What changed

The U.S. International Trade Commission (USITC) has issued a final determination in its five-year (sunset) review of the antidumping order on electrolytic manganese dioxide from China. The Commission found that revoking the order would be likely to lead to the continuation or recurrence of material injury, meaning the existing antidumping order will remain in effect. This decision is based on the Commission's review process, which includes evaluating responses from interested parties and available data.

This determination means that antidumping duties will continue to be applied to imports of electrolytic manganese dioxide from China. Importers and exporters involved in this trade should be aware that the existing trade restrictions and associated duties remain in place. The full report detailing the Commission's findings will be available by March 18, 2026.

Contact: Jennifer Andberg, 202-205-1819 USITC Makes Determination in Five-Year (Sunset) Review Concerning Electrolytic Manganese Dioxide from China

The U.S. International Trade Commission (Commission or USITC) today determined that revoking the existing antidumping order on imports of electrolytic manganese dioxide from China would be likely to lead to continuation or recurrence of material injury within a reasonably foreseeable time.

As a result of the Commission’s affirmative determination, the existing order on imports of this product from China will remain in place.

Chair Amy A. Karpel and Commissioners David S. Johanson and Jason E. Kearns voted in the affirmative.

Today’s action comes under the five-year (sunset) review process required by the Uruguay Round Agreements Act. See the attached page for background on these five-year (sunset) reviews.

The Commission’s public report, Electrolytic Manganese Dioxide from China (Inv. No. 731-TA- 1125 (Third Review)), USITC Publication 5703, February 2026), will contain the views of the Commission and information developed during the review.

The report will be available by March 18,2026; when available, it may be accessed on the USITC website.

BACKGROUND

The Uruguay Round Agreements Act requires the Department of Commerce to revoke an antidumping or countervailing duty order, or terminate a suspension agreement, after five years unless the Department of Commerce and the USITC determine that revoking the order or terminating the suspension agreement would be likely to lead to continuation or recurrence of dumping or subsidies (Commerce) and of material injury (USITC) within a reasonably foreseeable time.

The Commission’s institution notice in a five-year review requests that interested parties file responses with the Commission concerning the likely effects of revoking the order under review as well as other information. Generally, within 95 days from institution, the Commission will determine whether the responses it has received reflect an adequate or inadequate level of interest in a full review. If responses to the USITC’s notice of institution are adequate, or if other circumstances warrant a full review, the Commission conducts a full review, which includes a public hearing and issuance of questionnaires.

The Commission generally does not hold a hearing or conduct further investigative activities in expedited reviews. Commissioners base their injury determination in expedited reviews on the facts available, including the Commission’s prior injury and review determinations, responses received to its notice of institution, data collected by staff in connection with the reviews, and information provided by the Department of Commerce.

The five-year (sunset) review concerning electrolytic manganese dioxide from China was instituted on June 2, 2025.

On September 5, 2025, the Commission determined to conduct an expedited five-year review. Chair Amy A. Karpel and Commissioners David S. Johanson and Jason E. Kearns concluded that the domestic interested party group response was adequate and the respondent interested party group response was inadequate, and voted for an expedited review.

A record of the Commission’s vote to conduct an expedited review is available on the investigations page for ** Electrolytic Manganese Dioxide from China; Inv. No. 731-TA- 1125 (Third Review) .
