Reference is hereby made to the Registration Statement on Form S-8 being filed by DuPont de Nemours, Inc.

In connection with this opinion, I have assumed the genuineness of all signatures on all documents examined by me and the authenticity of all documents submitted to me as originals and the conformity to the originals of all documents submitted to me as copies.

Based on the foregoing, and subject to the assumptions, limitations and qualifications herein set forth, it is my opinion that:

1.	The Company is validly existing and in good standing under the laws of the State of Delaware; and
2.	The Common Stock has been duly authorized for issuance and, when issued and delivered in accordance with the terms set forth in the applicable plan, will be validly issued, fully paid and nonassessable.

I do not express any opinion with respect to the law of any jurisdiction other than Delaware corporate law (including, to the extent applicable, the Delaware constitution and judicial decisions) and I do not express any opinion as to the effect of any other laws on the opinion herein stated. This opinion is given as of the date hereof. I assume no obligation to update or supplement this opinion to reflect any facts or circumstances which may hereafter occur or come to my attention or any changes in law which may hereafter occur.
