We will be entitled to the full range of set-off and retention rights provided by law.

§ 7 Delivery and Passing of Risk

(1) The delivery times shown for products or services on the websites and in the confirmation mail are intended as a rough guide as to when delivery will occur.

(2) We will be deemed to have complied with the agreed delivery time if the goods were dispatched from our warehouse on time. Compliance with the delivery time presupposes that the Customer and trenzyme have clarified all commercial and technical issues and that the Customer has fulfilled all of its duties.

(3) If the Customer fails to accept delivery or if it intentionally or negligently breaches other duties to cooperate, we will be entitled to demand compensation for the resulting loss or damage which we have incurred, including compensation for any additional expenses. We reserve the right to assert further claims.

(4) If the Customer fails to accept delivery or if it intentionally or negligently breaches other duties to cooperate, the risk of accidental loss or deterioration of the goods, in deviation from subsection (4), will pass to the Customer at the time of the failure to accept delivery or at the time of its breach of other duties.

(5) Where a force majeure event occurs, we will be entitled to suspend delivery of the goods for the duration of the impediment and for a reasonable start-up period thereafter or to rescind the contract wholly or in part due to the unperformed portion. Strikes, lockouts as well as unforeseen and unavoidable circumstances, e.g. business disruptions, will be the equivalent of force majeure events if they make it impossible for us to deliver on time in spite of our making a reasonable effort to do so. We have the burden of proving that this is the case. The same applies if the aforementioned impediments occur during a delay or affect our subcontractor. The Customer may request us to notify it within a period of two weeks as to whether we wish to rescind the contract or deliver the goods within a reasonable grace period. If we fail to respond, the Customer may rescind the unperformed part of the contract. In the event that a force majeure event, as described above, occurs, we will notify the Customer without delay.

§ 8 Cancellation by the Customer

(1) The Customer has the right to cancel the order within the following cancellation period: the cancellation period starts with the receipt of the order confirmation from trenzyme and ends with the earlier of:

(i) the dispatch of the goods from the supplier or

(ii) the expiry of 24 hours.

The Customer is not, however, entitled to any further right of withdrawal.

(2) In cases where cancellation occurs later than defined in (1), trenzyme may take back the goods on a voluntary basis and at its sole discretion and will be entitled to issue an invoice for 30% of the price of the goods as a re-stocking fee plus any transport costs and any customs duties. In this case, the Customer will not, however, under any circumstances be entitled to cancel the contract.

(3) Where the Customer has already received the goods and if trenzyme agrees to take back the goods as a gesture of goodwill, the goods must be returned in their original packaging or other appropriate packaging and with the necessary cooling at the expense of the customer. In the event of cancellation, trenzyme will at no time be responsible for the risk of loss or damage during shipping. The Customer will be charged for returned goods which trenzyme, in the exercise of its due discretion, classifies as defective due to incorrect or interrupted cooling or for any other reasons. As a rule, goods returned after 90 days will not be accepted.

§ 9 Warranties

(1) Due to the nature of our products, information about their characteristics (ingredients, quantities, technical data etc.) can only be treated as approximate values. The same applies to information provided by us and our providers in the product datasheets. Minimal deviations that are customary in the industry will not entitle the Customer to any warranty claims.

(2) Insofar as this is feasible in the ordinary course of business, the Customer will check the product supplied immediately after delivery by trenzyme to see whether it is of the quality that is specified in the product description. The Customer will notify us of any defects immediately. If the Customer does not notify us of any defects, the goods will be deemed accepted unless the defect was such that it could not be discovered at the time of the examination. If the Customer uses or processes the goods, it will also be deemed to have accepted them as being in conformity with the contract and it will be excluded from making any warranty claims unless the products’ defects could only be determined through using/processing them.

(3) In the case of a complaint, we will be entitled to request a data report on measurement results to enable us to check the complaint. Where a complaint is justified, we will only be obliged to supply replacement goods that are free from defects. In such cases, trenzyme can arrange for the goods to be collected. If the goods will be collected, Customer must ensure that the goods are packaged in a way that is suitable for transporting them.

(4) If we do not comply with this obligation to supply replacement goods pursuant to subsection (3) within a reasonable deadline or if we fail to replace the goods despite repeated attempts to do so, the Customer will be entitled to reduce the purchase price or to rescind the contract. The provisions of § 10 govern any further claims that the Customer may have against us, in particular claims for reimbursement of expenses or damages for defects or damages for consequential damage caused by defects.

