The Dutch animal feed sector applies the same quality assurance system as the international foodstuffs industry: pro-active quality assurance based on Hazard Analysis & Critical Control Points (HACCP). The HACCP risk management system complements the existing Good Manufacturing/Managing Practice quality assurance standards (GMP). The GMP+ HACCP quality assurance system (known as GMP+) is being expanded to cover the entire chain, from feed ingredients producer to transport company and livestock farmer. Independent inspectors monitor compliance within the system, and companies that contravene the rules may lose their GMP or GMP+ certificate.

Contitank is both ISO 9001-2000 and GMP+ International (=GMP + HACCP) certified.
