Sulfanilic Acid — India — A-533-806

A US trade measure for Sulfanilic Acid labeled AD/CVD concerns trade-remedy rules: antidumping (AD) and countervailing duty (CVD). AD may apply when imported merchandise is sold in the United States at less than its normal value, while CVD may apply when a foreign government provides a subsidy that benefits the merchandise. These duties are separate from ordinary customs duty and may be collected in addition to it.

The measure typically affects importers of the covered chemical, as well as foreign producers, exporters, and sometimes related products that meet the official scope description. The product name alone is not enough to decide coverage. An importer must compare the product’s composition, form, packaging, use, and other facts with the scope language, and review the applicable HTSUS classification. AD/CVD scope and HTSUS numbers are related but not interchangeable; scope controls whether the merchandise is covered, while classification helps with reporting and customs processing.

What to check

• Read the official scope description carefully, including chemical specifications, physical form, exclusions, and product uses.
• Confirm the correct HTSUS classification, but do not rely on the tariff number alone to determine whether the product is covered.
• Identify the actual manufacturer, producer, exporter, country of origin, and any related parties; AD/CVD treatment can depend on these facts.
• Check whether the shipment requires an AD/CVD entry message, cash deposit, bond, certification, or other filing through official CBP and Commerce guidance.
• Keep product specifications, supplier statements, invoices, and origin records, and ask a customs broker or trade-remedy specialist to review uncertain coverage.
