Tantech Holdings Ltd

1,891,307 Common Shares

Warrants to Purchase 1,078,045 Common Shares

1,078,045 Common Shares Issuable upon Exercise of the Warrants

Pursuant to this prospectus supplement and the accompanying prospectus, we are offering up to 1,891,307 common shares directly to selected investors. The purchasers in this offering will also receive warrants to initially purchase an aggregate of 945,654 common shares with a per share exercise price of $4.25. The warrants are exercisable immediately as of the date of issuance at an exercise price of $4.25 per share of our common shares and expire five years from the date of issuance. A holder of the warrants also will have the right to exercise its warrants on a cashless basis if the registration statement or prospectus contained therein is not available for the issuance of the common shares issuable upon exercise thereof.

For a more detailed description of the common shares and warrants, see the section entitled “Description of Our Securities We Are Offering” beginning on page S-7. There is no established public trading market for the warrants, and we do not expect a market to develop. We do not intend to apply to list the warrants on any securities exchange.

Our common shares are currently traded on the NASDAQ Capital Market under the symbol “TANH.” On September 26, 2017, the closing sale price of our common shares was $4.22 per share.

As of the date of this prospectus supplement, the aggregate market value of our outstanding common shares held by non-affiliates was approximately $42,254,860 based on 26,811,935 outstanding common shares, of which 10,013,000 are held by non-affiliates, and a per share price of $4.22, which was the last reported price on the NASDAQ Capital Market of our common shares on September 26, 2017. We have not offered any securities pursuant to General Instruction I.B.5. of Form F-3 during the prior 12 calendar month period that ends on and includes the date of this prospectus supplement.

We have retained FT Global Capital, Inc. to act as the exclusive placement agent to use its best efforts to solicit offers from investors to purchase the securities in this offering. The placement agent has no obligation to buy any securities from us or to arrange for the purchase or sale of any specific number or dollar amount of securities. The placement agent is not purchasing or selling any common shares or warrants in this offering. We will pay the placement agent a fee equal to the sum of 7% of the aggregate purchase price paid by investors placed by the placement agent. Additionally, we will issue to the placement agent warrants to purchase 132,391 common shares on substantially the same terms as the warrants sold in this offering, except that the placement agent warrants are exercisable at $4.675 per share, shall not be exercisable for a period of 180 days and shall expire five years after the effective date of this offering. The placement agent warrant and common shares underlying such warrant are being registered herein.

We estimate the total expenses of this offering, excluding the placement agency fees, will be approximately $85,000. Because there is no minimum offering amount, the actual offering amount, the placement agency fees and net proceeds to us, if any, in this offering may be substantially less than the total offering amounts set forth above. We are not required to sell any specific number or dollar amount of the securities offered in this offering. Assuming we complete the maximum offering, the net proceeds to us from this offering will be approximately $6.07 million. We expect to deliver the shares and warrants to the purchasers on or before September 29, 2017.

Investing in our securities involves a high degree of risk. You should purchase our securities only if you can afford a complete loss of your investment. See “ Risk Factors ” beginning on page S-5 of this prospectus supplement. Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

ABOUT THIS PROSPECTUS SUPPLEMENT

On February 27, 2017, we filed with the SEC a registration statement on Form F-3 (File No. 333-213240) utilizing a shelf registration process relating to the securities described in this prospectus supplement, which registration statement was declared effective on March 9, 2017. Under this shelf registration process, we may, from time to time, sell up to $150 million in the aggregate of common shares, share purchase contracts, share purchase units, warrants, rights and units, of which approximately $143.5 million will remain available for sale following the offering and as of the date of this prospectus supplement, excluding the shares issuable upon exercise of the warrants issued in this offering.

RISK FACTORS

Before you make a decision to invest in our securities, you should consider carefully the risks described below, together with other information in this prospectus supplement, the accompanying prospectus and the information incorporated by reference herein and therein. If any of the following events actually occur, our business, operating results, prospects or financial condition could be materially and adversely affected. This could cause the trading price of our common stock to decline and you may lose all or part of your investment. The risks described below are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also significantly impair our business operations and could result in a complete loss of your investment.

RISKS RELATED TO THIS OFFERING

Since we have some discretion in how we use the proceeds from this offering, we may use the proceeds in ways with which you disagree.

