Sulfanilic Acid — China — A-570-815

A measure labeled “Sulfanilic Acid” with type “AD/CVD” concerns a trade-remedy action involving a specified chemical product. AD means antidumping: it addresses imports that the government determines are sold in the United States at less than fair value. CVD means countervailing duty: it addresses imports that benefit from certain foreign-government subsidies. These are additional trade-remedy duties, separate from ordinary customs duty and fees.

The measure typically affects US importers of the covered product from the countries and producers or exporters identified in the official measure. Coverage depends on the legal product description and scope, not just the product name or a tariff classification. An importer should verify the product’s chemical characteristics, form, use, origin, manufacturer, and exporter. Misclassification or failure to report an applicable AD/CVD requirement can lead to additional liability, so a customs broker or trade-remedy specialist may be appropriate.

What to check

• Read the official scope language and compare it with the product’s composition, physical form, packaging, and intended use; do not rely on the name alone.
• Confirm the product’s HTSUS classification, country of origin, manufacturer, and exporter, and check whether the measure distinguishes among companies or countries.
• Determine whether the entry requires an AD/CVD case identifier, cash-deposit instruction, or other filing information in the current official customs guidance.
• Check whether exclusions, product-specific thresholds, or scope rulings could apply, and keep technical records supporting that conclusion.
• Ask a customs broker or trade-remedy attorney to review uncertain scope or origin questions before entry, and monitor official agency updates for changes.
