1. General

These Terms & Conditions apply to all offers, proposals, quotations, agreements and services provided by ZÆT B.V. ("ZÆT", "we", "us" or "our") to clients ("Client", "you" or "your").

ZÆT provides design, engineering, product development and execution services for physical products, mobility products, consumer products and spaces. Our services may include industrial design, mechanical and electrical engineering, prototyping, design for manufacturing, supplier sourcing, manufacturer qualification, production coordination, quality assurance, regulatory support, intellectual property licensing and go-to-market support.

By accepting a quotation, proposal or agreement from ZÆT, the Client agrees to these Terms & Conditions unless explicitly agreed otherwise in writing.

2. Services

The scope of each project will be defined in the applicable quotation, proposal, statement of work or other written agreement.

Depending on the project, ZÆT may provide services including:

• Product and industrial design

• Engineering and technical development

• Frame, structural and composite engineering

• Electrical and IoT development

• Prototyping and validation

• Design for manufacturing

• Supplier and manufacturer sourcing

• Manufacturing and production coordination

• Bill of Materials (BOM) development

• Quality assurance and quality control

• Regulatory and certification support

• Intellectual property licensing

• Go-to-market and launch support

ZÆT will perform the agreed services with reasonable care and professional skill. Unless expressly agreed otherwise, ZÆT does not guarantee a specific commercial, technical or financial outcome.

3. Proposals and Quotations

Unless otherwise stated, quotations and proposals are valid for the period specified in the quotation.

A quotation is based on the information available to ZÆT at the time it is prepared. Changes in project scope, specifications, quantities, materials, suppliers, regulations, timelines or other relevant circumstances may result in additional costs or changes to the agreed schedule.

No work is required to commence until the Client has accepted the applicable quotation or agreement.

4. Project Scope and Changes

The Client is responsible for providing accurate and complete information, specifications, requirements and other materials reasonably required for the project.

Changes requested by the Client after approval of the project scope may affect the cost, schedule and deliverables.

ZÆT will inform the Client where a requested change is expected to have a material impact. Additional work will be charged at the agreed project rate or, where no rate has been agreed, at ZÆT's applicable hourly or daily rate.

5. Client Responsibilities

The Client remains responsible for decisions concerning the commercialisation, production and use of the final product unless otherwise agreed in writing.

The Client is responsible for ensuring that the final product complies with all laws, regulations, standards and certification requirements applicable to the markets in which the product is sold or used.

Where ZÆT provides regulatory, certification or compliance support, such support does not constitute a guarantee that a product will obtain or retain a particular certification or regulatory approval.

6. Suppliers and Manufacturers

ZÆT may introduce, recommend or coordinate suppliers, manufacturers, contractors and other third parties as part of a project.

Unless otherwise agreed in writing, these third parties remain independent parties and are not employees, agents or subcontractors of ZÆT.

ZÆT is not responsible for delays, defects, failures, price changes or other acts or omissions of third-party suppliers or manufacturers, except to the extent caused by ZÆT's own proven negligence or failure to perform its agreed responsibilities.

Where ZÆT coordinates production or quality control, this does not transfer the manufacturer's responsibility for the quality, safety or regulatory compliance of manufactured products to ZÆT.

7. Deliverables and Approval

Project deliverables may include drawings, CAD files, engineering documentation, specifications, prototypes, BOMs, reports, design files, concepts or other materials as defined in the project agreement.

The Client is responsible for reviewing and approving deliverables within a reasonable period.

Once a deliverable has been approved by the Client, subsequent changes resulting from that approval may be treated as additional work.

Unless expressly included in the agreed scope, source files, editable design files, manufacturing files or other working files are not automatically included in a final deliverable.

8. Intellectual Property

Each party retains ownership of intellectual property it owned or developed independently before the project.

Unless otherwise agreed in writing, ZÆT retains ownership of its pre-existing know-how, methodologies, tools, templates, processes, concepts and other intellectual property used in performing the services.

Ownership or licensing of project-specific intellectual property will be determined by the applicable quotation, project agreement or separate written agreement.

Payment for a project does not automatically transfer all intellectual property rights from ZÆT to the Client unless such transfer has been expressly agreed in writing.

Where intellectual property is licensed rather than transferred, the scope, duration, territory and commercial conditions of the licence will be defined in the applicable agreement.

9. Confidentiality

Both parties agree to keep confidential information received from the other party confidential and to use such information only for the purposes of the relevant project or business relationship.

