In 2000, Proquinorte implemented a Quality System based on the UNE-EN ISO 9001 standard, requiring strict quality controls in all work processes. All products marketed by our organization are approved and undergo strict quality controls based on compliance with the aforementioned standard. Proquinorte's primary objective is to provide the best possible service to its customers, and Quality Management is undoubtedly the most appropriate way to earn their trust and satisfaction. Proquinorte is Quality Certified in Spain and England, passing strict control audits in both countries. In 2018, we implemented an environmental management system based on the UNE-EN ISO 14001 standard.
