General Sales Conditions

1. SCOPE

These general terms and conditions shall be applicable to all our sales contracts unless specified otherwise. Purchaser’s general terms and conditions are hereby expressly excluded, regardless of the point in time in which they are sent to us. These general terms and conditions shall also apply to all future sales made to Purchaser.

Any provision included in Purchaser’s documentation subsequent to our commercial offer or purchase order which modifies these general terms and conditions shall be considered null and void, unless specifically agreed in writing by us.
These general terms and conditions have been provided to the Purchaser in the preparation of the sale of the product to enable him to take notice of the same.

2. COMMERCIAL OFFERS & ORDERS

2.1 Our commercial offers are not binding and may be changed at any time, even if they include a period of validity. Any amendment to a commercial offer made by the Purchaser shall not be valid unless expressly accepted by us in writing.

2.2 Orders, whether sent to us or via our agents or brokers, shall not be considered to have been accepted unless expressly confirmed in writing by us. The acknowledgement of receipt of an order is not considered as an acceptance of the same.

3. PRICE & TERMS OF PAYMENT

3.1 To the extent permissible by law, if exceptional circumstances, occurred between the acceptance of the order and the delivery of the goods, affect the economic balance of the sales contract, price and payment conditions may be subject to change in the exact measure necessary to reinstate the economic balance. In such a case, we shall notify the Purchaser, who will then be able to withdraw its order within seven (7) days after being notified of the new price. If the Purchaser fails to do so within this period, the new conditions shall be deemed accepted by the Purchaser and shall apply to the sale.

3.2 Except as indicated in writing by us:
– Prices are exclusive of VAT and any other taxes;
– Payments shall be made at thirty (30) days from the date of invoicing.

3.3 Non payment of any invoice shall be considered a fundamental breach by the Purchaser entitling us to suspend any further delivery or to consider the contract terminated immediately by reason of the Purchaser’s default. Late payment fees are due automatically, without the necessity of a reminder and without prejudice to any other damages, from the day following the date or the end of the period for payment indicated on the invoice or fixed in the contract. The interest rate will be equal to the rate applied by the European Central Bank to its most recent refinancing operation plus ten percent (10%). In addition, as compensation for recovery costs and pursuant to the relevant European Directive on combating late payment in commercial transactions, a fixed sum as well as any additional costs of the recovery of the original invoice (to the extent reasonably incurred), shall be payable.

In the event there has been a substantial reduction of the solvency ratio of the Purchaser, we reserve the right to require payment guarantees from the Purchaser or, as an alternative, to terminate any outstanding orders.
