Persulfates — China — A-570-847

A trade measure titled “Persulfates” and identified as AD/CVD concerns possible special import duties on covered persulfate products. AD means antidumping: the government may determine that imported goods are sold in the United States below their normal value. CVD means countervailing duty: the government may determine that imported goods benefit from foreign-government subsidies. These duties are separate from ordinary customs duty and may apply in addition to it.

The measure typically affects importers, manufacturers, distributors, and other parties bringing covered persulfates from specified countries or producers into the United States. Coverage depends on the legal product description, country of origin, producer or exporter, and the applicable tariff classification, often called the HTSUS subheading. An HTSUS code is a useful starting point, but it does not by itself decide whether merchandise is covered; the official scope of the proceeding controls. Importers may also face entry documentation, cash-deposit, and final-liability issues, so a customs broker or trade specialist should review uncertain cases.

What to check

• Read the official scope language and compare the product’s chemical composition, form, packaging, and intended use—not just its commercial name.
• Confirm the product’s country of origin, manufacturer, and exporter; AD/CVD coverage can vary by country and company.
• Check the relevant HTSUS classification, but treat it as an identification aid rather than the final coverage test.
• Ask your customs broker or trade counsel how the measure affects entry documentation, cash deposits, and possible retrospective assessment of final duties.
• Keep technical specifications, invoices, origin records, and supplier statements that support your coverage and classification analysis.
