Grades to leather are given by either the manufacturer OR the store that is selling it. If the manufacturer has applied a grading system, they are using the numbers/letters to tell you either a) what type of leather was used or b) how the leather was finished or a combination of the two.
Coated leather is defined as a product that has a finish thickness of less than 30 percent but greater than 0.15 mm.