(5) The statutory limitation period for notification of defects expires 12 months from the date that the risk passes.

(6) Our liability under any warranties as to the characteristics or durability of the goods and our liability for fraudulent concealment of a defect, intentional wrongdoing, gross negligence or injury to life, body or health remains unaffected by the aforegoing provisions. In these cases, the statutory provisions/statutory warranty periods apply.

§ 10 Liability

(1) In all cases in which we are contractually or legally bound to pay damages or reimburse expenses, we will only be liable to the extent that we or our legal representatives or vicarious agents are guilty of intentional wrongdoing or gross negligence or cause injury to life, limb or health. The foregoing is without prejudice to our strict liability pursuant to the Product Liability Act (Produkthaftungsgesetz). In addition, the foregoing is without prejudice to our liability for any intentional or negligent breach of a material contractual obligation (= a duty whose fulfillment is of the very essence for the proper implementation of the contract and upon whose fulfillment the contractual partner may regularly rely); thus, except in cases covered by the first and second sentences, our liability will be limited to the usual and foreseeable damage. The aforementioned provision does not reverse the burden of proof in a way which would be detrimental to the Customer’s interests.

(2) In particular, trenzyme will not be liable if products that it sells are used for purposes other than those outlined in the product datasheet or if the Customer does not comply with other guidelines in the product datasheet or the material safety data sheet.

(3) To the extent to which our liability for damages is excluded or limited, this also applies in respect of the personal liability for damages of our employees, workers, staff, representatives and agents.

§ 11 Use of Delivered Products, Consulting

(1) By placing its order, the Customer confirms that it will only use the acquired products for research and development purposes. trenzyme does not subject its products to regulatory or other testing, nor does it validate them for clinical, therapeutic or diagnostic use or for safety and efficacy.
The end user must be familiar with the procedures for handling these products and the statutory rules for doing so. The products may only be used by trained personnel in laboratories equipped for this purpose and may not be resold to private individuals.

(2) The Customer shall, in relation to its use of the services, any products and any results, information, data and/or analysis provided as part of the services comply with all applicable laws and obtain any consents from any body or authority which may be required. Furthermore, the Customer agrees to ensure that the acquired products are used in accordance with the relevant use and safety regulations and are properly disposed of.

(3) Any use of the purchased substances contrary to ethical, legal, or political standards is prohibited.

(4) If not otherwise stated, all plasmids, cell lines, microorganisms and proteins are delivered on an “AS IS” basis for Research Use Only (RUO) and is understood to be experimental in nature.

(5) In accordance with German law (Biostoffverordnung) and if not otherwise stated in the documentation, the plasmid, cell line or microorganism is allocated to Risk Group 1. The Customer recognizes that the classification may be different in other countries and is obliged to check the classification in his country.

The purchaser agrees to comply with all applicable laws and regulations in the use, maintenance and disposal of the cell line or microorganism.

(6) Any consulting provided by us must be considered as non-binding advice from us. It does not release the Customer from the duty to carry out its own examination of the goods to ensure that they are suitable for its intended procedures and purposes. Furthermore, it does not release the Customer from its own duty of care. The Customer must comply with the necessary duty of care even where the goods do not carry a clear hazard symbol. The limitation on liability pursuant to § 10 applies.


§ 12 Retention of Title

(1) We reserve title to the goods delivered until we have received all payments under the contract. Furthermore, we will remain the owner of the goods until all of our claims against the Customer have been satisfied; this also applies where the purchase price for specifically designated claims has been paid. In the case of a current account, the retention of title to the goods delivered (goods subject to a retention of title clause) will be regarded as security for the balance owed to us.

(2) Goods which are subject to a retention of title clause may not be assigned as security, sold to obtain cover or pledged. The Customer must notify us without delay if a third party attaches or seizes goods subject to our retention of title. Any resulting costs of intervention will, in any event, be borne by the Customer except where a third party is responsible for them.

§ 13 Privacy Policy

(1) trenzyme will ensure that any Customer data will be processed, stored, transmitted, and used only in accordance with the German Data Protection Act. For more information, please check our Privacy Policy.
