Sulfanilic Acid — Hungary — A-437-804

“Sulfanilic Acid” identifies the product covered by a US trade measure, while “AD/CVD” means antidumping and countervailing duties. Antidumping duties (AD) address imports sold in the United States at less than normal value; countervailing duties (CVD) address benefits or subsidies provided by a foreign government. These duties are separate from ordinary customs duty and may apply in addition to it.

The measure typically affects US importers, manufacturers, distributors, and other parties bringing potentially covered sulfanilic acid into the United States from specified countries or exporters. Coverage depends on the product’s legal description, country of origin, exporter or producer, and applicable scope information—not only the product name or tariff classification. An importer may be responsible for declaring the measure and paying duties, and should understand that Customs and Border Protection (CBP) can require additional documentation or a duty deposit.

What to check

• Read the measure’s scope description carefully, including chemical characteristics, forms, uses, and stated exclusions; do not rely on the product name alone.
• Confirm the product’s Harmonized Tariff Schedule (HTS) classification, country of origin, producer, and exporter, because these facts can determine whether the measure applies.
• Check the official AD/CVD instructions and current CBP entry requirements for the applicable case and review whether a cash-deposit or other special entry requirement is involved.
• Keep purchase orders, invoices, production records, origin documents, technical specifications, and subsidy or exporter information that support the entry declaration.
• Ask a qualified customs broker or trade counsel to review uncertain scope questions, especially where the product is a blend, derivative, intermediate, or potentially excluded item.
