The generic description for leather refers to its fibrous structure, more or less intact, chromed in order to be resistant to rottenness. The hair of the wool might or might have not been removed. The leather for the footwear could also been obtained from animal leather, split into layers before or after being chromed.
However if the leather was mechanically or chemically divided into fibrous particles, has small pieces of dust, with or without using any bonding and transformed into foils or other shapes, it should not be considered as leather.
If the leather is covered with any kind of protective layer or lacquered, these layers should not be thicker than 0.15 mm.
The layer applied should not be more than third percent of leather’s total thickness, but to overcome 0,15 mm.
The term describes all products introduced and described as per Government Decision 527/2007 regarding the naming, fibrous composition and labeling.
