The definitions of Grading and Classing of fleece wool

Grading of fleece wool

Grading is defined as seeking to make one only, well prepared and even line of wool for sale by removing those fleeces that differ appreciably from the bulk of the wool.

Application of grading

Grading is a system that is particularly suitable to clips where the fineness and length ranges are not excessive and where the end use of the wool and the particular fineness grade do not warrant splitting it into more than one line. Most reasonably bred and managed Crossbred ewe clips (Romney, Coopworth and Perendale) would, in their entirety, be suited as carpet wools and contain little or no wool that would qualify for a higher price. This would be true also of many crossbred hogget clips. In some cases, Mid Micron Hogget clip can be graded as they do not require splitting as fineness and length range are not excessive.

Classing of fleece wool

Classing is defined as ‘the overall management of clip preparation and separating of fleeces into sale lines in the shed, taking into account such factors as breed type, fineness, length, soundness, style, and colour. To maximise value in the marketplace.

Application of classing

Classing is a system that applies when:

• The clip is large enough to warrant splitting into lines on various technical parameters without the risk of producing unduly small lines.
• The range of fineness or style or length does not allow grading to be a satisfactory system.
• There are wools present which if separated into a line on their own would achieve a significantly better sale price without lowering the value of the balance of the clip.
