Electrolytic Manganese Dioxide — China — A-570-919

An AD/CVD measure covering Electrolytic Manganese Dioxide (EMD) is a US trade remedy that may apply when imported EMD is determined to be dumped (sold below a fair-value benchmark) and/or to benefit from countervailable subsidies. “AD” means antidumping; “CVD” means countervailing duty. These measures are generally tied to specified exporting countries and to the product description in the official scope, not simply to a product name.

The measure typically affects manufacturers, exporters, importers of record, and US buyers bringing covered EMD into the United States. It matters because an importer may need to provide additional entry information, pay AD/CVD cash deposits, and manage potential liability for later duty assessments. The Harmonized Tariff Schedule (HTS) classification can help identify entries, but the written scope and official agency instructions control; a customs broker or trade counsel may be needed for a difficult scope question.

What to check

• Compare the product’s physical characteristics, composition, packaging, and intended use with the official scope language for the EMD measure.
• Confirm the country of origin and export country; do not assume the supplier’s location alone determines whether the measure applies.
• Review the HTS classification as an identification aid, but do not rely on the tariff number instead of the written scope.
• Ask your customs broker to verify the required entry codes, cash-deposit treatment, and documentation before importing potentially covered merchandise.
• Keep purchase records, production information, origin documents, and product specifications in case Commerce or CBP later reviews the entry or assesses duties.
