**EXPLANATORY NOTE**

This Amendment No. 10 to the Registration Statement on Form F-1 (File No. 333-252127) of CDT Environmental Technology Investment Holdings Limited is being filed solely for the purpose of filing updated Exhibits 5.1, 5.2 and 23.1. Accordingly, this Amendment No. 10 consists of only the facing page, this explanatory note and Part II of the Registration Statement. The Prospectus, constituting Part I of the Registration Statement, is unchanged and has therefore been omitted.

**PART II<br> INFORMATION NOT REQUIRED IN PROSPECTUS**

**Item 6. Indemnification of Directors and Officers.**

Our post-offering memorandum and articles of association, which will become effective immediately upon completion of this offering, empower us to indemnify our directors and officers against certain liabilities they incur by reason of their being a director or officer of our company.

We have entered into indemnification agreements with each of our directors and executive officers in connection with this offering. Under these agreements, we have agreed to indemnify our directors and executive officers against certain liabilities and expenses incurred by such persons in connection with claims made by reason of their being a director or officer of our company.

The underwriting agreement in connection with this offering also provides for indemnification of us and our officers, directors or persons controlling us for certain liabilities.

We intend to obtain directors' and officer's liability insurance coverage that will cover certain liabilities of directors and officers of our company arising out of claims based on acts or omissions in their capacities as directors or officers.

**Item 7. Recent Sales of Unregistered Securities.**

Set forth below is information regarding ordinary shares issued by us during the last three years. None of the below described transactions involved any underwriters, underwriting discounts or commissions, or any public offering.

In connection with our incorporation, in November 2016, we issued an aggregate of 1,000 (pre-split) ordinary shares to certain investors for aggregate consideration of $1.29 (HK$10).

In June 2018, we issued an aggregate of 809,000 (pre-split) ordinary shares to certain investors for aggregate consideration of HK $8,090 ($1,042.80).

In March 2019, we issued an aggregate of 90,000 (pre-split) ordinary shares to certain investors for aggregate consideration of approximately $7.5 million.

In October 2019, our shareholders resolved to create an additional 50,000,000 of authorized ordinary shares with a par value of $0.001, or the Increase in Share Capital. Following the Increase in Share Capital, we issued 23,000,000 ordinary shares with a par value of $0.001, or the USD Shares Issued, to our existing shareholders as fully paid shares at par value. Following the USD Shares Issued, we repurchased and cancelled 900,000 of the then outstanding ordinary shares with a par value of HK$0.01 then issued and outstanding from our existing shareholders and cancelled 38,000,000 of the authorized ordinary shares with a par value of HK$0.01.

We considered the above transactions to be a 25.56-for-1 share split of our ordinary shares and deemed the cancellation of 900,000 original ordinary shares with par value of HK$0.01 and the new issuance of 23,000,000 ordinary shares with par value of $0.001 to our existing shareholders to be part of our recapitalization prior to completion of this offering. We believe it is appropriate to reflect the above transactions on a retroactive basis similar to a stock split or dividend pursuant to FASB ASC 260. All share and per share amounts used herein and in the consolidated financial statements included elsewhere have been retroactively restated to reflect the share split, unless otherwise indicated.

In December 2020, our shareholders resolved to divide 50,000,000 of our authorized ordinary shares with a par value of $0.001, or the Decrease in Share Capital, into 20,000,000 of our authorized ordinary shares with a par value of $0.0025. Following the Decrease in Share Capital, our then existing 23,000,000 ordinary shares with a par value of $0.001 were divided into a total of 9,200,000 ordinary shares with a par value of $0.0025. We considered the above transactions to be a 1-for-2.5 reverse share split of our ordinary shares. We believe it is appropriate to reflect the above transactions on a retroactive basis similar to a stock split or dividend pursuant to FASB ASC 260. All share and per share amounts used herein and in the consolidated financial statements have been retroactively adjusted to reflect the share split, unless otherwise indicated.

We believe that the offers, sales and issuances of the securities described in the preceding paragraphs were exempt from registration either (a) under Section 4(a)(2) of the Securities Act and the rules and regulations promulgated thereunder, in that the transactions were between an issuer and sophisticated investors or members of its senior executive management and did not involve any public offering within the meaning of Section 4(a)(2), (b) under Regulation S promulgated under the Securities Act in that offers, sales and issuances were not made to persons in the United States and no directed selling efforts were made in the United States, or (c) under Rule 701 promulgated under the Securities Act in that the transactions were underwritten compensatory benefit plans or written compensatory contracts.

