US confirms dumping duties on Indian silicomanganese for 2023-24
The U.S. Department of Commerce issued final results of an administrative review of antidumping duties on silicomanganese from India, covering the period May 1, 2023 through April 30, 2024. Maithan Alloys Limited (MAL), the sole producer and exporter reviewed, was found to have made sales of subject merchandise in the United States at less than normal value, confirming dumping and triggering continued duties. Importers sourcing silicomanganese from India must ensure compliance with applicable antidumping tariff rates and consider the anti-dumping margin in landed-cost calculations.

The U.S. Department of Commerce announced on May 18, 2026 the final results of an antidumping duty administrative review covering silicomanganese imports from India during the period May 1, 2023 through April 30, 2024.
Key Finding
Commerce determined that Maithan Alloys Limited (MAL), the sole producer and exporter subject to this review, made sales of subject merchandise in the United States at less than normal value during the period of review. This finding confirms that dumping occurred and substantiates the continued application of antidumping duties.
Who Is Affected
Importers and freight forwarders sourcing silicomanganese (HS Chapter 72, ferroalloys) from India—particularly from MAL—are directly affected. Any U.S. importer clearing silicomanganese from Indian suppliers must apply the applicable antidumping duty margin to their landed-cost calculations. The final determination establishes the duty rate that will be assessed on future entries.
"Commerce determines that the sole producer and/or exporter subject to this review, Maithan Alloys Limited (MAL), made sales of subject merchandise in the United States at less than normal value during the period of review (POR), May 1, 2023, through April 30, 2024."

Administrative reviews of antidumping orders are conducted annually to reassess duty margins based on actual import data and pricing. This final determination concludes the review cycle for the 2023-24 period and sets the margin that will apply to future entries of silicomanganese from MAL and potentially other Indian producers if they are subject to the original order.
What this means for shippers
If you import silicomanganese from India, recalculate your landed cost immediately using the final antidumping duty rate confirmed in this review. Verify that your supplier is not MAL or obtain confirmation of the applicable margin from your customs broker. Failure to account for the correct antidumping duty will result in underbond shipments and penalty exposure. Update your cost models and pricing before placing new orders.
