Suzano oversees certifications related to forestry and industrial operations, corporate procedures, commercial activities, and international offices. These attest to our commitment to responsible social and environmental conduct throughout various stages of our business. We have specialized teams responsible for guiding different departments to align their practices with the standards set by nationally and internationally recognized certifications.

Our certifications exemplify Suzano's dedication to operational excellence and facilitate the ongoing enhancement of processes and products, thereby benefiting customers, suppliers, employees, society, and the environment. To achieve this, internal and external audits are conducted annually, which may be hybrid (comprising both in-person and remote assessments) or fully in-person, in accordance with the guidelines set forth by the International Accreditation Forum (IAF) and other regulatory standards.

Suzano is internationally acclaimed for its responsible practices. Its internal policy emphasizes the ongoing expansion of its certified forestry base to certify the company's entire operations. The aim is to ensure adherence to the rigorous Forest Stewardship Council® (FSC®) and Programme for the Endorsement of Forest Certification (PEFC) standards.

Furthermore, we are dedicated to certifying all of the company's new industrial operations, including newly acquired ventures or newly established production lines, in accordance with the FSC, PEFC, and SFI® Chain of Custody standards (applicable solely to industrial operations within the United States). This approach ensures that all operational units and products associated with Suzano adhere to the chain of custody, thereby maintaining the traceability of forest products and inputs, and ensuring compliance with international certification standards and relevant legislation. Such measures help mitigate social and environmental risks and impacts through the responsible management of forest plantations.

Another important aspect of our commitment to sustainability is the audits conducted on contractors who provide services to Suzano, such as product processing, storage, distribution, and labeling. These audits aim to ensure strict compliance with forest certification standards and legislation throughout the production chain, thereby guaranteeing the integrity and transparency of our processes.

Through annual critical analyses, the teams responsible for certifications identify opportunities for improvement and make decisions in accordance with Suzano's short-term, medium-term, and long-term strategic objectives, emphasizing the ongoing enhancement of operational processes.

Forest Stewardship

Forest Stewardship certifications aim to ensure the proper utilization of natural resources and foster engaged and committed human relations. Responsible Forest Stewardship originates from a robust socio-environmental governance framework that adopts leading sustainability practices and standards, with the objective of safeguarding, restoring, and promoting the sustainable use of ecosystems. Additionally, it seeks to generate value for all stakeholders involved, in strict accordance with Suzano's strategic objectives and long-term vision.

The company reaffirms its commitment to adhering to the principles and criteria of the FSC® and PEFC, demonstrating exemplary conduct through the development of forest products that respect the environmental, social, and economic considerations of each region in which it operates.

The Forest Stewardship certification standards delineate the criteria for the company to develop and execute a monitoring plan, encompassing indicators and targets to be met concerning pertinent environmental, social, and economic facets. These criteria are subject to verification and assessment during annual audits, with corresponding reports issued. The status of management certifications, including valid, suspended, terminated, or blocked, is publicly disclosed on the FSC® and PEFC websites.

Rooted in ethical principles and transparency, we comprehensively oversee the aspects and potential impacts of our Forest Stewardship activities. We implement effective measures to eliminate or mitigate these impacts caused by our forestry operations. Furthermore, we have developed metrics for mapping these possible impacts and methodologies for monitoring and control, which support the continuous enhancement of our processes.

Forest certification promotes enhancements in biodiversity preservation and the sustenance of ecosystem services. It contributes to carbon sequestration, road upkeep, soil erosion prevention, and the enhancement of health and safety conditions in the workplace. Additionally, it fosters involvement and engagement with local communities and aids in managing legal and administrative matters concerning the origin of timber and its derived products.

Suzano establishes communication mechanisms with the most diverse segments of society (stakeholders), ensuring they are informed about its activities. Among these mechanisms are dedicated platforms for receiving comments and complaints from stakeholders. Communication with stakeholders affected by forestry operations is conducted through the Operational Dialogue instrument, as well as records of occurrences, resolutions, and mitigating measures implemented. Additionally, the Complaints Channel offers an anonymous platform for submitting complaints from both internal and external audiences. Complementing these channels, the company operates Suzano Responde, a contact service via telephone and email that facilitates the registration of complaints and inquiries from interested parties.

The forestry certifications, in their auditing processes, oversee the scope and effectiveness of the company's communication channels intended for both internal and external stakeholders, including those in rural areas and industries. These processes ensure that communication channels are accessible and available to interested parties, and that complaints and suggestions are received, evaluated, and addressed in accordance with the company's internal policies, forestry certification standards, and applicable legislation.

