General Terms and Conditions

Catalysis Additive Tooling GmbH, Steinhügel 112 J, D-58455 Witten, Germany · As of 09/2026

§ 1 Scope

These General Terms and Conditions apply to all offers, deliveries and services of Catalysis Additive Tooling GmbH, Witten, Germany („Catalysis“) towards entrepreneurs within the meaning of § 14 German Civil Code (BGB), legal entities under public law and special funds under public law. Conflicting or deviating terms of the customer shall not become part of the contract, even if Catalysis does not expressly object to them.

§ 2 Offers and Conclusion of Contract

Our offers are subject to change and non-binding. The contract is concluded upon our order confirmation in text form or upon execution of the delivery. The order confirmation is decisive for the scope of delivery. We reserve title and copyright in calculations, design data, drawings and other documents.

§ 3 Design Approval

Production is based on the tool design approved by the customer. The customer checks the approval data for correctness and suitability for its application; production starts upon approval. Subsequent changes are charged on a time-and-material basis.

§ 4 Manufacturing Process and Tolerances

Our tools are produced by 3D sand printing (binder jetting) with subsequent infiltration and surface finishing. Unless expressly agreed otherwise, the general tolerances according to DIN ISO 2768-c apply to dimensions without individual tolerance indication. This tolerance level does not correspond to that of milled aluminium tools. Tighter tolerances on individual functional surfaces are possible by mechanical rework upon prior agreement. The aforementioned tolerances refer to the tool contour; dimensional accuracy, warpage and shrinkage of the parts produced with the tool depend on the customer’s processing parameters and are not part of the agreed quality. Process-typical characteristics (e.g. surface roughness, layer structure, porosity of the infiltrated sand body) do not constitute a defect.

§ 5 Prices and Payment

All prices are net plus statutory VAT, ex works Witten including packaging unless stated otherwise. A base plate is only part of the scope of delivery if it is listed in the order confirmation. Unless otherwise agreed, invoices are payable within 30 days from the invoice date without deduction. Set-off and retention are only permitted with undisputed or legally established claims.

§ 6 Delivery and Transfer of Risk

Delivery periods start upon design approval pursuant to § 3 and are subject to correct and timely delivery to us by our own suppliers. Unless a delivery date has been expressly agreed as binding, it is an estimated date. Partial deliveries are permitted to a reasonable extent. Risk passes to the customer upon handover to the carrier, at the latest when the goods leave our works (EXW Witten, Incoterms 2020, including packaging).

§ 7 Retention of Title

Delivered goods remain our property until full payment of all claims arising from the business relationship.

§ 8 Handling, Storage and Limits of Use

If a base plate is part of the scope of delivery, dimensional stability and vacuum distribution are only ensured in the assembled condition; in that case the tool must not be dismounted. Without a base plate, the mounting, assembly and vacuum connection are the customer’s responsibility.

The handling and storage instructions supplied with the tool apply to transport, assembly, operation and storage. Claims for defects do not exist insofar as the damage results from dismounting, modification, impact or drop loads, impermissible point loads (e.g. striking, prying, setting down on edges), improper transport, or storage or use contrary to the handling and storage instructions.

Normal wear in production use does not constitute a defect. A specific tool life is only owed if it has been expressly agreed in the order confirmation. Information on achievable part quantities in data sheets, catalogues or advertising material reflects empirical values and constitutes neither an agreed quality nor a guarantee.

§ 9 Inspection and Notification Obligations, Warranty

The commercial inspection and notification obligations (§ 377 German Commercial Code, HGB) apply; obvious defects must be notified in text form within 10 working days of delivery. In the case of justified notices of defects, we shall, at our option, provide subsequent performance by rectification or replacement delivery. If subsequent performance fails, the customer is entitled to its statutory rights. The limitation period for claims for defects is 12 months from delivery; this does not affect claims based on intent, gross negligence, injury to life, body or health, fraudulent concealment of a defect, or a guarantee assumed by us.

§ 10 Liability

(1) We are liable without limitation for damage resulting from injury to life, body or health, for damage caused by intent or gross negligence, in the case of fraudulent concealment of a defect, and to the extent of a guarantee assumed by us. Liability under the German Product Liability Act (Produkthaftungsgesetz) remains unaffected.

(2) In the case of a slightly negligent breach of material contractual obligations – i.e. obligations whose fulfilment is essential for the proper performance of the contract and on whose observance the customer may regularly rely – our liability is limited to compensation for the foreseeable damage typical of the contract. Otherwise, liability for slight negligence is excluded.

(3) The above limitations of liability apply to all bases of claim, in particular also to claims in tort, and to the same extent in favour of our legal representatives, employees and vicarious agents.

(4) Before starting series production, the customer will sample the tool and check the first parts produced with it for dimensional accuracy and function. § 254 BGB (contributory negligence) remains unaffected.

§ 11 Confidentiality and Intellectual Property

We treat data and documents provided by the customer confidentially and use them only for the performance of the contract. The customer warrants that production according to its specifications does not infringe any third-party rights.

§ 12 Final Provisions

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). Place of performance is Witten; place of jurisdiction is Bochum, Germany. Should individual provisions be invalid, the validity of the remaining provisions remains unaffected. The German version of these General Terms and Conditions is authoritative.
