Essential knowledge and skills

Essential knowledge

This knowledge should be acquired through learning to fulfill the role of hide grader.

  • Physico-chemical properties of hides and skins: The quality of hides and skins is defined by organoleptic, microbiological, histological and chemical characteristics (i.e. moisture, structure of the dermis, percentage of fat and collagen). Each type of hide/skin has specific physical and chemical properties that affect the type of tanning operations and the most suitable end use of the leather.
  • Physico-chemical properties of crust leather: The properties, physical and chemical, of intermediate leather products that have already undergone tanning operations. These properties vary depending on the animal of origin and previous manufacturing processes.

Essential skills and competences

These skills are necessary for the role of hide grader.

  • Think analytically: Produce thoughts using logic and reasoning in order to identify the strengths and weaknesses of alternative solutions, conclusions or approaches to problems.
  • Adapt to changing situations: Change approach to situations based on unexpected and sudden changes in people’s needs and mood or in trends; shift strategies, improvise and naturally adapt to those circumstances.
  • Use communication techniques: Apply techniques of communication which allow interlocutors to better understand each other and communicate accurately in the transmission of messages.
  • 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.