We have not allocated specific amounts of the net proceeds from this offering for any specific purpose. Accordingly, subject to any agreed upon contractual restrictions under the terms of the securities purchase agreement, our management will have some flexibility in applying the net proceeds of this offering. You will be relying on the judgment of our management with regard to the use of these net proceeds, and subject to any agreed upon contractual restrictions under the terms of the purchase agreement, you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. It is possible that the net proceeds will be invested in a way that does not yield a favorable, or any, return for us. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flow.

There is no minimum offering amount required to consummate this offering.

There is no minimum offering amount which must be raised in order for us to consummate this offering. Accordingly, the amount of money raised may not be sufficient for us to meet our business objectives. Moreover, if only a small amount of money is raised, all or substantially all of the offering proceeds may be applied to cover the offering expenses and we will not otherwise benefit from the offering. In addition, because there is no minimum offering amount required, investors will not be entitled to a return of their investment if we are unable to raise sufficient proceeds to meet our business objectives.

You will experience immediate dilution in the book value per share of the common stock you purchase.

Because the price per share of our common stock being offered is substantially higher than the book value per share of our common stock, you will suffer substantial dilution in the net tangible book value of the common stock you purchase in this offering. After giving effect to the sale by us of 1,891,307 shares of common stock in this offering, and based on a public offering price of $3.45 per common share and a net tangible book value per share of our common stock of $2.99 as of December 31, 2016, without giving effect to the potential exercise of the warrants being offered by this prospectus supplement, if you purchase securities in this offering, you will suffer immediate and substantial dilution of $0.46 per share in the net tangible book value of the common stock purchased. See “Dilution” on page S-6 for a more detailed discussion of the dilution you will incur in connection with this offering.

There is no public market for the warrants to purchase common stock in this offering.

There is no established public trading market for the warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the warrants on any securities exchange. Without an active market, the liquidity of the warrants will be limited.

S- 5

USE OF PROCEEDS

We intend to use the net proceeds from this offering for working capital and other general corporate purposes; provided, however, that none of such proceeds will be used, directly or indirectly, (i) for the satisfaction of any of our debt (other than (I) payment of trade payables in our ordinary course of business and consistent with prior practices and (II) the purchase of any of the securities sold in this offering), (ii) for the redemption of any of our securities; or (iii) with respect to any litigation involving us (including, without limitation, (x) any settlement thereof or (y) the payment of any costs or expenses related thereto).

DILUTION

Purchasers of our common shares offered by this prospectus supplement and the accompanying prospectus will experience an immediate dilution in the net tangible book value of their common shares from the offering price of the common shares. The net tangible book value of our common shares as of December 31, 2016 was approximately $80.2 million or $2.99 per share. Net tangible book value per share of our common shares is equal to our net tangible assets (tangible assets less total liabilities) divided by the number of common shares issued and outstanding as of December 31, 2016.

Dilution per share represents the difference between the public offering price per share of our common shares and the adjusted net tangible book value per share of our common shares after giving effect to this offering. After reflecting the sale of 1,891,307 common shares offered by us at the public offering price of $3.45 per share, less placement agent fee and estimated offering expenses, our adjusted net tangible book value per share of our common shares as of December 31, 2016 would have been $3.00 per share. The change represents an immediate increase in net tangible book value per share of our common shares of $0.01 per share to existing stockholders and an immediate dilution of $0.45 per share to new investors purchasing the common shares in this offering. The following table illustrates this per share dilution:

Public offering price per share	$	3.45
Net tangible book value per share as of December 31, 2016		2.99
Increase per share attributable to new investors		0.01

Adjusted net tangible book value per share as of December 31, 2016	$	3.00

Dilution per share to new investors	$	0.45

Unless specifically stated otherwise, the information in this prospectus supplement excludes 1,078,045 common shares issuable upon the exercise of warrants to be issued in this offering (including warrants issued to the placement agent), at a per share exercise price of $4.25 for warrants to be issued to the investors and $4.675 for warrants to be issued to the placement agent.

To the extent that any of these outstanding options or warrants are exercised, there will be further dilution to new investors.

S- 6

DESCRIPTION OF OUR SECURITIES WE ARE OFFERING

Common Shares

For a description of the Common Shares being offered hereby, please see “Description of Share Capital” in the accompanying prospectus.

Warrants

The material terms and provisions of the warrants being offered pursuant to this prospectus supplement and being issued to the investors and placement agent (with some exceptions noted below) are summarized below. The form of warrant will be provided in this offering and will be filed as an exhibit to a Current Report on Form 6-K with the SEC in connection with this offering.

