We hope this message finds you well and motivated to continue our collaboration.

First and foremost, we would like to express our sincere gratitude for the business relationship we have maintained so far. Your commitment and quality in providing products/services have been vital to the success of our organization.

Today, we are writing to you with a special and highly important purpose. We wish to share our company’s commitment to ISO 9001 Quality Management and our ongoing dedication to implementing ISO 14001 Environmental Management.

Aligned with the principles of continuous improvement that guide our Quality Management System under ISO 9001, we inform you that, as part of our internal monitoring and control process, we conduct a periodic evaluation of suppliers. This annual review, carried out by the person responsible for supplier management, aims to assess various aspects related to the delivery of products and/or services. Among the criteria considered are:

• The quality and/or sustainability of the products/services supplied, including their life cycle

• Compliance with agreed delivery deadlines

• The level of attention and support provided during the commercial relationship

• Responsiveness to unforeseen situations or adverse conditions

Furthermore, in cases where a supplier is considered unique or their product/service has distinctive characteristics, the evaluation results will receive special attention—even if overall performance has been satisfactory.

Similarly, at Uriarte Safybox we firmly believe it is our responsibility to take concrete action to protect the environment and contribute to sustainable development. That is why we have chosen to implement an Environmental Management System based on ISO 14001.

The primary objective of ISO 14001 is to help us identify, control, and reduce the environmental impacts of our operations and activities. By implementing this system, we commit to complying with applicable environmental laws and regulations, preventing pollution, and continuously improving our environmental performance.

We want our suppliers to be active participants in this important initiative. We firmly believe that working in collaboration with you and other stakeholders in the supply chain is essential to achieving our environmental goals and creating a more sustainable future.

For this reason, we encourage you to join our sustainability initiative and take steps to reduce your own environmental impact. Here are some actions we suggest:

• Waste reduction: Implement practices to reduce, reuse, and recycle waste generated in your production or service processes

• Energy efficiency: Adopt technologies and measures to reduce energy consumption and support the use of renewable sources

• Sustainable material selection: Choose materials and products that are environmentally friendly and have a lower life‑cycle impact

• Sustainable transport: Seek ways to optimize the transportation of your products or services to minimize carbon emissions

We are confident that, by working together, we can make a meaningful difference in our management system and in protecting the environment—and help build a greener, more sustainable world for future generations.

We thank you in advance for your commitment and hope we can count on your support in achieving our shared objectives. If you have any questions or suggestions, please do not hesitate to contact us.

We remain open to dialogue and continuous improvement in this important area.

Sincerely,

Uriarte SAFYBOX, S.A. Team.
