Certification of fertilizers is a rigorous process that requires detailed assessments and adherence to strict rules. Zsuzsanna Németh, inorganic fertilizer expert and auditor, explains the steps that manufacturers must follow to comply with the European Union’s Fertilizer Product Regulation (FPR). Certification ensures that fertilizers meet quality and environmental requirements. Zsuzsa explains: “The CE marking is a sign of conformity and trust that allows the marketing and use of fertilizing agents in the European Union.”
The FPR sets out specific criteria for fertilizers, including nutrient composition, contaminant limits and environmental impacts. Manufacturers must demonstrate compliance through rigorous testing and documentation.
Notified Bodies such as CerTrust are responsible for assessing the conformity of fertilizing agents. “Our job is to check that the product meets all regulatory requirements,” says Zsuzsa. This includes reviewing the manufacturing quality management system. The manufacturer’s technical documentation and laboratory tests, depending on the product’s classification category.
The certification process begins with the manufacturer submitting an application for assessment of their product. Zsuzsa details the steps: “We review the technical documentation, perform the necessary tests. If necessary, check the production and product quality during an onsite audit and prepare a conformity assessment report.” The certificate can be issued after any deficiencies have been corrected.
The FPR allows for different certification modules. Zsuzsa describes modules A, B+C and D1, which require different verification. “The choice of conformity assessment module depends on the functional and component category of the product.”
Timelines and challenges
Certification typically takes two to three months, depending on the complexity of the product and the responsiveness of the manufacturer. Zsuzsa notes: “Delays can occur if the documentation is incomplete or if additional supplements are required.”
Non EU manufacturers also need to comply with the FPR rules if they want to sell their products on the European market.
Certification is not a one off process: “Certifications have to be renewed every three to five years, depending on the certification module used,” explains Zsuzsa. If the manufacturing quality management system is also certified, regular audits (annually, but sometimes more often) ensure that manufacturers are always compliant.
If a product does not meet the requirements, it cannot be marketed in the EU. “Non-compliance has significant consequences, but manufacturers can reapply after the deficiencies have been corrected,” says Zsuzsa.
Consumer and environmental protection
The main goal of the certification process is to protect both consumers and the environment. Zsuzsa concludes: “By adhering to strict rules, we ensure that fertilising products support sustainable agricultural practices without compromising environmental and food safety.”
