Suppliers and Customer Relations
Supply chains are one of the most strategic and intricate parts of a large-scale enterprise such as ours. Our relationship with suppliers and customers across the value chain — from our mine operations to the railways transporting our commodities — plays a vital role in the success of our business by ensuring timely delivery of high-quality materials and services while managing health, safety, and human rights risks. Supplier and customers relationships also provide opportunities to enhance value creation for society, especially in the regions where we operate.
In addition to working closely with suppliers to promote responsible practices across our value chain, we also engage with customers to co-create solutions that contribute to a low-carbon economy and generate shared value.

Our approach
In 2024, we signed contracts with around 5,000 suppliers, who play a crucial role in building a more sustainable value chain. These companies operate in various sectors, such as oils and fuels, construction, equipment, maintenance, consulting, food, parts and repairs, among others. Our relationship with suppliers goes beyond the provision of services. We seek partnerships that share our values and are committed to responsible practices aligned with ESG principles. By integrating sustainability criteria into our hiring and management processes, we promote a more ethical, efficient, and resilient operation throughout the supply chain.
Vale promotes human rights compliance at every stage of our relationship with suppliers, from initial selection and onboarding to contract management, supplier development, and training, in line with the United Nations Guiding Principles on Business and Human Rights. Environmental, health, and safety considerations are also addressed in our engagement with suppliers, and we have standards and processes in place for risk monitoring, mitigation, and elimination. These are integrated into our enterprise management system, called the Vale Production System (VPS).

Policies and Documents
Responsible Sourcing
Since 2022, we have a clear commitment to sustainability in our supply chain. Through our Responsible Purchasing Program, we aim to integrate environmental, social, and economic criteria into purchasing decisions, encouraging more ethical and conscious practices among our suppliers.
In 2024 the program has gained even more strength: strategic decisions are now being evaluated by our Board of Directors. This change reinforces leadership involvement and helps us identify and mitigate risks throughout the value chain, promoting an increasingly positive impact.
The first step to strengthen our sustainable performance in the supply chain was the creation of the ESG Criticality Matrix, developed based on the segmentation of our supplier base in Brazil. This matrix considers the environmental, social, and governance (ESG) risks associated with each purchasing category, in line with the guidelines of ISO 20400 – Sustainable Procurement. With it, we were able to classify suppliers according to their potential impacts and levels of exposure to these risks. In 2024, we revised the ESG Criticality Matrix for Vale's new category tree and expanded its application to all regions where we operate, reinforcing our global commitment to responsible practices. Still this year, we updated the purchasing category strategy tool and initiated a new segmentation of supplier’s process, now considering Vale's business strategy, which allows a more robust risk classification, combining ESG criteria with the supplier’s business relevance.

The ESG risk analysis encompasses a wide range of topics, such as greenhouse gas emissions, biodiversity, waste management and water resources, integrity, child labor, and labor analogous to slavery, among others. This approach allows us to make more conscious decisions aligned with our values and commitments to sustainable development. In 2024, all suppliers with active contracts underwent a socio-environmental due diligence process as part of our registration. Of these, 1563 were classified as high or very high risk in our ESG Criticality Matrix and represent more than 50% of Vale's total spend in Brazil.
In addition, about 1,541 non-Tier 1 suppliers were evaluated based on Integrity criteria, focusing on the prevention of risks related to corruption.
Among the suppliers evaluated with potential negative impact, 532 were prioritized for additional analyses, including financial, health and safety, human rights, as well as labor and social security issues, of which 90% received action plans for alignment with our practices and standards. The due diligence is conducted by an independent company, using a methodology widely recognized in the market, which ensures technical rigor and alignment with international best practices.
As part of our commitment to the sustainable development of the supply chain, we provided ESG training for 925 suppliers who represent 59% of those classified as critical in the ESG Matrix Brazil. The actions were carried out by the departments responsible for Human Rights, Climate Change, and the Partilhar Program, focusing on raising awareness and strengthening capacities.
Internally, we also invest in training our internal stakeholders: in 2024, approximately 270 buyers were trained on the Responsible Purchasing Program, reinforcing the strategic role they play in the evolution and effectiveness of the process.

Mobilized contractors
In 2024, of Vale’s 109,000 contracted workers, around 100,000 were engaged in the company’s operations in Brazil, performing a wide range of roles — from mining operations to administrative, transportation, and technology support services.
These workers play a crucial role in our success, and we are committed to ensuring their safety, well-being, and benefits are equivalent to those of our own employees.
In Labour Risk Management (GRT) is responsible for monitoring labor relations and the health and safety of these workers. Monthly checks include reviews of social security payments for all workers. Contractors are also entitled to health insurance.
During the course of a contract, we perform due diligence assessments on aspects that include human rights and health and safety in facilities such as accommodations, dorms, changing rooms, cafeterias, transportation, etc., as well as mandatory documentation and training on aspects such as sustainability, human rights, and diversity.
Risk and impact assessment
A responsible business model requires close oversight throughout the supplier journey, from onboarding to the end of the contract and demobilization. Before entering a business relationship with Vale, all our suppliers undergo due diligence based on publicly available information, consistent with their scope of supply. This due diligence is conducted as part of Vale's Ethics & Compliance Program and covers information related to health and safety, the environment, human rights, and supplier integrity. In Brazil, we also monitor the federal slave labor dirty list and legal environmental requirements, and conduct on-site audits in specific cases.
During the hiring process, suppliers commit themselves, through the Supplier Code of Conduct, to dignified working conditions, combating child labor and sexual exploitation, and respecting the freedom of association and collective bargaining.
Still at the signing of the contract, to reinforce our commitment to responsible purchasing practices, our partners receive the SSMA Guide for suppliers and are engaged through anti-corruption clauses, health, and safety measures, due to the critical nature of the category regarding the management of greenhouse gas emissions, biodiversity, among other issues. The commitments made are periodically reassessed throughout the entire lifecycle of the contract.
This way, Vale ensures the alignment of its purchasing practices with the Supplier Code of Conduct and compliance with ESG requirements, contributing to the prevention of potential risks.
Supplier performance is evaluated throughout the entire contract, and we periodically assess suppliers on social, environmental, humanitarian, performance, and governmental relationship aspects.
To detect, prevent and mitigate risks and resulting impacts, training is carried out, self-diagnosis questionnaires and documentary and field inspections are carried out (including accommodation inspections). When necessary, the supplier is asked to draw up an action plan to address identified weaknesses.
Both risk classification and human rights inspections are carried out by an independent 3rd party assessment, which also verifies and consolidates all training data and completed questionnaires, and also monitors suppliers' action plans. The external consultancy uses standards and methodologies of a recognized industry to carry out verification and monitoring, such as Regulatory Standard No. 4 (NR-4), the Global Estimates of Modern Slavery report, data from the Labor Inspection Secretariat, the Atlas of Children's Rights and Business (Workplace Index), Business for Social Responsibility, Countries Listed as Conflict-Affected and High-Risk Areas, etc.
