The Stazione Sperimentale per la Seta (SSS) (Silk Experimental Station) is a special Agency of the Chamber of Commerce in Milan. It is an Institute for applied research, established in Milan in 1923, and operating on a national scale with the specific aim of promoting the technical and technological progress in the silk and derived products industry. In 1999 SSS was transformed into a public economic institution with important legal, operational and administrative modifications which, however, have left its mission and functions unchanged.
