Conditions

  • 1 General
  1. All contracts concluded with DITUPA GmbH (hereinafter referred to as "we") are subject to the following terms and conditions. They are a legally binding part of all our business transactions and are bindingly accepted by the buyer upon placing the order. No verbal ancillary agreements have been made.
  2. The place of performance and exclusive jurisdiction for all current and future claims and liabilities arising from business relationships is our registered office for us and for contracting parties who are merchants, legal entities under public law, or special funds under public law. German law applies.
  3. If any of the provisions is or becomes legally invalid in whole or in part, the remaining provisions shall not be affected.


  • 2 Offer and conclusion of contract
  1. All offers are subject to change without notice. References to information and images in catalogs and price lists are for illustrative purposes only and do not oblige us to deliver products that are accurate to the image or dimensions. The decisive factor is the customary and standardized quality of the item. If the buyer is not a consumer, any guarantees provided require our written confirmation to be effective. Public statements made by other manufacturers regarding the quality of a purchased item are not binding on us vis-à-vis a buyer who is not a consumer, unless these statements are confirmed by us in writing.
  2. Our product presentations on the Internet do not constitute an offer to conclude a contract, but merely represent an invitation to submit an application.
  3. The buyer submits a binding contractual offer by successfully completing the ordering process provided in our online shop. The order process is completed in the following steps:
  1. Selection of the desired goods or digital goods
  2. Adding products by clicking on the corresponding button (e.g. “Add to cart”, “Add to shopping bag” or similar)
  3. Checking the goods in the shopping cart
  4. Call up the order overview by clicking the corresponding button (e.g. “Continue to checkout”, “Continue to payment”, “To order overview” or similar).
  5. Entering/verifying address and contact details, selecting the payment method, confirming the terms and conditions and cancellation policy
  6. Completion of the order by clicking the “Buy now” button, which represents the binding order

The order confirmation sent by us represents acceptance of the buyer's offer. Upon receipt of the order confirmation, the contract between us and the buyer is concluded.


  • 3 Subject matter of the contract and essential characteristics of the products
  1. In our online shop, the subject of the contract
  1. The sale of goods. The specific goods offered can be found on our product pages.
  2. The sale of digital goods, such as software and media downloads. The specific digital goods offered can be found on our product pages.
  1. The essential characteristics of the goods and digital goods are determined by the item description.
  2. The sale of digital goods is subject to the restrictions stated in the product description or otherwise arising from the circumstances. Unless otherwise agreed in writing, the subject matter of the contract is solely for the private and commercial use of the products, without the right to resale or sublicense.


  • 4 Delivery, delivery delays and acceptance
  1. Delivery deadlines are non-binding unless otherwise agreed in writing. Partial deliveries are permitted. Special circumstances, such as force majeure, strikes, etc., extend the delivery time appropriately and entitle us to withdraw from the contract in whole or in part, provided the buyer is a business. If such disruptions lead to a delay of performance of more than four months, the buyer may withdraw from the contract. Other rights of withdrawal remain unaffected.
  2. The risk of loss or damage to goods ordered by a business owner passes to the buyer upon dispatch, even if partial deliveries are made or freight-free delivery has been agreed. Insurance is only provided upon express request and is at the buyer's expense. Unless specifically instructed, the choice of means and routes of transport is made without guaranteeing the cheapest and fastest method of transport. Failure to meet delivery deadlines does not release the buyer from the obligation to accept the goods.
  3. If we demand compensation for damages due to the buyer's unjustified refusal to accept the goods, this shall amount to 15% of the respective purchase price. The amount of damages shall be higher or lower if we prove greater damage or the buyer proves lesser damage.
  4. For custom-made products, we reserve the right to deliver more or less than 10% of the ordered quantity.


  • 5 Payment, late payment and offsetting
  1. Payment claims are due immediately unless we offer purchase on account.
  2. When purchasing on account, payment must be made within 30 days of the invoice date without deduction to the account specified by the buyer. Payment must be made within this period in such a way that the amount required to settle the invoice is available to us by the due date at the latest.
  3. Representatives or other employees are not authorized to collect payments. Payments to these persons do not release you from your payment obligation to us, unless they have authorization to accept payments.
  4. If partial payments have been agreed, the entire remaining debt – regardless of the due date – becomes due for payment immediately if
  1. The buyer, who is not an entrepreneur, is in default of payment in whole or in part of at least two consecutive instalments and the amount of which he is in default is at least 1/10 of the purchase price or
  2. The buyer, who is an entrepreneur, is in arrears with an instalment for 14 days, has suspended his payments or insolvency proceedings have been opened against his assets.
  1. If the buyer defaults on payment, we are entitled to demand payment of all outstanding invoices arising from the business relationship, cancelling any agreed due dates, with a payment period of 10 days.
  2. Offsetting against purchase price claims is only permitted with undisputed or legally established due claims. The assertion of retention rights and other rights to refuse performance is excluded unless they arise from the same contractual relationship.


