Tungsten Ore Concentrates — China — A-570-811

An AD/CVD measure concerning tungsten ore concentrates is a trade-remedy action. “AD” means antidumping: it addresses imports sold at less than normal value. “CVD” means countervailing duty: it addresses benefits from government subsidies. These duties are separate from ordinary customs duty and may apply in addition to it.

The measure typically concerns imported tungsten-bearing mineral material that meets the product definition in the official scope. It may affect miners, exporters, processors, distributors, and US importers. The product’s tariff classification, country of origin, exporter, producer, physical form, and processing history can all matter. An HTS classification is useful for screening, but the written scope controls whether the merchandise is covered; confirmation from official instructions or a qualified customs professional may be necessary.

What to check

• Read the official scope carefully, including included materials, exclusions, chemical or physical specifications, and processing conditions.
• Confirm the product’s country of origin and identify every producer and exporter in the transaction; AD/CVD treatment can depend on these parties.
• Use the appropriate HTS classification for entry documentation, but do not treat an HTS number alone as proof that the product is covered or excluded.
• Ask your customs broker or trade counsel to verify the applicable cash-deposit instructions, entry requirements, and any certification or reporting obligations before importing.
• Keep product specifications, test results, invoices, bills of lading, origin records, and producer/exporter information that support your scope and classification analysis.