We have also agreed to issue ordinary shares for a total value of $10,000 to Harry D. Schulman, an independent director, after the consummation of this offering in accordance with the terms of his director agreement. We believe that the offer, sale and issuance of such securities are exempt from registration as described above.

**Item 8. Exhibits and Financial Statement Schedules**

**(a)** **Exhibits**

See the Exhibit Index attached to this registration statement, which is incorporated by reference herein.

**(b)** **Financial Statement Schedules**

**Item 9. Undertakings.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The undersigned registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) That, for the purpose of determining any liability under the Securities Act of 1933, 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Act need not be furnished, provided that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (a)(4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Act if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Form F-3.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) If the registrant is relying on Rule 430B:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ii) If the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreements, certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 provisions described in Item 6 hereof, or otherwise, the registrant has been advised that in the opinion of the U.S. Securities and Exchange 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The undersigned registrant hereby undertakes that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

The following opinions are given only as to, and based on, circumstances and matters of fact existing and known to us on the date of this opinion letter. These opinions only relate to the laws of the Cayman Islands which are in force on the date of this opinion letter. In giving these opinions we have relied (without further verification) upon the completeness and accuracy of the Director's Certificate and the Certificate of Good Standing. We have also relied upon the following assumptions, which we have not independently verified:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.1 Copies of documents, conformed copies or drafts of documents provided to us are true and complete copies of, or in the final forms of, the originals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.2 The genuineness of all signatures and seals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3 There is nothing under any law (other than the law of the Cayman Islands), and there is nothing contained in the minute book or corporate records of the Company (which we have not inspected), which would or might affect the opinions set out below.

---

| | |
|:---|:---|
| **3** | **Opinion** |

---

Based upon the foregoing and subject to the qualifications set out below and having regard to such legal considerations as we deem relevant, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1 The Company has been duly incorporated as an exempted company with limited liability and is validly existing and in good standing under the laws of the Cayman Islands.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.2 The authorised share capital of the Company is US$50,000 divided into 20,000,000 ordinary shares of a par value of US$0.0025 each.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.3 The issue and allotment of the Shares pursuant to the Registration Statement have been duly authorised and when allotted, issued and paid for as contemplated in the Underwriting Agreement and Registration Statement, the Shares will be legally issued and allotted, fully paid and non-assessable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4 The statements under the caption "Cayman Islands Taxation" in the prospectus forming part of the Registration Statement, to the extent that they constitute statements of Cayman Islands law, are accurate in all material respects and that such statements constitute our opinion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.1 In this opinion the phrase "non-assessable" means, with respect to the Shares, that a shareholder shall not, solely by virtue of its status as a shareholder, be liable for additional assessments or calls on the Shares by the Company or its creditors (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.2 Except as specifically stated herein, we make no comment with respect to any representations and warranties which may be made by or with respect to the Company in any of the documents or instruments cited in this opinion or otherwise with respect to the commercial terms of the transactions which are the subject of this opinion.

## Exhibit 5.2

**Exhibit 5.2**

March 29, 2023

CDT Environmental Technology Investment Holdings Limited

C1, 4th Floor, Building 1, Financial Base, No. 8 Kefa Road

Nanshan District, Shenzhen, China 518057

Ladies and Gentlemen:

We have acted as U.S. counsel to CDT Environmental Technology Investment Holdings Limited (the "Company"), in connection with the Registration Statement on Form F-1 (File No. 333-252127) (as amended, the "Registration Statement") filed with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Securities Act"), for the registration of 2,500,000 ordinary shares, par value $0.0025 per share, which includes up to 300,000 ordinary shares, par value $0.0025 per share, issuable upon exercise of an over-allotment option granted to the underwriters by the Company, and up to 200,000 ordinary shares, par value $0.0025 per share, underlying warrants issuable to the underwriters upon exercise of such warrants (the "Warrants"), pursuant to the Underwriting Agreement among the Company and the underwriters named therein (the "Underwriting Agreement").

