. Pledging and assignment as security shall be inadmissible. By way of security and to the full extent, the buyer assigns the claims (including any balance claims) to us already now, which arise from resale or any other legal ground (further use, tortious act) with regard to the conditional commodity.
  4. The buyer shall be entitled to collection of the claims assigned to us. We may revoke the collection authorization in the event of default, cessation of payment, application to commence insolvency or composition proceedings or any other deterioration of the buyer’s assets. The buyer shall notify us immediately about attachments, seizures or any other orders or interferences by third parties.
  5. If the buyer defaults, we shall be entitled to demand re turn of the conditional commodity and get the actual possession of this conditional commodity by own action or authorized representatives, no matter where it is located. The buyer shall be obliged to return the conditional commodity to us. Furthermore, he shall be obliged to supply the information required and deliver documents for the enforcement of our rights.
  6. If the realizable value of the securities due to us in accordance with foregoing provisions exceeds the value of our claims by more than 10 %, we shall be obliged to release exceeding securities at our option upon buyer’s request.



  1. Delivery time information is only approximate. We shall only be in default if the performance is due and a written demand for payment was issued. Delivery day is the day of dispatch ex works and ex stock respectively.
  2. Delivery deadlines start with the date of our order confirmation. They do not start, however, prior to clarification of all execution details and all other conditions to be set by the buyer for the proper processing of the contract. The same is valid for delivery dates. Early deliveries are permitted.
  3. We shall also not be liable with regard to bindingly agreed periods and dates in the event of delays in delivery and of performance due to force majeure and events which considerably complicate or make delivery impossible not only temporarily - strike, lockout, breakdown, delay in supply with important raw and auxiliary materials even if the delay occurs at our supplier, in particular. These delays entitle us to postpone delivery for the period of the impediment plus a reasonable start-up period or to withdraw from the contract as a whole or in part. If delivery time is extended or we are released from our delivery commitment, the buyer may not derive a claim for damages from it. However, we may only rely on the circumstances mentioned if we notify the buyer immediately.
  4. We shall be entitled to make part deliveries. Any part delivery shall be considered as independent transaction.



  1. Shipment is made for the buyer’s account.
  2. Mode of shipment and shipping route, transport and packaging and other securities respectively shall be at our choice. We shall be entitled, however, not obliged to insure deliveries in the name and for account of the buyer.
  3. Risk passes to the buyer when shipment is handed over to the person performing the transport or left our works and stock respectively for shipment.
  4. If the buyer violates their duties to cooperate (e.g. by not timely retrieving the goods or by declining acceptance), we are entitled to store the goods at the buyer’s costs and risk and to demand compensation for the damages that have been caused so far (in particular storage costs) inclusive additional expenses after an extension of time has passed without any success.
  5. After the extension of time has passed without any success, we are also entitled to charge the ordered goods.
  6. If the above conditions apply, the risk of accidental loss or of accidental deterioration of the purchased item passes to the buyer at the point in time that the buyer will default on acceptance or payment.
  7. Our right of demanding compensation because of breach of duty or compensation instead of service respectively shall remain unaffected by this.
  8. With this, the goods are stated as accepted.
  9. Discharge of the goods is made at buyer’s expense.



  1. Goods are delivered free of production defects or defects in material. Claims based on defects shall not exist in the event of an only irrelevant deviation from the quality agreed or irrelevant impairment of usefulness.
  2. Guarantees for the quality and shelf life of the delivery item shall only be considered as furnished, if we declared the guarantee as such expressly and in writing.
  3. Notice of defect shall be made immediately - and in writing - and is excluded if we do not receive it within 2 weeks after receipt of the delivery. We shall be notified immediately about defects which could not be detected within this period (even with careful inspection), however, 2 weeks after detection at the latest.
  4. If there is a defect in the goods delivered and the cause already existed at the time of the passage of risk, we will at our option rectify the defect free of charge within a reasonable period or remedy the defect by delivery of an item free of defects (subsequent performance). If the buyer rejects this or changes or repairs of the corresponding goods are made, we shall be exempted from the liability for defects.
  5. If rectification of defects fails or if it is not made within a reasonable grace period set by the buyer, the buyer may reduce the purchase price or withdraw from the contract.
  6. a) The buyer shall be responsible for the proper water quality. In this respect the corresponding requirements and guidelines for boiler and feed water have to be observed. In the case of stainless steel storage tanks the water used has to fulfil the values prescribed in the drinking water ordinance.
    b)The buyer must, as far as this is possible and reasonable for him, prove that defects as to quality are caused by faults in material or faulty manufacture of the goods and not by defective mounting. The costs for determining the cause of the defect and other expenses arising within the scope of this obligation shall not be the subject of the warranty.
  7. (1) Damages occurred due to wrong or faulty installation, putting into operation, treatment, operation, maintenance or use of fuels, control devices, types of furnaces and currents or voltages not prescribed or due to choice of incorrect burners or burner settings also do not constitute a claim based on defects.This shall also apply with regard to overload and corrosion damage.
    (2) Liability for usual wear and tear shall be excluded.
    (3)Only the direct buyer shall  be entitled  to assert claims due to defects and such claims  cannot be assigned.
  8. Claims of the buyer for expenses required for the purpose of subsequent performance or reversal of transaction after withdrawal from the contract - transport costs, road costs, labour cost and materials cost, in particular - shall be excluded, if expenses increase because the delivery item was installed at a location difficult to access. The same shall apply if the delivery item was installed outside of the territory of the Federal Republic of Germany.
  9. Recourse claims of the buyer against us, in accordance with section 478 BGB - German Civil Code, (contractor’s recourse) shall only exist to the extent that the buyer did not make an agreement with his customer which goes beyond the legal claims based on defects.
