Final grading involves a colour evaluation that divides fox skins into various groups according to colour tones. The initial grading is double checked.

Clarity

Fox skins are graded according to the degree of clarity, or the colour tone of the fur. The skins are separated into four clarity groups.

Nap (Guard hair)

Fox skins are also graded according to the length of the guard hair (nap) and are divided into three groups:
Short Nap
Normal Nap
Long Nap
