Methionine — France — A-427-831

A measure titled “Methionine” and identified as AD/CVD concerns imported methionine products that may fall within the legal scope of an antidumping duty (AD) or countervailing duty (CVD) proceeding. AD duties address imports sold at less than normal value, while CVD duties address benefits a foreign government provides to producers or exporters. These duties are separate from ordinary customs duty rates.

The measure typically affects importers, manufacturers, distributors, and other parties bringing covered merchandise into the United States from the countries identified in the official measure. Whether a shipment is covered depends on the product’s technical characteristics, country of origin, producer or exporter, and the measure’s written scope—not just the product name or its HTS classification. If covered, the importer may need to pay additional cash deposits at entry and could face later duty assessment, recordkeeping, and compliance obligations.

What to check

• Read the official scope language and compare the product’s composition, form, packaging, and intended use; do not rely on the product name alone.
• Confirm the country of origin and identify the producer and exporter, because AD/CVD treatment can vary by country and company.
• Verify the correct HTS classification, but treat it as an identification aid rather than proof that the merchandise is inside or outside the scope.
• Check current official instructions for applicable cash-deposit requirements, exclusions, liquidation treatment, and any importer certification requirements.
• Ask a customs broker or trade counsel to review uncertain products and consider requesting a formal scope determination when the written scope is ambiguous.
