In determining the value of cotton samples are drawn from random bale and evaluated according to staple, grade, and character. Staple refers to fibre length. Fibre length can be classified in to three grades i.e. 1) Short staple  2) Medium staple 3) Long and Extra long staple.

Grade refers to color, brightness, and amount of foreign matter.  Color groupings indicate the degree of whiteness. Character refers to the diameter, strength, body, maturity (that is, ratio of mature to immature fibres), uniformity, and smoothness of the fibres.
