Compliance with prototypes
If the client wishes to return the received parts due to non-conformity, they must notify us within TWO working days following receipt. Additionally, they must attach a non-conformity report specifying the reasons for the return.
Once the non-conformity notification is received, the parts will be collected to allow for a verification of the non-conformity at our facilities. If the issue is confirmed, the parts will be repaired or remade if repair is not possible.
Packaging and shipping
Unless otherwise requested, parts are shipped via NACEX the next working day, prepaid, with the invoice attached.
Unless previously requested, packaging will be done in a cardboard box.
The price refers to delivery ex-works, unless other terms are agreed upon. If the buyer requires a delivery term different from ex-works for the products, the buyer must contact the Seller to detail their requirements. The Seller will accept, at their sole discretion, to adapt to the buyer's requirements, including, among others, transport insurance, the transport method (the Seller reserves the right to vary the mode of transport if any regulation or other relevant considerations so require) and any special packaging requirements. To avoid any doubt, all shipping and packaging costs according to the buyer's requirements that exceed standard ex-works packaging will be borne by the buyer, unless both parties agree otherwise.
Shipping costs will be calculated during the ordering process based on the shipping address.
Product shipping can be made to any country.
Lead time
Delivery time will be counted from the next working day following receipt of the payment associated with the work request.
Quotes issued by the Seller will include an estimated delivery date, calculated based on input data. The lead time generated by the online ordering system constitutes a mere preliminary indication of the delivery date and does not commit the Seller in any way. The estimated delivery time is calculated based on working conditions existing at the time of formalizing the agreement and depends on punctuality in the delivery of materials requested by the Seller for the execution of the work. In case of delays not attributable to the Seller, resulting from a change in the aforementioned working conditions or due to delay in the supply of materials requested for the execution of the work, the lead time will be extended as necessary, the Seller being exempt from any liability for such delay.
If the client does not receive the ordered parts, they must notify us within five days following the scheduled receipt date.
Quotes
A quote is only valid for the 3D model in CAD on which it is based. Any change made to the 3D model in CAD requires an updated quote.
Quotes have a validity of 30 days; after that date, prices may vary without prior notice.
Prices and Payment Terms
All prices are quoted and payments will be made in €. Payment can be made with Visa, MasterCard, PayPal or Bank Transfer.
Independent parts of a quote may be invoiced separately. The Seller reserves the right to decline execution of subsequent components of a quote, or of subsequent quotes, or to cancel a delivery, as long as there are outstanding overdue invoices.
