What types of ABP (animal by products) need to be notified using IPAFFS and when do I have to pre-notify the movement on IPAFFS?

There are staged requirements for pre-notification using IPAFFS depending on the category and type of the ABP. The answer is on p73 of the Border Operating Model.

You must submit your notification in IPAFFS at least one working day before the expected time of arrival at the point of entry. You can submit your notification up to 30 days in advance.
