We believe that integrity, sustainability, and respect for people and the environment must be present throughout the entire value chain. Therefore, our suppliers are expected to adopt conduct that is consistent with the organization’s values, in compliance with the following principles:

• Legal and ethical compliance

          Compliance with applicable legislation, rejection of unlawful practices, and respect for the confidentiality of information.

• Environmental and social responsibility

          Promotion of fair working conditions, responsible use of resources, and protection of the environment.

• Health, safety and quality

          Ensuring safe workplaces, appropriate training, and the delivery of products and services that meet quality and conformity requirements.

• Shared responsibility

        Application of these principles to sub-suppliers as well, including cooperation in audits and continuous improvement initiatives.

These principles are detailed in our Supplier Code of Conduct, adherence to which is formalized through the signing of a Declaration of Commitment.

All suppliers and subcontractors must:

• Inform the local responsible person of the start and end of the service provision;
• Use appropriate personal protective equipment (PPE) suitable for the service being performed;
• Ensure continuous training of the technicians involved, duly recorded and made available upon request;
• Comply with circulation rules within the facilities, ensuring that access routes and emergency equipment (fire extinguishers, hose reels, etc.) are not obstructed;
• Respect the prohibition of smoking inside the facilities;
• Report all work-related incidents/accidents occurring during the provision of the service;
• Promote the reduction of waste generation and ensure its proper segregation and disposal;
• Adopt measures aimed at minimizing atmospheric pollutant emissions, such as dust;
• Provide documentation proving compliance with environmental legislation whenever required;
• Immediately report any spills to the local responsible person;
• Ensure that the vehicles used are in good condition, avoiding excessive noise and pollutant emissions;
• Use resources such as water and energy rationally and efficiently;
• Ensure that the packaging of chemical products supplied or used is properly identified and labeled in accordance with applicable legislation, and remains closed after use.

Suppliers are evaluated based on the following criteria:

• Delivery Time – Effectiveness in meeting delivery deadlines;
• Quantity – Effectiveness in handling complaints and level of technical support;
• Quality – Conformity of the supply and reliability of the product/service;
• Price – Price changes and financial conditions;
• Other – Number of complaints due to poor supplier performance, customer service, and adequacy of supporting documentation.

Each criterion is assessed on a scale from 1 to 3.

If the overall evaluation is above 2, the supplier is classified as “Preferred”, and the supplier relationship is maintained.

When the evaluation score is between 1.5 and 2, the supplier is classified as “Adequate”. In this case, the supplier is maintained, although improvement actions may be recommended.

Finally, if the evaluation result is equal to or below 1.5, the supplier is classified as “To Be Replaced”, leading to the exclusion or replacement of the supplier.
