Lysine — China — C-570-216

A measure labeled “Lysine” with type “AD/CVD” concerns possible trade-remedy duties on covered lysine products imported into the United States. “AD” means antidumping: duties may apply when merchandise from a specified country is sold in the U.S. at less than its normal value. “CVD” means countervailing duty: duties may apply when a foreign government provides subsidies that benefit the merchandise. These duties are separate from ordinary customs duty and may apply in addition to it.

The measure typically affects importers of the covered product from the countries, producers, exporters, and product descriptions identified in the official scope. Coverage depends on the merchandise’s physical characteristics and intended use, not only its commercial name or tariff classification. An importer should verify the product’s “scope,” “country of origin,” “producer/exporter,” and applicable HTSUS classification because AD/CVD liability can involve more than simply finding an HTSUS number. These measures can affect landed cost, entry filing, cash deposits, recordkeeping, and later duty liability. When the scope or facts are unclear, obtain guidance from a customs broker or trade-remedy professional.

What to check

• Read the official scope description and compare it with the product’s ingredients, form, purity, packaging, and intended use—not just its product name.
• Confirm the country of origin and identify the actual manufacturer, producer, and exporter; treatment can vary by these parties and by country.
• Check the official AD/CVD instructions and current entry requirements for the relevant HTSUS classification, including whether separate case identifiers or cash-deposit instructions are required.
• Ask your customs broker to review whether the product is subject to AD, CVD, both, or neither, and whether an exclusion or scope ruling may apply.
• Keep purchase orders, production records, origin documents, supplier certifications, and product specifications in case Customs or the administering agency reviews the entry.
