The term "mohair" or "cashmere" or any words, coined words, symbols or depictions connoting or implying the presence of such fibers shall not be used in non-required information on the required label or on any secondary or auxiliary label attached to the wool product if the term "mohair" or "cashmere," as the case may be, does not appear in the required fiber content disclosure.
