EXPLANATORY NOTE

This registration statement (this “Registration Statement”) is filed by ZK International Group Co., Ltd., an exempted company incorporated under the laws of the British Virgin Islands (the “Registrant”) to register securities issuable pursuant to the ZK International Group Co., Ltd. 2025 Equity Incentive Plan (as amended and restated, “the 2025 Equity Incentive Plan”). The securities registered hereby consist of 650,000 Ordinary Shares of a single class, with no par value per share of the Registrant, which represent the number of Ordinary Shares of a single class that were authorized under the 2025 Equity Incentive Plan. Pursuant to Rule 416(a) under the Securities Act of 1933, as amended (the “Securities Act”), this Registration Statement also covers an indeterminate number of additional shares which may be offered and issued to prevent dilution from share splits, share dividends or similar transactions as provided in the 2025 Equity Incentive Plan. Any Ordinary Shares covered by an award granted under the 2025 Equity Incentive Plan (or portion of an award) that terminates, expires, lapses or repurchased for any reason will be deemed not to have been issued for purposes of determining the maximum aggregate number of Ordinary Shares that may be issued under the 2025 Equity Incentive Plan.

Item 6. Indemnification of Directors and Officers.

Under British Virgin Islands law, each of our directors and officers, in performing his or her functions, is required to act honestly and in good faith with a view to our best interests and exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances. British Virgin Islands law does not limit the extent to which a company’s memorandum and articles of association may provide for indemnification of officers and directors, except to the extent any indemnification provision may be held by the British Virgin Islands courts to be contrary to public policy (for example, such as to provide indemnification against civil fraud or the consequences of committing a crime).

Under our memorandum and articles of association, we may indemnify our directors against all expenses, including legal fees, and against all judgments, fines and amounts paid in settlement and reasonably incurred in connection with civil, criminal, administrative or investigative proceedings to which they are party or are threatened to be made a party by reason of their acting as our directors. To be entitled to indemnification, these persons must have acted honestly and in good faith with a view to the best interests of the company and, in the case of criminal proceedings, they must have had no reasonable cause to believe their conduct was unlawful. The decision of our board of directors as to whether such a person acted honestly and in good faith with a view to the best interests of the company and as to whether the person had no reasonable to cause to believe that his or her conduct was unlawful is, in the absence of fraud, sufficient for the purposes of the indemnification, unless a question of law is involved. The termination of any proceedings by any judgment, order, settlement, conviction or the entry of no plea does not, by itself, create a presumption that a director did not act honestly and in good faith and with a view to our best interests or that the director had reasonable cause to believe that his or her conduct was unlawful. Such limitation of liability does not affect the availability of equitable remedies such as injunctive relief or rescission. These provisions will not limit the liability of directors under United States federal securities laws.

We may indemnify anyone serving at our request as a director of another entity against all expenses, including legal fees, and against all judgments, fines and amounts paid in settlement and reasonably incurred in connection with legal, administrative or investigative proceedings. To be entitled to indemnification, such a person must have acted honestly and in good faith with the view to our best interests and, in the case of criminal proceedings, must have had no reasonable cause to believe that his or her conduct was unlawful. The decision of our board of directors as to whether the person acted honestly and in good faith with a view to our best interests and as to whether the person had no reasonable cause to believe that his or her conduct was unlawful, is in the absence of fraud sufficient for the purposes of indemnification, unless a question of law is involved. The termination of any proceedings by any judgment, order, settlement, conviction or the entry of no plea does not, by itself, create a presumption that the person did not act honestly and in good faith and with a view to our best interests or that the person had reasonable cause to believe that his or her conduct was unlawful.

We may purchase and maintain insurance in relation to any of our directors or officers against any liability asserted against the directors or officers and incurred by the directors or officers in that capacity, whether or not we have or would have had the power to indemnify the directors or officers against the liability as provided in our memorandum and articles of association.

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

Item 7. Exemption from Registration Claimed.

Not applicable.

Item 8. Exhibits.

Reference is hereby made to the Exhibit Index, which is incorporated herein by reference.

Item 9. Undertakings.

A. The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(a) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(b) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement; and

(c) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

provided, however, that paragraphs (1)(a) and (1)(b) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment 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.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

B. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement 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.

C. 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 Commission, 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.
