# 300.17 Use of the term “all” or “100%.”
Where the fabric or product to which the stamp, tag, label, or mark of identification applies is composed wholly of one kind of fiber, either the word *all* or the term *100%* may be used with the correct fiber name; as for example “100% Wool,” “All Wool,” “100% Recycled Wool,” “All Recycled Wool.” If any such product is composed wholly of one fiber with the exception of fiber ornamentation not exceeding 5%, such term “all” or “100%” as qualifying the name of the fiber may be used, provided it is immediately followed by the phrase “exclusive of ornamentation,” or by a phrase of like meaning; such as, for example:
All Wool—Exclusive of Ornamentation
or
100% Wool—Exclusive of Ornamentation.
