5. 13.112 Preparation of animal fibers for textile use

What 13.112 includes

• The term "wool" is used exclusively for the hair provided by sheep or rams, reserving the generic term "hair" for other mammals. Raw wool from field shearing (class 01.44), as well as that from slaughterhouses (class 10.10), contains a large amount of lanolin and debris. Hairs, on the other hand, contain few impurities. Natural silk comes from the mucus or secretion with which the larvae of certain moths, known as silkworms, spin their cocoons. This animal fiber differs from vegetable silk, whose production is classified in subclass 13.111, and which is obtained from plant-based raw materials, more precisely from fibers derived from ramie. It also differs from artificial silk or viscose rayon, which is obtained from cellulose through chemical processes (subclass 20.300).
• The processes for preparing wool, hair, and natural silk.
• The bleaching, dyeing, and similar processes of animal fibers when carried out at the production facilities where they are obtained.
• The arrangement of wool into slivers and tops.
• The carding and combing processes of wool, hair, and natural silk when integrated into the preparation process.
• The generation of byproducts and waste from the aforementioned processes.

What 13.112 excludes

• The raising of animals that provide wool and hair (class 01.442).
• The raising of fur-bearing animals (subclass 01.493).
• The raising of silkworms for the production of natural silk (subclass 01.499).
• The obtaining of hair as a byproduct of the slaughter of small or large game (class 10.109).
• The obtaining of wool and hair as byproducts of slaughter and/or processing in abattoirs and meatpacking plants (subclass 10.104) or of the dehairing of hides (subclass 15.110).
• The processes of preparing vegetable silk (subclass 13.111).
• The activities of wool and hair laundering facilities that are integrated into the spinning (subclass 13.113) or weaving (subclass 13.120) process.
• Bleaching, dyeing, and similar processes for animal fibers carried out in production units separate from the fiber production (subclass 13.130).
• Processes for the preparation of artificial silk (subclass 20.300).
• The production of human hair (hairdressing salons) (subclass 96.020).
