Leather is a durable and flexible material created via the tanning of putrescible animal rawhide and skin, primarily cattlehide. It can be produced through different manufacturing processes, ranging from cottage industry to heavy industry.

The leather and the fur industries are differentiated by the manufacturing importance of the raw materials used to make the wares. In the leather industry, the skin and rawhide are by-products of the meat industry, because the meat has greater commercial value than the rawhide and skin. In the fur industry, the meat is a by-product, because the skins and hides have greater commercial value. Moreover, in taxidermy, the raw materials usually are only the animal’s head and back; hide and skin also are the raw materials for manufacturing animal glue and gelatin.
