Tithe Grade

Tithe Grade, also named the Great Harvesting or Terra's Due² refers to the amount of materials an Imperial world must supply to the Administratum. The size of the tithe depends on the type of world it is applied to. A tithe can be any form of material: food, weapons, minerals, people, etc..

It is the duty of Planetary Governor's to ensure the tithe of their world is paid, and any world which fails to pay its tithe meets with vicious reprisal from the Adeptus Terra. However as long as the planetary ruler dutifully pays his worlds tithe, he may rule the planet in almost any way he sees fit.²

Space Marine homeworlds do not normally have tithes, and are given the tithe grade Aptus Non while Agri world tithes generally refer to how much of the planet's food production must be supplied.