You have requested our opinion as to the matters set forth below in connection with the Registration Statement. For purposes of rendering that opinion, we have examined: (i) the Registration Statement; (ii) the most recent prospectus included in the Registration Statement on file with the Commission as of the date of this opinion letter; (iii) the Underwriting Agreement; (iv) the Warrants; and (v) the records of corporate actions of the Company relating to the Registration Statement, the Underwriting Agreement and the Warrants and matters in connection therewith. We have also made such other investigation as we have deemed appropriate. We have examined and relied upon certificates of public officials and, as to certain matters of fact that are material to our opinion, we have also relied on certificates of officers of the Company.

For purposes of this opinion letter, we have made the assumptions that are customary in opinion letters of this kind, including without limitation: (i) that each document submitted to or reviewed by us is accurate and complete; (ii) that each such document that is an original is authentic and each such document that is a copy conforms to an authentic original; (iii) that all signatures on each such document are genuine; (iv) the legal capacity of all natural persons; (v) that each such document, other than the Warrants with respect to the Company, constitutes a legal, valid, and binding obligation of each party thereto, enforceable against each such party in accordance with its terms; (vi) that there are no documents or agreements by or among any of the parties thereto, other than those referenced in this opinion letter, that could affect the opinion expressed herein and no undisclosed modifications, waivers or amendments (whether written or oral) to any of the documents reviewed by us in connection with this opinion letter; and (vii) that all parties have complied with all state and federal statutes, rules and regulations applicable to them relating to the transactions set forth in the Underwriting Agreement and Warrants. We have further assumed that the Company does not in the future issue or otherwise make unavailable so many ordinary shares that there are insufficient remaining authorized but unissued ordinary shares for issuance pursuant to exercise of the Warrants. We have also assumed that all of the ordinary shares issuable or eligible for issuance pursuant to exercise of the Warrants following the date hereof will be issued for not less than par value. We have not verified any of the foregoing assumptions.

The opinion expressed in this opinion letter is based on the facts in existence and the laws in effect on the date hereof and is limited to (a) the federal laws of the United States of America and (b) the laws of the State of Florida that, in either case and based on our experience, are applicable to transactions of the type contemplated by the Underwriting Agreement and Warrants. Except as expressly set forth in this opinion letter, we are not opining on specialized laws that are not customarily covered in opinion letters of this kind, such as tax, insolvency, antitrust, pension, employee benefit, environmental, intellectual property, banking, consumer lending, insurance, labor, health and safety, anti-money laundering, anti-terrorism and state securities laws, on the Exon-Florio Amendment to the Defense Production Act of 1950, as amended by the Foreign Investment and National Security Act of 2007 and the Foreign Investment Risk Review Modernization Act of 2018, including procedures governing reviews thereunder by the Committee on Foreign Investment in the United States, or on the rules of any self-regulatory organization, securities exchange, contract market, clearing organization or other platform, vehicle or market for trading, processing, clearing or reporting transactions. We are not opining on any other law or the law of any other jurisdiction, including any foreign jurisdiction or any county, municipality or other political subdivision or local governmental agency or authority.

Based on the foregoing, and subject to the foregoing and the additional qualifications and other matters set forth below, it is our opinion that when the Warrants are duly executed and authenticated in accordance with the Underwriting Agreement and when issued, delivered and paid for, as contemplated by the Registration Statement and the Underwriting Agreement, such Warrants will constitute valid and binding obligations of the Company enforceable in accordance with their terms, except: (a) as such enforceability may be limited by bankruptcy, insolvency, orderly liquidation or resolution, fraudulent transfer and conveyance, preference, reorganization, receivership, conservatorship, moratorium, or similar laws affecting the rights and remedies of creditors generally, and by general principles of equity, whether considered in a proceeding at law or equity, including but not limited to principles limiting the availability of specific performance and injunctive relief, and concepts of materiality, reasonableness, good faith and fair dealing; (b) as enforceability of any indemnification or contribution provision may be limited under the federal and state securities laws; and (c) that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to the equitable defenses and to the discretion of the court before which any proceeding therefor may be brought.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to this firm in the Registration Statement under the caption "Legal Matters." In giving our consent, we do not hereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations thereunder.
