Emulsion Styrene-Butadiene Rubber — Brazil — A-351-849

“Emulsion Styrene-Butadiene Rubber” refers to a rubber product made by polymerizing styrene and butadiene in an emulsion process. In a trade-measure context, the product description is part of the measure’s scope: coverage depends on the product’s physical and chemical characteristics, not just the name used on an invoice. The applicable tariff classification (HTSUS subheading) can help identify the product, but it does not by itself decide whether the product is covered.

“AD/CVD” means antidumping and countervailing duties. Antidumping duties may apply when a foreign producer or exporter sells merchandise in the United States at less than normal value. Countervailing duties may apply when a foreign government provides countervailable subsidies. These measures typically affect importers of covered merchandise from specified countries, and the importer may be responsible for entry requirements and payment of additional duties. Scope interpretation and final liability can require review by Customs and Border Protection, the relevant trade agencies, or a customs professional.

What to check

• Read the measure’s official scope language and compare it with the product’s composition, manufacturing process, physical form, and intended use.
• Confirm the product’s HTSUS classification, but do not treat the tariff number as a substitute for the scope analysis.
• Identify the country of production and the producer or exporter; AD/CVD coverage often depends on these details, not only the shipping origin.
• Check entry instructions, cash-deposit requirements, and whether any exclusions, certifications, or special documentation apply.
• Keep technical specifications, product data sheets, invoices, and origin records, and ask a customs broker or trade counsel to review uncertain cases.
