Explanatory Note

              This Amendment No. 6 to the Registration Statement on Form S-1 (Registration No. 333-217753) (the "Registration Statement") is being filed for the sole purpose of filing Exhibit 5.1 to the Registration Statement. No changes or additions are being made hereby to the Prospectus constituting Part I of the Registration Statement (not included herein) or to Items 13, 14, 15 or 17 of Part II of the Registration Statement.

Part II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 13.    Other Expenses of Issuance and Distribution

              The following table sets forth an itemized statement of the amounts of all expenses (excluding underwriting discounts and commissions) payable by us in connection with the registration of the ordinary shares offered hereby. With the exception of the SEC registration fee, the Financial Industry Regulatory Authority ("FINRA") filing fee, and the NYSE listing fee, the amounts set forth below are estimates.

Item 14.    Indemnification of Directors and Officers

              We plan to enter into indemnification agreements with our directors and executive officers to indemnify them to the maximum extent allowed under applicable law. These agreements indemnify these individuals against certain costs, charges, losses, liabilities, damages and expenses incurred by such director or officer in the execution or discharge of his or her duties. These agreements do not indemnify our directors against any liability attaching to such individuals in connection with any negligence, default, breach of duty or breach of trust in relation to the company of which he or she is a director, which would be rendered void under the Companies Act 2006. The U.K. specific restrictions apply to directors but not officers.

              The proposed form of Underwriting Agreement filed as Exhibit 1.1 to this registration statement provides for indemnification of our directors and officers by the underwriters against certain liabilities arising under the Securities Act or otherwise in connection with this offering.

              Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

              We intend to maintain liability insurance policies that indemnify our directors and officers against various liabilities, including certain liabilities under arising under the Securities Act and the Exchange Act, that may be incurred by them in their capacity as such.

Item 15.    Recent Sales of Unregistered Securities

              Upon our formation, we issued 50,000 of our ordinary shares, par value £1 per share (the "Subscriber Shares"), to Huntsman International (Netherlands) B.V., an indirect wholly-owned subsidiary of Huntsman. On June 30, 2017, (a) Huntsman International (Netherlands) B.V. transferred the Subscriber Shares to Huntsman International, and (b) we issued 50,000 redeemable shares, par value £1 per share, and one ordinary share, par value $1 per share, to Huntsman International, all of which (including the Subscriber Shares) will be repurchased by us prior to the consummation of the offering. Prior to the consummation of the offering, we expect to issue 106,271,712 ordinary shares, par value $0.001 per share, to Huntsman through its wholly-owned subsidiaries Huntsman International and HHN. Immediately prior to the completion of this offering, we expect Huntsman International and HHN will be the sole shareholders of Venator. Immediately following the completion of this offering, we expect Huntsman to hold its Venator ordinary shares through one or more subsidiaries, including HHN. Each issuance of shares made prior to the issuance of shares in this offering was, or will be, made pursuant to the exemption from registration in Section 4(a)(2) of the Securities Act because the offer and issuance of the ordinary shares did not, or will not, involve a public offering, and we have not otherwise sold any securities, registered or otherwise, within the past three years.

Item 16.    Exhibits and Financial Statement Schedules

              (a)   Exhibits. See the Exhibit Index immediately following the signature page hereto, which is incorporated by reference as if fully set forth herein.

              (b)   Financial Statement Schedules. Financial statement schedules are omitted because the required information is not applicable, not required or included in the financial statements or the notes thereto included in the prospectus that forms a part of this registration statement.

Item 17.    Undertakings

              The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

              Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

              The undersigned registrant hereby undertakes that:

              (1)   For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

              (2)   For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-2
