Portonave has an integrated management system certified by the standards NBR ISO 9001 and NBR ISO 14001 (see more on page 17). Its procedures are audited annually by the firm Bureau Veritas Certification, a certification agency accredited by Inmetro, based on quality and environmental management criteria.
It also regularly conducts specific audits of information systems and of the processes that control access by people, vehicles and cargo, given Portonave’s responsibility for customs control. These procedures also have the function of providing information to government agencies, such as the Federal Revenue Service, the Ministry of Agriculture, Livestock and Supply (MAPA) and the Brazilian Health Surveillance Agency (ANVISA).
Portonave’s controlling shareholders include a publicly traded company (Triunfo Participações e Investimentos), for which reason it is also subjected to audits of its quarterly financial statements by independent auditors. In 2015, the firm responsible for auditing its financial statements was Ernst & Young.
