GENERAL TERMS OF SALES AND CONDITIONS OF CONTRACT
All services or analyses will be done exclusively due to the following general terms of sales and conditions
of contracts – if not otherwise agreed.
Prices
The rates in the pricelist do not include the statutory value-added tax.
Price reductions for sample series or long-term contracts will be arranged with the customer for special
agreements. Express services will be charged by a surcharge of 50%. There will be an extra charge for special
sample treatments.
Prices are subject to change without notice – except for written short-term offers.
Delivery dates
Delivery dates for standard analyses are usually 8-10 working days, for express analyses 1-5 working days.
The indication of delivery date is not guaranteed. The delivery date starts after receiving the sample and clarification
of all relevant information.
We shall not be liable to the customer for any delays in performance or any non-performance of its obligations
as a result of causes beyond its control (which for the avoidance of doubts shall include, but not be
limited to, acts of God, strike, lock-out, government order, non-availability of equipment or parts, power or
other utilities failures etc.) and also if they affect our suppliers or subcontractors.
Claim for damages due to noncompliance of a delivery date will be excluded in either case.
Terms of payment
Payment of all invoices is due strictly within 30 days of the invoice date.
Methodology
The customer can not demand any analyses instructions. Details of the uncertainty of measurement for the
parameters will be provided on request.
Liability
For the results of analyses as well as eventually resulting damages, the liability will be expressly excluded
(within the legal requirements), also those for auxiliary persons.
A special risk (e.g. explosive, toxic, carcinogenic etc.) of materials send for analyses has to be labeled as
well as written in the order-form. Otherwise the client will be responsible for damage to persons or property
resulting thereof.
Samples and archival storage
Volume and kind of service are in accordance to the written request.
The requester is responsible for the property and conditions of the delivered samples.
Rest of non perishable samples will be stored for 3 months, perishable samples will be stored for 5 working
days. Data of analyses will be retained for 5 years.
Duty of confidentiality
Results of analyses and information regarding product and customer will be treated as strictly confidential.
Without the written permission of the customer, certificates of analyses will neither be sent by internet nor to
third parties.
Cancellation
A cancellation of an analyses request has to be done in written form by the requestor. The requester will be
charged according to current rates for the efforts and working time until the cancellation.
Placing of sub-orders
The contractor is authorised to perform services by third parties. If necessary due to QA-regulations or
certification guidelines, the transfer to third parties will be carried out after consulting the client.
Customer feedback
Customer feedback will be registered and handled within our quality management system.
Place of jurisdiction and applicable law
The Swiss law will be exclusively adopted. Place of jurisdiction is exclusively the domicile of the contractor.