The warrants to be issued to the investors will have an exercise price of $4.25 per share of our common shares. The warrants are exercisable on or after the date of issuance and will terminate five years from the date of issuance. The warrant issuable to the placement agent shall generally be on the same terms and conditions as the warrants sold in this offering, except that the placement agent warrants shall not be exercisable for a period of 180 days and shall expire five years after the effective date of this offering. The exercise price and number of common shares issuable upon exercise is subject to appropriate adjustment upon the occurrence of certain events, including, but not limited to, stock dividends or splits, business combination, sale of assets, similar recapitalization transactions, or other similar transactions. In addition, the exercise price of the warrants is subject to an adjustment in the event that we issue or are deemed to issue common shares for less than the applicable exercise price of the warrant.

There is no established public trading market for the warrants, and we do not expect a market to develop. We do not intend to apply to list the warrants on any securities exchange. Without an active market, the liquidity of the warrants will be limited.

Holders of the warrants may exercise their warrants to purchase common shares on or before the termination date by delivering an exercise notice, appropriately completed and duly signed. Following each exercise of the warrants, the holder is required to pay the exercise price for the number of shares for which the warrant is being exercised in cash. A holder of the warrants also will have the right to exercise its warrants on a cashless basis if the registration statement or prospectus contained therein is not available for the issuance of the common shares issuable upon exercise thereof. Warrants may be exercised in whole or in part, and any portion of a warrant not exercised prior to the termination date shall be and become void and of no value. The absence of an effective registration statement or applicable exemption from registration does not alleviate our obligation to deliver common shares issuable upon exercise of a warrant.

Upon the holder’s exercise of a warrant, we will issue the common shares issuable upon exercise of the warrant within three trading days of our receipt of notice of exercise, subject to receipt of payment of the aggregate exercise price therefor.

The common shares issuable on exercise of the warrants are duly and validly authorized and will be, when issued, delivered and paid for in accordance with the warrants, issued and fully paid and non-assessable. We will authorize and reserve common shares equal at least one hundred twenty-five percent (125%) of the number of common shares issuable upon exercise of all outstanding warrants.

If, at any time a warrant is outstanding, we consummate any fundamental transaction, as described in the warrants and generally including any consolidation or merger into another corporation, or the sale of all or substantially all of our assets, or other transaction in which our common shares is converted into or exchanged for other securities or other consideration, the holder of any warrants will thereafter receive, the securities or other consideration to which a holder of the number of common shares then deliverable upon the exercise or exchange of such warrants would have been entitled upon such consolidation or merger or other transaction. Additionally, in the event of a fundamental transaction, each warrant holder will have the right to require us, or our successor, to repurchase the warrants for an amount equal to the Black-Scholes value of the remaining unexercised portion of the warrant on the terms set forth in the warrant.

S- 7

The exercisability of the warrants may be limited in certain circumstances if, after giving effect to such exercise, the holder or any of its affiliates would beneficially own (as determined pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder) more than 4.99% of our common shares.

In the event the volume weighted average price per share of our common shares exceeds 300% of the initial exercise price of the warrants for fifteen consecutive trading days, we may be eligible to redeem all, but not less than all, of the warrants by delivering an irrevocable notice of our intention to so redeem the warrants. Subject to certain circumstances in which we may be unable to redeem the warrants, a redemption will require us to pay the difference between the initial issuance price and the highest volume weighted average price on any trading day within a specified period.

THE HOLDER OF A WARRANT WILL NOT POSSESS ANY RIGHTS AS A STOCKHOLDER UNDER THAT WARRANT UNTIL THE HOLDER EXERCISES THE WARRANT. THE WARRANTS MAY BE TRANSFERRED INDEPENDENT OF THE COMMON SHARES WITH WHICH THEY WERE ISSUED, SUBJECT TO APPLICABLE LAWS.

S- 8

PLAN OF DISTRIBUTION

Pursuant to an agreement dated September 18, 2017 (the “ Agreement ”), we have engaged FT Global Capital, Inc. (the “ Placement Agent ”), to act as our exclusive placement agent in connection with this offering of our securities pursuant to this prospectus supplement and accompanying prospectus. The Agreement is attached as an exhibit to our Current Report on Form 6-K filed with the SEC in connection with this offering.

