Tea is graded on the basis of the condition of its leaf (leaf grades) after the last stage of production, the sorting stage. There are 4 basic groups in orthodox production: leaf, broken, fannings and dust. These categories have nothing to do with quality, but only indicate the different leaf sizes and associated strengths.
