Dear Sirs

Huarui International New Material Limited 华瑞国际新材料有限公司 (the Company)

We are lawyers qualified to practise in the British Virgin Islands and have acted as British Virgin Islands legal advisers to the Company in connection with the Company’s registration statement on Form F-1, including all amendments or supplements thereto, and accompanying prospectus filed with the Securities and Exchange Commission (the Commission) under the United States Securities Act of 1933, as amended (the Securities Act) (the Registration Statement), relating to the offering by the Company of certain of its ordinary shares of par value US$0.0083 per share (the IPO Shares), the warrants to be issued to the underwriters (the Underwriter’s Warrants), and the ordinary shares underlying the Underwriter’s Warrants (the Underlying Shares, together with the IPO Shares and the Underwriter’s Warrants, the Shares).

We are furnishing this opinion as Exhibit 5.1 to the Registration Statement.

For the purposes of giving this opinion, we have examined the Documents (as defined in Schedule 1) which we regard as necessary in order to issue this opinion. We have not examined any other documents, official or corporate records or external or internal registers and have not undertaken or been instructed to undertake any further enquiry or due diligence in relation to the transaction which is the subject of this opinion.

In giving this opinion we have relied upon the assumptions set out in Schedule 2 which we have not independently verified.

Based solely upon the foregoing examinations and assumptions and upon such searches as we have conducted and having regard to legal considerations which we deem relevant, and subject to the qualifications set out in Schedule 3, we are of the opinion that under the laws of the British Virgin Islands:

1 Existence and Good Standing. The Company is a company duly incorporated with limited liability, and is validly existing and in good standing under the laws of the British Virgin Islands. The Company is a separate legal entity and is subject to suit in its own name.

2 Authorised Shares. Based on our review of the M&A (as defined in Schedule 1), the Company is authorised to issue a maximum of 100,000,000 ordinary shares of US$0.0083 par value each of a single class.

3 Valid Issuance of Shares. The allotment and issue of the Shares as contemplated by the Registration Statement have been duly authorised and, when allotted, issued and fully paid for in accordance with the Registration Statement, and when the names of the shareholders are entered in the register of members of the Company, the Shares will be validly issued, allotted, fully paid and non-assessable, and there will be no further obligation of the holders of any of the Shares to make any further payment to the Company in respect of such Shares.

4 British Virgin Islands Law. The statements under the caption “Taxation” in the prospectus forming part of the Registration Statement, to the extent that they constitute statements of British Virgin Islands law, are accurate in all material respects as at the date of this opinion and such statements constitute our opinion.

This opinion is confined to the matters expressly opined on herein and given on the basis of the laws of the British Virgin Islands as they are in force and applied by the British Virgin Islands courts at the date of this opinion. We have made no investigation of, and express no opinion on, the laws of any other jurisdiction. Except as specifically stated herein, we express no opinion as to matters of fact.

In connection with the above opinion, we hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference made to this firm in the Registration Statement under the headings “Enforceability of Civil Liabilities”, “Taxation” and “Legal Matters” and elsewhere in the prospectus included in the Registration Statement. In giving such consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the U.S. Securities Act of 1933, as amended, or the Rules and Regulations of the Commission thereunder.

This opinion is limited to the matters referred to herein and shall not be construed as extending to any other matter or document not referred to herein.

This opinion shall be construed in accordance with the laws of the British Virgin Islands.

Yours faithfully
