2,4-Dichlorophenoxyacetic Acid — China — A-570-160

An AD/CVD measure is a U.S. trade remedy. “AD” means antidumping duty, which addresses imports sold at less than fair value; “CVD” means countervailing duty, which addresses certain government subsidies. A measure based on 2,4-Dichlorophenoxyacetic Acid generally concerns covered chemical products from specified countries, producers, exporters, or combinations of them—not automatically every product with a similar name.

The key professional term is the measure’s “scope,” which describes the covered merchandise by its physical characteristics, chemical composition, packaging, and sometimes its intended use. An importer may need to pay additional cash deposits at entry, in addition to ordinary customs duties, if the shipment falls within the scope. Classification under the HTSUS helps identify an entry, but the HTSUS number alone does not decide whether merchandise is covered; the official scope and applicable instructions control.

What to check

• Read the official scope language and compare it with the product’s chemical composition, concentration, form, packaging, and use.
• Confirm the country of origin and identify the actual manufacturer and exporter; AD/CVD treatment can vary by these details.
• Check the applicable AD/CVD case instructions and current Customs entry guidance before filing, rather than relying only on an HTSUS classification.
• Ask a customs broker or trade counsel to review ambiguous products and consider whether a formal scope ruling is appropriate.
• Keep technical specifications, safety data, invoices, origin records, and manufacturer information that support your scope and entry determination.
