According to internationally accepted grading methods,
grading depends upon the the number of quarters in which
defects can be found within the central "diamond"
area (see below).
A defect can be a holes, scratch, loose scab, a healed
wound or bacterial damage but must be less than 40 mm
x 40 mm in size.
Grade 1 - defects permitted in 1 quarter only
Grade 2 - defects in 2 quarters only
Grade 3 - defects in 3 quarters only
Grade 4 - defects in 4 quarters
Super Premium - virtually a flawless hide with no visible
defects in any of the four quarters or surrounding skin
Premium - no visible defects in any of the four quarters
but may have a few defects in the surrounding skin.
