Chociaż przepisy poszczególnych krajów różnią się od siebie, zabraniają one angażowania się w jakąkolwiek formę korupcji lub łapownictwa i wymagają od firm prowadzenia ksiąg, rejestrów i rachunków w odpowiednim zakresie szczegółowości Naruszenia tych przepisów mogą skutkować szkodą dla reputacji firmy Avient, poważnymi karami i pozbawieniem wolności. Czasami osoby nie uważają siebie za urzędników państwowych lub nie są traktowane jako takie przez ich własne rządy, ale mogą one spełniać powyżej sformułowaną definicję urzędnika państwowego. Mogą one również być źródłem wyzwań w obszarze przestrzegania przepisów, dlatego też firma Avient musi podjąć odpowiednie kroki w celu zapobiegania przekupstwu.
