It applies to fresh, raw-dried, wet-salted, dry-salted or pickled sheep skins. 2 Classification and designation 2.1 General Raw sheep skins (wool-on) are classified as follows: a)lamb skins; b)sheep skins. These skins are further divided into following sub-categories: 2.2 Lamb skins 2.2.1 Astrakhan skins New-born-lamb skins, characterized by the tight curls of the fleece, obtained from lambs of the karakul breed slaughtered before the fifth day of life in order to preserve the curls which would break up rapidly after few more days of life. NOTE This type of skin, from a healthy-born animal, should not be confused with a Breitschwanz skin (see 2.2.2) 2.2.2 Breitschwanz skins Obtained from the foetus of an animal of this breed when the ewe is killed for meat 2 to 3 weeks before the birth is due (the curls of the fleece are not fully developed and are in rows, forming patterns of alternate curly areas and smooth, glossy areas of straight wool). 2.2.3 Lessac skins Skins from a four-month foetus, with completely smooth, straight wool several millimetres long.
