1.1 The contracting party for all deliveries and services initiated through nanoz.ai is TSR Messtechnik AG, Ebnatstrasse 164, CH-8207 Schaffhausen, UID CHE-188.494.819 (“we” or “TSR”). The website nanoz.ai is operated by it.
1.2 Our offering is directed exclusively at entrepreneurs — natural or legal persons and partnerships with legal capacity acting, at the time of contract, in the exercise of their commercial or independent professional activity. No contracts are concluded with consumers. By placing an order the buyer confirms that they are acting as an entrepreneur and, on request, provides evidence by stating their commercial register or VAT identification number. We reject orders from consumers.
1.3 There is no online ordering process on nanoz.ai. The website provides information about our products; enquiries lead to a quotation by e-mail or post. A contract comes into being when we expressly confirm an order or deliver the goods.
1.4 Deviating terms of the buyer apply only where we have expressly agreed to them in writing. A mere reference to the buyer's own purchasing conditions is not sufficient.
1.5 Statements in brochures, catalogues and technical documents are not binding without express written agreement. Only the applicable datasheet and our order confirmation are binding.
1.6 For individually manufactured special tooling the buyer is responsible for the accuracy of their specifications — drawings, dimensions and the like. Such specifications must always be submitted in writing. Special tooling is excluded from exchange.
2.1 Unless expressly agreed otherwise, the prices stated in our quotation apply.
2.2 Discounts reflected in net prices apply from a minimum goods value of CHF 100, excluding shipping and packaging costs and excluding VAT.
2.3 Shipping and packaging are invoiced separately. Depending on the agreed Incoterms or shipping options, additional costs such as customs duties, import taxes or transport insurance may arise.
2.4 All prices are exclusive of statutory VAT at the applicable rate, where such tax arises. For intra-Community supplies and exports the relevant tax provisions apply; the buyer provides the information and evidence required for this.
2.5 Invoices are to be checked within a reasonable period. Objections to invoicing raised after the payment deadline can no longer be taken into account.
3.1 Payment is made against invoice, in advance, or by another means stated in the quotation.
3.2 Where goods are delivered against invoice, the purchase price falls due within 30 days of the invoice date without deduction. In the event of late payment we are entitled to charge statutory default interest and a reasonable fee for each reminder, and to assign outstanding claims to a debt collection agency, which may charge additional fees.
3.3 Goods delivered remain our property until paid for in full.
3.4 Set-off against disputed counterclaims, or counterclaims not established by a final judgment, is excluded.
4.1 The minimum order value is CHF 30, excluding shipping and packaging costs and excluding VAT. We reserve the right to make partial deliveries where this serves efficient handling and is reasonable for the buyer. Transport damage must be reported to the carrier without delay and notified to us.
4.2 Necessary or prescribed packaging is not taken back unless expressly noted otherwise.
4.3 Benefit and risk pass to the buyer on handover of the delivery to the buyer or to the carrier; deviating Incoterms remain reserved.
4.4 If the goods ordered are no longer available, the buyer may withdraw from the order or accept a substitute article proposed by us, which may differ in quality and price. Payments already made are refunded without delay in that case.
4.5 Export control. The export of certain products, including software and documentation, may be subject to restrictions and to authorisation — depending on their nature, intended use or destination. The buyer undertakes to strictly observe all applicable export control and sanctions provisions, in particular those of Switzerland, the European Union, its member states and the United States. Passing goods to third parties or reselling them in breach of those provisions is prohibited. The buyer indemnifies us against claims arising from a breach of this obligation.
5.1 We voluntarily grant a right of return of 14 calendar days from delivery. The goods must be returned unused, undamaged, complete and in their original packaging.
5.2 Individually manufactured articles, and articles not held in stock but procured specifically for the buyer, are excluded.
5.3 Returns are made at the buyer's cost and risk and must be agreed with us in advance.
5.4 After receipt and inspection of the goods we refund or credit payments already received.
6.1 The warranty period is 12 months from delivery.
6.2 We warrant that the goods are free from defects in material and workmanship and conform to the agreed specifications at the passing of risk. For goods not manufactured by us, the manufacturer's warranty terms apply in addition.
6.3 The buyer inspects each delivery immediately on receipt for external damage, incorrect delivery and shortfalls, and notifies complaints in writing within three working days. Defects appearing later must be notified without delay after discovery. If notification is omitted, the goods are deemed approved.
6.4 Where a defect covered by the warranty exists, we or the manufacturer will, at our discretion, repair or replace the goods. If both fail twice, the buyer may reduce the purchase price or withdraw from the contract.
6.5 If no defect can be established, or a defect is not covered by the warranty, we may invoice the costs of inspection and shipping.
6.6 Fitness for purpose. Our sensors are components intended for integration. The characteristic values in the datasheet apply under defined test conditions; behaviour in the application depends on mounting, flow, humidity, temperature and enclosure design. Assessing fitness for the specific intended use is the buyer's responsibility. Use in safety-critical applications requires a separate written agreement.
6.7 We carry out repair and service work against reimbursement of costs. Where a cost estimate is expressly requested, we charge the cost of preparing it plus a handling surcharge even if the order is not placed.
7.1 We are liable without limitation for intent and gross negligence, for damage arising from injury to life, body or health, under the mandatory provisions of product liability law, and to the extent of any guarantee we have given.
7.2 In the event of slightly negligent breach of a material contractual obligation — an obligation whose fulfilment makes proper performance of the contract possible in the first place and on whose observance the buyer may regularly rely — our liability is limited to the foreseeable damage typical of the contract at the time it was concluded.
7.3 Liability is otherwise excluded. This applies in particular to loss of production, loss of use, loss of profit, third-party claims and other indirect and consequential damage.
7.4 Any exclusion of liability for unlawful intent and gross negligence is void under Art. 100 CO; clause 7.1 therefore prevails over clause 7.3 to that extent.
8.1 We reserve all rights of ownership and copyright in datasheets, drawings, software and other documents provided. Passing them to third parties requires our written consent.
8.2 The NANOZ trade mark and the product designation NZGS 2 are marks of their respective owners. MoxAi is a mark of TSR Messtechnik AG. The contract confers no right to use them.
8.3 The parties treat information designated as confidential in confidence and use it only for the purposes of the contract. This obligation continues for five years after the contract ends.
9.1 Data protection. We treat personal data confidentially and with due care. Details are set out in our privacy policy.
9.2 Language of the contract is German. Translations serve comprehension; in the event of discrepancies the German version prevails.
9.3 Contract text. As there is no automated ordering process on nanoz.ai, we do not store a contract text in a customer account. The buyer receives the order confirmation, the invoice and these terms in text form by e-mail or post.
9.4 Amendments. We reserve the right to adapt these terms for future contracts. For a contract already concluded, the version published at the time of conclusion applies.
9.5 Severability. If a provision of these terms or of the supply contract is invalid, the validity of the remaining provisions is unaffected. The invalid provision is replaced by a valid one that comes closest to its economic purpose.
9.6 Governing law. This contract and the entire legal relationship between the parties are governed by Swiss law, excluding the United Nations Convention on Contracts for the International Sale of Goods (CISG) and excluding conflict-of-law rules.
9.7 Place of performance and jurisdiction. The place of performance is Schaffhausen. The exclusive place of jurisdiction for all disputes arising out of or in connection with this contract is Schaffhausen, Switzerland. We reserve the right to bring proceedings against the buyer at its registered office as well.
