ITA AD/CVD · Expired · TW

Plain-language explainer

Written to help non-specialists understand this page. Rates, dates, and legal facts come from the official records above and on the linked source.

A measure titled “Helical Spring Lock Washers” under AD/CVD concerns imported products that may fall within the scope of an antidumping (AD) or countervailing duty (CVD) order. AD duties address imports sold at less than normal value, while CVD duties address benefits that a foreign government provides to producers or exporters. These are trade-remedy duties and are separate from ordinary customs duty, merchandise processing fees, and other import charges.

The measure typically affects importers bringing covered washers from the countries and producers or exporters identified in the official order. A product’s tariff classification, such as its Harmonized Tariff Schedule (HTSUS) number, can help identify possible coverage, but the written scope description controls. If the merchandise is covered, the importer may need to provide an AD/CVD cash deposit and could later face additional duty liability. Confirming coverage may require a customs broker, trade attorney, or a formal scope ruling from the relevant authority.
