What is the anti-dumping duty (ADD)?
These duties are imposed on goods whose price on the imported goods is below the fair value in the national market. The main reason countries impose this is to avoid undercutting the businesses in the federal government and, overall, the local economy.
The fair market value can be determined based on the product’s cost, domestic price, and profit.
It is not a rule that anti-dumping duties are applied to all products. Whether or not the imported product will have this tariff depends on the type of product and country of origin.
You can find more details for specific countries on the International Trade Administration’s website.
