Identify defects on raw hides

Analyse, identify and evaluate the possible defects present on raw hides/skins. Defects may be of natural origin (e.g. damage by parasites), caused by bad practices at the farm, in transport, at the abattoir (e.g. incorrect flaying, pre-slaughter defects, improper conservation) or generated during the manufacturing process. The classification of Hides/skins and their subdivision into “selections” is based on the nature, magnitude and location of defects. The class of selection determines the type of processing, and consequently the type of article.
