Corrosion Inhibitors — China — A-570-122

An AD/CVD measure concerning “Corrosion Inhibitors” is a trade-remedy action involving antidumping (AD) and/or countervailing duties (CVD). Antidumping duties address imports sold at less than fair value, while countervailing duties address benefits that a foreign government provides to producers or exporters. These duties are separate from ordinary customs duty and may apply in addition to it.

The measure typically affects importers bringing covered corrosion-inhibitor products from specified countries or producers. Coverage depends on the official product scope, which may describe the product’s ingredients, formulation, use, physical form, packaging, and exclusions. The Harmonized Tariff Schedule (HTS) classification can help identify potentially relevant entries, but it does not by itself decide whether merchandise is covered. If applicable, the importer may have additional entry, cash-deposit, recordkeeping, and liability obligations; a customs broker or trade-remedy professional may be needed for a scope determination.

What to check

• Read the official scope language and compare it with the product’s formulation, concentration, physical form, intended use, and packaging.
• Confirm the country of origin, manufacturer, exporter, and supplier chain; AD/CVD treatment can vary by origin and by named company or producer.
• Review the HTS classification, but do not rely on the tariff number alone; check whether the merchandise is expressly included or excluded by the scope.
• Ask your customs broker or trade-remedy counsel to verify coverage before entry, especially for mixtures, concentrates, or products with unusual specifications.
• Keep product specifications, ingredient records, invoices, origin documents, and scope-analysis support in case Customs or another authority requests substantiation.