Chain of custody

Our marketed products, including pulp, Eucafluff, paper, and tissue/consumer goods, are certified under FSC® and PEFC chain of custody standards, ensuring the responsible sourcing of 100% of the wood and demonstrating transparency and good manufacturing practices throughout the production process. Additionally, our paper products manufactured in the United States are certified under SFI® standards.

The chain-of-custody certification affirms the traceability of forest-origin products, extending from raw material production to the final product received by the consumer, whilst also encompassing considerations regarding working conditions, health, and safety standards.

Suzano is dedicated to the implementation and maintenance of chain of custody requirements in accordance with internationally recognized norms and standards. To achieve this, it has established a traceability program staffed by trained professionals, equipped with computerized systems, and subject to annual inspections conducted by both internal and external third-party audits.

The commitment to standards, laws, and certifications is delineated in the Wood Procurement Policy, which establishes criteria for the acquisition of land and timber in accordance with: 

• Brazilian Forestry Code;
• Criteria of the FSC® Association Policy;
• Forest Stewardship and chain of custody standards of FSC®, PEFC, and SFI®;
• FSC® controlled wood, PEFC controlled sources, and SFI® Fiber Sourcing Program;
• European Timber Regulation (EUTR);
• United Kingdom Timber Regulation (UKTR);
• Lacey Act (USA);
• Australian Illegal Logging Prohibition Act;
• Fundamental Principles of the International Labor Organization (ILO).

Industrial operations

The industrial certifications demonstrate adherence to best practices in process management across the factories, ensuring customer satisfaction, ongoing operational improvement, environmental conservation, and employees' occupational health and safety in a balanced manner.  

Suzano maintains comprehensive certifications (ABNT NBR ISO 9001:2015 | ISO 14001:2015 | ISO 45001:2018) at its manufacturing facilities, port terminals, corporate offices, and international branches. Notably, the company has committed to the NBR 15755 Reciclato certification and to the protocols established by SMETA and EcoVadis.  
 

SMETA

The SMETA audit (Sedex Members Ethical Trade Audit) is a socially-focused assessment developed by the international organization Sedex to evaluate ethical and responsible practices within procurement supply chains. Its purpose is to ensure that companies and suppliers conduct their operations ethically, sustainably, and in alignment with international social responsibility standards.  

At Suzano, Smeta protocol audits are conducted upon client request for on-site evaluations and remain valid for three years.

Suzano S.A. holds ISO certification for its industrial facilities and port terminals, as detailed in the tables below

ISO certifications for industrial units

In 2025, Suzano received recertification across all three standards. Given that the company's certification is multisite, meaning a single certificate covers all units. Pursuant to the choice of the certifying authority (Bureau Veritas Certification), the units audited for recertification include: Suzano, Três Lagoas, Jacareí, Limeira, along with the Central Office and International Offices (Stenfar Office - Argentina, Europe Office, United States Office).  

Following this recertification year, Suzano will be granted two years to uphold the certificate, during which the units not assessed in 2025 will undergo auditing, thereby completing a three-year cycle in which all certified units will have been audited.
Certification Cycle:

• 1st year: recertification audit involving the units defined between our certifier, Bureau Veritas, and Suzano.
• 2nd and 3rd years: maintenance audits are conducted at the units that did not participate in the Recertification Process.

In this manner, all units undergo an audit at least once during this three-year cycle. It is crucial to emphasize that, following the recertification audit in the first year, the certificate is effective and will remain valid for 3 years. A new cycle will commence only in 2028 with a subsequent re-certification process.

The Ribas do Rio Pardo (MS) unit was incorporated into the external audit cycle in 2025. Consequently, upon completion of the audit, it will be integrated into the multisite certificate issued in January 2026, at the conclusion of the ongoing recertification process scheduled between October and December 2025.
Port terminals:  
 

Port terminals have a distinct certification process compared to industrial operations, despite the management structure remaining consistent, following a 3-year cycle: the initial year is dedicated to recertification, and the subsequent two years are allocated to maintenance. The most recent recertification took place in 2023, with the first maintenance scheduled for 2024 and the second in 2025. In 2026, the terminals will initiate a new recertification process cycle.

Certification cycle:

• 1st year:  recertification audit in which the two terminals are audited on all their processes;
• 2nd and 3rd years: audits at both terminals, but on specific processes defined by the certifier's auditor.
