ITA AD/CVD · Final action · CN

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.

An AD/CVD measure is a trade remedy. AD means antidumping: it addresses imports that a government determines are sold in the United States at less than fair value. CVD means countervailing duty: it addresses imports that benefit from certain government subsidies. These measures are separate from ordinary customs duty and may apply in addition to it.

This measure concerns certain large-diameter welded carbon and alloy steel line and structural pipe. It typically affects importers, manufacturers, exporters, and related parties handling covered pipe from specified countries or producers. Whether a shipment is covered depends mainly on the measure’s legal scope—such as product characteristics, dimensions, uses, exclusions, and origin—not merely on the product’s commercial name or HTS classification. If covered, the importer of record may have to provide additional cash deposits and could face later duty assessment based on official proceedings.
