Zaradi pravilne uporabe določb o postopku lahko carinski organi zaradi lažjih kontrol predvidijo, da imetnik dovoljenja vodi ali naroči voditi evidence, v nadaljevanju "evidence predelave pod carinskim nadzorom", iz katerih so razvidne količine uvoznega blaga, dane v postopek, in pridobljeni predelani proizvodi, pa tudi vsi podatki, ki so potrebni za spremljanje operacij in pravilno določitev morebitnih plačljivih uvoznih dajatev.
