Carboxymethylcellulose — Mexico — A-201-834

A measure labeled “Carboxymethylcellulose” and marked AD/CVD concerns a trade-remedy proceeding involving this product. AD means antidumping, which addresses allegations that imported goods are sold in the United States at less than fair value. CVD means countervailing duty, which addresses alleged government subsidies benefiting foreign producers or exporters. These duties are separate from ordinary customs duty and may be assessed in addition to it.

The measure typically affects U.S. importers bringing covered carboxymethylcellulose from specified countries or producers and exporters. Coverage depends on the legal product description, not just the product’s commercial name or tariff classification. An importer should review the scope, applicable producer or exporter information, entry requirements, and whether the shipment is subject to suspension of liquidation or duty assessment. Because AD/CVD liability can be technical and fact-specific, a customs broker or trade-remedy specialist may be needed.

What to check

• Read the measure’s scope language and compare it with the product’s ingredients, physical form, grade, uses, and specifications—not only its invoice description or HS classification.
• Confirm the country of origin and identify the actual manufacturer, producer, and exporter; AD/CVD treatment can vary by origin and by company.
• Check the official AD/CVD instructions for the relevant entry type, cash-deposit or bonding requirements, and any certification or documentation obligations.
• Ask your customs broker or trade counsel to review borderline products, mixed shipments, scope exclusions, and possible scope-ruling procedures before importing.
• Keep purchase orders, technical data sheets, composition records, origin documents, and producer/exporter information to support classification, scope, and valuation decisions.
