Legal Opinion on Certain PRC Legal Matters 2024

Ladies and Gentlemen:

We are qualified lawyers of the People's Republic of China (the “PRC”, for the purpose of this opinion, excluding the Hong Kong Special Administrative Region, Macau Special Administrative Region and Taiwan) and as such are qualified to issue this opinion according to the laws and regulations of the PRC.

We have acted as legal counsel as to PRC Laws to Tantech Holdings Ltd.. (“Tantech”, or the “Company”), which is not a Chinese operating company but a British Virgin Islands holding company with operations conducted by our Subsidiaries established in PRC, in connection with the Form F-1 Registration Statement including all amendments or supplements thereto (“Registration Statement”) of the Company relating to the registration and resale of up to 61,313,874 Common Share of the Company.

Our opinion is subject to the following qualifications:

(a) This opinion is subject to the restrictions of the legally vested discretion of any competent PRC legislative, administrative or judicial bodies in exercising their authority in the PRC.

(b) This opinion relates only to PRC Laws and we express no opinion as to any laws other than PRC Laws.

(c) This opinion is intended to be used in the context which is specially referred to herein and each section should be considered as a whole and no part should be extracted and referred to independently.

(d) This opinion is issued based on our understanding of the current PRC Laws. For matters not explicitly provided under the current PRC Laws, the interpretation, implementation and application of the specific requirements under the PRC Laws are subject to the final discretion of competent PRC legislative, administrative and judicial authorities.

(e) For the purpose of the filing of the Registration Statement, we consent to the filing with the SEC of this letter as an exhibit to 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 Act or the regulations promulgated thereunder.

Based upon and subject to the foregoing, we are of the opinion that:

(i) VIE Structure. In August 2021, the board of directors the Company had made decision and dissolved the variable interest entity (“VIE”) structure. Based on our understanding of the PRC Laws, we are of the opinion that according to the PRC Laws currently in effect, as of the date of this letter, the Company may face no relative risks, such as penalties associated with the prior VIE structure.

However, we cannot guarantee the Company will not face legal or administrative regulatory risks in the future that if PRC laws and regulations change, or the interpretation or enforcement of PRC laws and regulations changes and the VIE structure is retroactively disallowed.

(ii) Business. Currently, the Company mainly provides bamboo-based charcoal products and electric Motors vehicles which are not stipulated on the Special Administrative Measures for the Access of Foreign Investment (Negative List) (2022 Version) (the “2022 Negative List”) promulgated by the Ministry of Commerce of the People’s Republic of China (“MOFCOM”) and The National Development and Reform Commission of the PRC which took effect on March 12, 2022. Therefore, the PRC subsidiaries of the Company are able to conduct their current business without being subject to restrictions imposed by the foreign investment laws and regulations of the PRC.

(iii) M&A Rules. The M&A Rules purport to require offshore special purpose vehicles that are controlled by PRC companies or individuals and that have been formed for the purpose of seeking a public listing on an overseas stock exchange through acquisitions of PRC domestic companies or assets to obtain CSRC approval prior to publicly listing their securities on an overseas stock exchange. In this letter, “M&A Rules” means the Rules on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors jointly promulgated by the MOFCOM, the State Assets Supervision and Administration Commission, the State Administration of Taxation, the State Administration of Industry and Commerce, China Securities Regulatory Commission (“CSRC”) and the State Administration of Foreign Exchange of the PRC on August 8, 2006 and as amended by the MOFCOM on June 22, 2009.

Except as disclosed in the statements set forth in the Registration Statement under the caption “Risk Factors—Risks Related to Doing Business in China— We are required to complete filing procedures with the CSRC in connection with securities issuance and may be subject to approval, filing or other procedures with other Chinese regulatory authorities under PRC law; we cannot predict whether we will be able, or how long it will take us, to obtain such approval or complete such filing or other procedures” and based on our understanding of the PRC Laws, we are of the opinion that the Company is not required to submit an application to the CSRC for the approval under the M&A rules because (i) the CSRC currently has not issued any definitive rule or interpretation concerning whether offerings like the Company’s under the Registration Statement are subject to this regulation; (ii) the wholly-owned PRC subsidiary of the Company was incorporated as a foreign-invested enterprise by means of foreign direct investments rather than by merger with or acquisition of any PRC domestic companies as defined under the M&A Rules. However, there can be no assurance that the relevant governmental agencies of PRC, including the CSRC, would reach the same conclusion.

(iv) Overseas Listing Regulations. We have advised the Company as to the content of the Overseas Listing Regulations, which are applicable to overseas securities offerings and/or listings conducted by issuers who are (i) PRC domestic companies and (ii) companies incorporated overseas with substantial operations in the PRC and stipulate that such issuer shall fulfill the filing procedures within three working days after it makes an application for initial public offering and listing in an overseas stock market. Among other things, if an overseas listed issuer intends to effect any follow-on offering in an overseas stock market, it should, through its major operating entity incorporated in the PRC, submit filing materials to the CSRC within three working days after the completion of the offering. The required filing materials shall include, but not be limited to, (1) filing report and relevant commitment letter and (2) domestic legal opinions. The Overseas Listing Regulations stipulate the legal consequences for breaches, including failure to fulfill filing obligations or engaging in fraudulent filing behavior, which may result in a fine ranging from RMB1 million to RMB10 million, and in cases of severe violations, the relevant responsible persons may also be barred from entering the securities market.

(V) Cybersecurity Review Measures. On July 10, 2021, the Cyberspace Administration of China issued the Cybersecurity Review Measures (revised draft for public comments), which proposed to authorize the relevant government authorities to conduct cybersecurity review on a range of activities that affect or may affect national security. The revised Cybersecurity Review Measures took effect on February 15, 2022. The revised Cybersecurity Review Measures expand the cybersecurity review to data processing operators in possession of personal information of over 1 million users if the operators intend to list their securities in a foreign country. The Company mainly provides bamboo-based charcoal products and electric Motors vehicles which are not stipulated on the Special Management Measures for Cross border Service Trade (Negative List) (2024 Version) and the Special Management Measures for Cross border Service Trade in Pilot Free Trade Zones (Negative List) (2024 Version), which were promulgated by the Ministry of Commerce of the People’s Republic of China effective on April 21, 2024. Therefore, the Company is not and will not be conduct business operations subject to the 2024 Negative Lists regulated by the aforesaid regulations.

Except as disclosed in the statements set forth in the Registration Statement under the caption “Risk Factors—Risks Related to Doing Business in China—The Chinese government exerts substantial influence over the manner in which we must conduct our business activities and may intervene or influence our operations at any time, which could result in a material change in our operations and the value of our Common Shares.” and “Risk Factors—Risks Related to Doing Business in China— We are required to complete filing procedures with the CSRC in connection with securities issuance and may be subject to approval, filing or other procedures with other Chinese regulatory authorities under PRC law; we cannot predict whether we will be able, or how long it will take us, to obtain such approval or complete such filing or other procedures” and based on our understanding of the PRC Laws, we are of the opinion that based on the Chinese laws and regulations currently in effect, as of the date of this letter, the Company is not required to submit an application to the Cyberspace Administration of China for the approval of the offerings because the cybersecurity review requirement under the revised Cybersecurity Review Measures for online platform operators in possession of personal information of over one million users going public in a foreign country does not apply to the Company or any of its PRC subsidiaries.
