On September 16, 2026, HCL, PLLC (“HCL”) notified the Audit Committee (the “Audit Committee”) of the Board of Directors (the “Board”) of IT Tech Packaging, Inc. (the “Company”) of its resignation as the Company’s independent registered public accounting firm, effective September 16, 2026.

The Company had engaged HCL on September 2, 2026, as approved by the Audit Committee, to audit the Company’s consolidated financial statements for the fiscal year ended December 31, 2025. HCL did not issue any audit report on the Company’s financial statements during the period from September 2, 2026 (the date of engagement) through September 16, 2026 (the date of resignation). Accordingly, there were no audit reports issued by HCL on the Company’s financial statements for either of the two most recent fiscal years or any subsequent interim period that contained an adverse opinion or disclaimer of opinion, or were qualified or modified as to uncertainty, audit scope, or accounting principles.

Based on the procedures performed by HCL during its period of engagement from September 2, 2026 through the date of its resignation, no disagreements arose between the Company and HCL on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure that, if not resolved to HCL’s satisfaction, would have caused HCL to make reference to the subject matter of the disagreement in connection with its report issued in connection with the audit of the Company’s financial statements.

Based on the procedures performed by HCL during its period of engagement from September 2, 2026 through the date of its resignation, HCL did not identify any “reportable events” as defined in Item 304(a)(1)(v) of Regulation S-K.

The Company has provided HCL with a copy of the disclosures made in this Current Report on Form 8-K and has requested that HCL furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether or not HCL agrees with the statements made herein. A copy of HCL’s letter, dated September 16, 2026, is filed as Exhibit 16.1 to this Current Report on Form 8-K.

As of the date of this Current Report, the Company has not engaged a successor independent registered public accounting firm. The Company intends to engage a new auditor promptly.

(d) Exhibits.
