General terms and conditions


Orders will be honoured only if customers have accepted these General Terms and Conditions (GTC). Orders placed via the online shop are confirmed to the customer via e-mail. This confirmation is needed to finalize a contract between the customer and Wipf AG. Wipf AG is entitled to reject an order. The customer may not amend orders that have been confirmed. The minimum order quantity is 10,000 units (1 cardboard box).

Despite confirmation, a product that has been ordered may not be on stock. In such cases, Wipf AG is entitled to cancel the order. The customer will be notified by e-mail. In such cases, no belated delivery shall take place. The customer’s payment shall be refunded. If several products were ordered and one of the products cannot be delivered, the customer may not cancel the purchase of the other products. No liability can be accepted for non-delivery or delayed delivery.

If the customer identifies a defect, we must be notified as quickly as possible. Replacements are possible only if the shipped goods are damaged or defective.

Prices and payment

The ex-works prices published at are valid and do not include packaging and freight. All prices are indicated in Swiss francs and include VAT. Prices stated in EUR or USD will vary depending on daily exchange rates and are posted exclusive of VAT. Payments can be effected via credit card, Twint, advance remittance and against invoice. In the event that a payment is delayed, Wipf AG is entitled to contract third parties with the collection of outstanding amounts and to assign the rights to accounts receivable to domestic or foreign third parties. Unless explicitly stated otherwise, prices are subject to change and are based on current cost factors. If cost factor changes occur up to the delivery date, for instance due to price increases for raw materials, wages, or energy price increases, we reserve the right to increase or decrease prices in accordance with such changes, in which case the purchaser shall be notified in advance. We will apprise the purchaser at least four weeks in advance if such price changes are imminent. In the event that prices are increased, the purchaser shall be entitled to cancel the order as per the date on which the price increase becomes effective. The prices that are valid on the delivery date shall apply to orders for which no specific prices have been agreed.


The guarantee period for WICOVALVE® products is generally three years starting on the manufacturing/production date. The guarantee does not cover damage incurred at a later date due to improper handling or storage shortcomings. If the customer identifies a defect, we must be notified as quickly as possible. Wipf AG may ask for the defective goods to be returned.
