#  Electrolytic Manganese Dioxide From the People's Republic of China: Continuation of Antidumping Duty Order

**AGENCY:**

Enforcement and Compliance, International Trade Administration, Department of Commerce.

**SUMMARY:**

As a result of the determinations by the U.S. Department of Commerce (Commerce) and the U.S. International Trade Commission (ITC) that revocation of the antidumping duty (AD) order on electrolytic manganese dioxide from the People's Republic of China (China) would likely lead to the continuation or recurrence of dumping and material injury to an industry in the United States, Commerce is publishing a notice of continuation of this AD order.

**DATES:**

Applicable February 23, 2026.

**FOR FURTHER INFORMATION CONTACT:**

David De Falco, Trade Agreements Policy and Negotiations, Enforcement and Compliance, International Trade Administration, U.S. Department of Commerce, 1401 Constitution Avenue NW, Washington, DC 20230; telephone: (202) 482-2178.

**SUPPLEMENTARY INFORMATION:**

**Background**

On October 7, 2008, Commerce published in the *Federal Register* the AD order on electrolytic manganese dioxide from China. [^1] On June 2, 2025, the ITC instituted, [^2] and Commerce initiated, [^3] the third sunset review of the *Order,* pursuant to section 751(c) of the Tariff Act of 1930, as amended (the Act).  As a result of its review, Commerce determined that revocation of the *Order* would likely lead to the continuation or recurrence of dumping, and therefore, notified the ITC of the magnitude of the margins of dumping likely to prevail should the *Order* be revoked. [^4]

[^2]*See Electrolytic Manganese Dioxide from China; Institution of a Five-Year Review,* 90 FR 23367 (June 2, 2025).

[^3]*See Initiation of Five-Year (Sunset) Reviews,* 90 FR 23310 (June 2, 2025).

[^4]*See Electrolytic Manganese Dioxide From the People's Republic of China: Final Results of the Expedited Third Sunset Review of the Antidumping Duty Order,* 90 FR 45188 (September 19, 2025), and accompanying Issues and Decision Memorandum.

On February 23, 2026, the ITC published its determination, pursuant to sections 751(c) and 752(a) of the Act, that revocation of the *Order* would likely lead to continuation or recurrence of material injury to an industry in the United States within a reasonably foreseeable time. [^5]

[^5]*See Electrolytic Manganese Dioxide from China; Determination,* 91 FR 8521 (February 23, 2026) ( *ITC Final Determination* ).

**Scope of the Order**

The merchandise covered by this *Order* includes all manganese dioxide (MnO2) that has been manufactured in an electrolysis process, whether in powder, chip, or plate form. Excluded from the scope are natural manganese dioxide (NMD) and chemical manganese dioxide (CMD). The merchandise subject to this *Order* is classified in the Harmonized Tariff Schedule of the United States (HTSUS) at subheading 2820.10.00.00. While the HTSUS subheading is provided for convenience and customs purposes, the written description of the scope of this *Order* is dispositive.

**Continuation of the Order**

As a result of the determinations by Commerce and the ITC that revocation of the *Order* would likely lead to continuation or recurrence of dumping and material injury to an industry in the United States, pursuant to section 751(d)(2) of the Act, Commerce hereby orders the continuation of the *Order.* U.S. Customs and Border Protection will continue to collect AD cash deposits at the rates in effect at the time of entry for all imports of subject merchandise.

The effective date of the continuation of the *Order* will be February 23, 2026. [^6] Pursuant to section 751(c)(2) of the Act and 19 CFR 351.218(c)(2), Commerce intends to initiate the next five-year reviews of the *Order* not later than 30 days prior to fifth anniversary of the date of the last determination by the ITC.

[^6]*See ITC Final Determination.*

**Administrative Protective Order (APO)**

Timely written notification of the return or destruction of APO materials, or conversion to judicial protective order, is hereby requested. Failure to comply with the regulations and terms of an APO is a violation which is subject to sanction.

**Notification to Interested Parties**

This five-year (sunset) review and this notice are in accordance with sections 751(c) and 751(d)(2) of the Act and published in accordance with section 777(i) of the Act, and 19 CFR 351.218(f)(4).
