Alkyl Phosphate Esters — China — A-570-168

“Alkyl Phosphate Esters” is a trade-remedy measure involving chemical products that may be covered by the defined product scope. AD means antidumping: the government investigates whether imported goods are sold in the United States at less than fair value. CVD means countervailing duty: the government investigates whether foreign producers or exporters benefited from government subsidies. The two remedies can apply separately or together.

The measure typically affects importers, foreign exporters, and producers of the covered merchandise from specified countries. It matters because an importer may owe additional duties, often collected through customs entry procedures as cash deposits, and may face later duty assessments. Product coverage depends on the written scope—not just the product name or tariff classification—so a chemical’s ingredients, formulation, physical form, and intended use may need review. A customs broker or trade-remedy specialist may be needed for difficult scope questions.

What to check

• Read the official scope language and compare it with the product’s composition, formulation, physical form, and packaging; do not rely on the product name alone.
• Confirm the country of origin and identify the actual manufacturer, producer, and exporter, because AD/CVD treatment can depend on these parties and the country involved.
• Check the applicable Harmonized Tariff Schedule classification, while remembering that classification is an identification tool and does not by itself determine scope.
• Ask your customs broker to verify the required entry documentation, cash-deposit treatment, and any importer certification or reporting obligations.
• Request a formal scope review or qualified trade-remedy advice if the product is similar to the covered merchandise but may fall outside the written definition.
