EPA: Federal Register: Sulfuryl Fluoride; Proposed Pesticide Temporary Tolerances:

"This document proposes to establish temporary tolerances for
sulfuryl fluoride and inorganic fluoride residues resulting from
application of sulfuryl fluoride in or on walnuts and raisins under the
Federal Food, Drug, and Cosmetic Act"

3) Temporary tolerances are established for residues of fluoride
resulting from the post-harvest treatment with sulfuryl fluoride. The
tolerances are measured and expressed as ppm of fluoride. Total
residues of fluoride in or on raisins from use of cryolite on grapes
(addressed in paragraph (a)(1) of this section) or sulfuryl fluoride on
raisins shall not exceed the tolerance list in the following table.
