    PFAS means a class of fluorinated organic chemicals containing at least one fully fluorinated carbon atom. Intentionally added priority chemical or intentionally added means a chemical that serves an intended function in the final product or in the manufacturing of the product or part of the product; chemicals present from recycled materials are not intentionally added. Ecology presumes detection of total fluorine indicates intentional addition of PFAS (above 50 ppm for the later-dated products); a manufacturer may rebut.
