Electrolytic Manganese Dioxide — Australia — A-602-806

An AD/CVD measure involving Electrolytic Manganese Dioxide (EMD) is a US trade-remedy action. “AD” means antidumping duties, which address goods sold in the US at less than fair value; “CVD” means countervailing duties, which address subsidies provided by a foreign government. These duties are separate from ordinary customs duty and may apply in addition to it.

The measure typically affects US importers, foreign producers and exporters, and sometimes related parties involved in importing EMD or goods covered by the product scope. The product scope—not just the product name or tariff classification—controls coverage. An importer should review the scope language, physical characteristics, chemical composition, uses, and exclusions, because a product can be covered even when its tariff code is not obvious. AD/CVD liability can also involve special entry procedures, importer certifications, and potential additional duties, so classification and scope should be confirmed with official sources or a qualified customs professional.

What to check

• Read the measure’s official product scope and exclusions; do not rely only on the product description or HTSUS classification.
• Confirm the merchandise’s chemical composition, form, specifications, and end use against the scope, including whether it is an intermediate or blended product.
• Check the applicable country of origin, producer, exporter, and supplier; AD/CVD treatment can vary by country and company.
• Verify the correct HTSUS reporting provisions and any AD/CVD case instructions with CBP or a customs broker; an HTSUS number is an indicator, not the final scope decision.
• Keep purchase orders, technical sheets, bills of materials, origin records, and supplier certifications that support classification, origin, and scope analysis.
