Anti-dumping duties are additional import duties applied when a government determines that foreign goods are being sold into its market at unfairly low prices. These duties are meant to offset dumping and protect domestic industries from injury caused by underpriced imports. In customs compliance, anti-dumping duties may apply to specific products, countries, manufacturers, or exporters and are usually charged in addition to normal customs duties. Importers must check AD orders carefully because rates, scope, and supplier-specific rules can change.
Anti-dumping duties (ADD) are tariffs imposed on foreign goods sold below their normal market value in the exporter’s home country. The U.S. Department of Commerce administers anti-dumping orders following petitions from domestic industries.
Impact on Importers
- Duty deposits required at entry based on an estimated rate
- Annual reviews can adjust rates retroactively
- ADD orders are product and country specific; verify applicability before placing orders
