Serious alert and border rejection notifications on food contact materials (FCM) retrieved from the RASFF database were analyzed for the first time regarding the period 2012–2019. The findings indicate that China was the main transgressor country for both types of notifications. Official controls were responsible for most FCM serious alerts (91.78%), and border rejection (90.82%) notifications. Another novelty proposed herein, is the criterion for “lag phases” (time from sampling to notification dates). Overall percentage distributions of lag phases, for all RASFF Member States, for the intervals of 0–50 days and 51– ≥ 101 days, were 25.09% and 67.87% for serious alert notifications and 65.21% and 29.34% for serious border rejection notifications. Differences in percent shares of lag phase intervals were observed between the top-four notifying countries, indicating a lack of harmonization in timely reporting of serious alert and border rejection notifications for FCM. Migration of primary aromatic amines and of metals were the most frequently notified hazards overall in the period of analysis. A decreasing trend is observed in the two more recent biannual averages of serious alert notifications for primary aromatic amines and metals, while decreasing for metals but increasing for primary aromatic amines in serious border rejection notifications.