Under the terms of the Agreement, the Placement Agent has agreed to be our placement agent, on a reasonable best efforts basis, in connection with the issuance and sale by us of our common shares and warrants in this takedown from our shelf registration statement. The terms of this offering were subject to market conditions and negotiations between us, the Placement Agent and prospective investors. The Agreement does not give rise to any commitment by the Placement Agent to purchase any of our common shares or warrants, and the Placement Agent will have no authority to bind us by virtue of the Agreement for this offering. Further, the Placement Agent does not guarantee that it will be able to raise new capital in any prospective offering. There is no requirement that any minimum number of securities or dollar amount of securities be sold in this offering and there can be no assurance that we will sell all or any of the securities being offered. As described below, we will enter into a purchase agreement directly with each investor in connection with this offering and we may not sell the entire amount of securities offered pursuant to this prospectus supplement.

The Placement Agent may be deemed to be an underwriter within the meaning of Section 2(a)(11) of the Securities Act, and any commissions received by it and any profit realized on the resale of the securities sold by it while acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. As an underwriter, the Placement Agent would be required to comply with the requirements of the Securities Act and the Exchange Act, including, without limitation, Rule 415(a)(4) under the Securities Act and Rule 10b-5 and Regulation M under the Exchange Act. These rules and regulations may limit the timing of purchases and sales of common shares by the Placement Agent acting as principal. Under these rules and regulations, the Placement Agent: (1) may not engage in any stabilization activity in connection with our securities; and (2) may not bid for or purchase any of our securities or attempt to induce any person to purchase any of our securities, other than as permitted under the Exchange Act, until it has completed its participation in the distribution.

We will enter into a Securities Purchase Agreement with the purchasers purchasing the securities being issued pursuant to this offering. The form of the Securities Purchase Agreement is attached as an exhibit to our Current Report on Form 6-K filed with the SEC in connection with this offering. The closing of this offering will take place on or before September 29, 2017, and the following will occur: (1) we will receive funds in the amount of the aggregate purchase price; (2) the Placement Agent will receive the placement agent fees in accordance with the terms of the Agreement; and (3) we will deliver the common shares and warrants.

Commissions and Offering Expenses

Upon the closing of this offering, we have agreed to pay the Placement Agent a cash fee equal to 7% of the aggregate purchase price of the common shares and warrants sold under this prospectus supplement. We have also agreed to reimburse the Placement Agent for certain expenses, including up to $15,000 for fees and expenses related to “blue sky” counsel and up to $25,000 for additional legal expenses.

Placement Agent Warrants

We have agreed to issue to the Placement Agent a warrant to purchase a number of common shares equal to 7.0% of the aggregate number of common shares sold in this offering, which warrant will have an exercise price of $4.675 per share and will terminate on the five-year anniversary of the effective date of the offering. The Placement Agent warrants will have substantially the same terms as the warrants being sold in the offering. Pursuant to FINRA Rule 5110(g), the Placement Agent warrants and any shares issued upon exercise of the Placement Agent warrants shall not be sold, transferred, assigned, pledged, or hypothecated, or be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of the securities by any person for a period of 180 days immediately following the date of effectiveness or commencement of sales of this offering, except the transfer of any security: (i) by operation of law or by reason of our reorganization; (ii) to any FINRA member firm participating in the offering and the officers or partners thereof, if all securities so transferred remain subject to the lock-up restriction set forth above for the remainder of the time period; (iii) if the aggregate amount of our securities held by the placement agent or related persons do not exceed 1% of the securities being offered; (iv) that is beneficially owned on a pro-rata basis by all equity owners of an investment fund, provided that no participating member manages or otherwise directs investments by the fund and the participating members in the aggregate do not own more than 10% of the equity in the fund; or (v) the exercise or conversion of any security, if all securities remain subject to the lock-up restriction set forth above for the remainder of the time period.

DISCLOSURE OF COMMISSION POSITION ON
INDEMNIFICATION FOR SECURITIES LAW VIOLATIONS

British Virgin Islands law does not limit the extent to which a company’s articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the British Virgin Islands courts to be contrary to public policy, 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, officers and liquidators 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 director, officer or liquidator. To be entitled to indemnification, these persons must have acted honestly and in good faith with a view to our best interest and, in the case of criminal proceedings, they must have had no reasonable cause to believe their conduct was unlawful.

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 Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.