Confidential information does not include information that:

• is publicly available without breach of confidentiality;

• was already lawfully known to the receiving party;

• is independently developed without use of confidential information; or

• must be disclosed by law or competent authority.

Confidentiality obligations will continue after termination of the project for as long as the information remains confidential.

10. Fees and Payment

Fees, payment terms and applicable expenses will be specified in the quotation or project agreement.

Unless otherwise agreed, invoices are payable within 14 days of the invoice date.

If payment is not received by the due date, ZÆT may suspend work until outstanding amounts have been paid.

Reasonable costs incurred by ZÆT in connection with the project, including approved travel, prototypes, materials, testing, shipping, tooling, certification and third-party services, may be charged separately where not included in the agreed project fee.

All amounts are exclusive of VAT and other applicable taxes unless explicitly stated otherwise.

11. Prototypes, Testing and Production

Prototypes, samples and test products are intended for development and validation purposes unless expressly approved for commercial use.

A prototype or development sample should not be considered evidence that a final production product is safe, certified, compliant or suitable for commercial sale.

The Client is responsible for final product validation, certification and approval before commercial production or market release unless ZÆT has expressly accepted these responsibilities in writing.

12. Timelines

Project schedules are estimates unless a specific deadline has been expressly agreed in writing.

Delays caused by the Client, suppliers, manufacturers, testing facilities, certification bodies, regulatory authorities, shipping companies or other third parties may affect the project schedule.

ZÆT will make reasonable efforts to communicate material delays and their expected impact.

13. Cancellation and Termination

Either party may terminate a project in accordance with the terms of the applicable project agreement.

If a Client cancels a project after work has commenced, the Client remains responsible for payment for work already performed, approved expenses, committed third-party costs and other non-cancellable project costs.

ZÆT may suspend or terminate services if the Client materially breaches the agreement, fails to make required payments or otherwise prevents ZÆT from reasonably performing the agreed services.

14. Liability

ZÆT will only be liable for direct damage resulting from an attributable failure to perform its contractual obligations, to the extent permitted by applicable law.

ZÆT is not liable for indirect damage, consequential damage, loss of profit, loss of revenue, loss of production, loss of business opportunities, loss of data or reputational damage unless such exclusion is not permitted under applicable law.

To the maximum extent permitted by law, ZÆT's total liability in relation to a project will not exceed the total amount actually paid to ZÆT by the Client for the relevant project during the twelve months preceding the event giving rise to the claim.

Nothing in these Terms & Conditions excludes liability where such exclusion is prohibited by mandatory law.

15. Product Responsibility

The Client remains responsible for the final product placed on the market, including its safety, regulatory compliance, instructions, warnings, labelling, certification and suitability for its intended use, unless these responsibilities have expressly been assigned to ZÆT in writing.

Design or engineering services provided by ZÆT do not constitute a transfer of the manufacturer's or brand owner's legal responsibilities.

16. Force Majeure

ZÆT will not be liable for failure or delay caused by circumstances beyond its reasonable control, including but not limited to natural disasters, war, pandemics, government actions, supply-chain disruptions, transportation disruptions, strikes, material shortages, energy shortages, cyber incidents or failures of third-party suppliers.

Where such circumstances materially affect a project, the parties will discuss reasonable adjustments to the project scope, timeline and costs.

17. Website Content

The information published on the ZÆT website is provided for general information purposes.

While ZÆT aims to keep website information accurate and up to date, we do not guarantee that all information is complete, accurate or current.

18. Third-Party Websites

The ZÆT website may contain links to websites or services operated by third parties. ZÆT is not responsible for the content, availability, security or privacy practices of third-party websites.

19. Privacy

Personal information submitted through the ZÆT website or in connection with our services will be handled in accordance with our Privacy Policy and applicable data protection legislation.

20. Applicable Law

These Terms & Conditions and agreements between ZÆT and the Client are governed by the laws of the Netherlands, unless mandatory applicable law requires otherwise or the parties have expressly agreed to another governing law.

21. Disputes

The parties will first attempt to resolve any dispute through good-faith consultation.

If a dispute cannot be resolved amicably, it will be submitted to the competent court in the Netherlands, subject to any mandatory jurisdiction rules applicable to the parties.

22. Amendments

ZÆT may update these Terms & Conditions from time to time.

The version applicable to a particular project will be the version agreed or incorporated into the relevant quotation or project agreement.

The latest version applicable to the use of the ZÆT website will be published on this page.