  • 6 Warranty and Liability
  1. After collection or delivery, the goods must be checked immediately for accuracy, completeness, and integrity. Any defects must be reported to us – within two days if the buyer is not a consumer. Hidden defects must be reported within one week of discovery. If further defects or damage arise due to failure to report such defects, the warranty is void. The warranty is excluded for used items, custom-made items, performance-enhancing goods, and items not installed by us or an authorized workshop. In the latter case, a current installation manual and invoice from the authorized workshop must be submitted.
  2. Transport damage or missing items must be certified on the consignment note by the railway, otherwise by the driver or the persons involved in unloading, stating their names and addresses.
  3. If a defect is demonstrably identified, we will determine whether to deliver a replacement or repair the goods, unless the buyer is a consumer. In the event of subsequent performance for a buyer who is not a consumer, we will not bear any costs incurred because the item requiring subsequent performance was brought to a location other than the buyer's commercial premises, unless this does not correspond to the intended use of the item. The warranty period for buyers who are not consumers is one year from delivery of the item. If sending the delivery item to the delivery plant is necessary to verify the defectiveness, the subsequent delivery shall be subject to the delivery plant confirming the defectiveness of the delivery item. In such a case, replacement delivery shall only be made against invoice.
  4. The buyer cannot demand compensation in lieu of performance. We are liable for personal injuries caused by simple negligence and for property damage that is typically foreseeable for us and results from the breach of essential contractual obligations. Furthermore, liability is limited to property damage caused by us through gross negligence or intent. To the extent that the damage is covered by insurance taken out by the buyer for the relevant claim, we are only liable for any associated disadvantages to the buyer, e.g., higher insurance premiums or interest losses, until the claim is settled by the insurance company.
  5. The delivery note must be enclosed with all shipments or returns. Any costs incurred due to an unjustified complaint of defects are borne by the buyer.
  6. Obligation to provide information in accordance with Section 36 of the Consumer Dispute Resolution Principles: We are neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board.
  7. Not permitted under the Road Traffic Act.
  • 7 Retention of title
  1. We retain title to the delivered items until all payments under the respective delivery contract have been received. If the buyer is an entrepreneur, the retention of title also applies to the claims (including all balance claims from current accounts and current invoices) that we have against the buyer from ongoing business relationships. Goods to which we have (co-)ownership are hereinafter referred to as "reserved goods."
  2. Combining, processing, transformation, and the like of the delivered items are always carried out for us as the manufacturer, but without any obligation on our part. The buyer then receives a prospective right to the reserved item in the amount of our share of ownership. However, if our (co-)ownership expires as a result, it is agreed that the buyer's (co-)ownership of the unified item shall pass to us in proportion to its value (invoice value).
  3. The buyer may only sell or process reserved goods in the ordinary course of business. If the retention of title expires for reasons other than those stated in Section 6, Paragraph 2, in particular through resale, the buyer hereby assigns to us as security any claims arising therefrom, regardless of whether the buyer sells the goods together with other services or to one or more buyers. The buyer shall immediately notify us of any agreed prohibitions on assignment. At our request, the buyer shall notify the third-party debtors of the assignment, provide us with all information necessary to assert our rights, and hand over all documents to us.
  4. The buyer is obligated to treat the reserved goods with care, to bear any costs incurred, and to store them free of charge. The buyer may not pledge them, assign them as security, or dispose of them in any similar manner. Any such impairment must be reported to us immediately. The buyer, who is a business owner, is obligated to insure the reserved goods against fire and theft at his own expense and to provide us with proof of this upon request by presenting an insurance certificate.
  5. If the buyer defaults on payment or fails to comply with his obligations under the retention of title, we may demand the delivery item from the buyer and, after giving written notice within a reasonable period of time, dispose of it in the best possible way by private sale, offsetting the proceeds from the sale against the purchase price.
  6. If we demand the return of the delivery item, the buyer is obligated to return the delivery item to us immediately, excluding any rights of retention – unless they are based on the delivery contract. In the event of default on payment, the buyer hereby irrevocably authorizes us to immediately collect the reserved goods and to enter his business and storage premises without hindrance for this purpose.
  7. The buyer shall bear all costs associated with the return and disposal of the delivered goods. The disposal costs shall amount to 10% of the disposal proceeds, including VAT, without the need for proof. They may be higher or lower if we prove higher costs or the buyer proves lower costs. The proceeds will be credited to the buyer after deducting the costs and any other claims related to the contract.
  8. If the buyer fails to treat the item in accordance with his obligations under the retention of title or fails to comply with his duty to provide information, maintaining the contract is unreasonable for us. In this case, we may – if necessary after setting a deadline – withdraw from the contract and demand compensation in lieu of performance.
