I would suggest calling Sigma and asking to speak with a safety specialist.  I am puzzled why the Sigma SDS does not carry the corrosive pictogram and does not warn of corrosivity (as the Pub Chem site does) but in Section 11 the Sigma Aldrich SDS states 'Material is extremely destructive to tissue of the mucous membranes and upper respiratory tract, eyes, and skin., spasm, inflammation and edema of the larynx, spasm, inflammation and edema of the bronchi, pneumonitis, pulmonary edema, burning sensation,"

To me, this does not compute....

if you get someone who is obviously not familiar with this chemical, push to speak with their industrial hygienist...

let us know how this works out--

Regardless of the date, I need to understand the reasoning behind any reclassification in order to assess correctly. Older information is still pertinent and quite honestly more helpful sometimes. I am not finding a good paper trail on this chemical.

What are the publishing dates of each?  One may have new information

Has anyone worked with or know why the SDS from Sigma is drastically different than PubChem for
Pentadecafluorotoctanoyl chloride?  Is this chemical a super acid like some fluoro compounds or is Sigma more correct?
