CHEMICAL TREATMENT OF HIDES, SKINS OR LEATHER, e.g. TANNING, IMPREGNATING, FINISHING; APPARATUS THEREFOR; COMPOSITIONS FOR TANNING (bleaching of leather or furs D06L; dyeing of leather or furs D06P)

Introduced: September 1968

Description

C14C covers chemical, enzymatic, and microbiological processing of animal skins, hides, and leather, including tanning, impregnation, and finishing operations. This subclass encompasses tanning agents and compositions (mineral, vegetable, synthetic), enzymes and microorganisms used in leather processing, and apparatus designed for treatment applications. It addresses both traditional and modern leather production methods, including hide preservation, coloration, water-resistance treatment, and surface finishing. Related mechanical or preparatory treatments of raw hides are classified separately under C14B.
