Chassis and Subassemblies Thereof — China — C-570-136

“Chassis and Subassemblies Thereof” describes a product scope covering certain chassis—supporting frames or structural assemblies used in vehicles or equipment—and specified parts or subassemblies of those chassis. The exact scope is controlled by the official measure text, not just the product title, and may include technical descriptions, exclusions, and tariff classification references.

“AD/CVD” means antidumping and countervailing duties. Antidumping duties (AD) address merchandise the government determines is sold in the United States at less than fair value. Countervailing duties (CVD) address merchandise that benefits from foreign-government subsidies. These measures typically affect importers of covered merchandise from the named countries, even when the importer is not accused of wrongdoing. The importer of record may be responsible for entry requirements, duty deposits, and later liability if final amounts differ.

What to check

• Read the official scope language and compare your product’s design, function, materials, and assembly level—not only its description or tariff code.
• Confirm the country of origin and export history, because AD/CVD coverage is generally tied to specified countries and can depend on production as well as shipment.
• Check the listed Harmonized Tariff Schedule (HTS) classifications, but treat them as screening tools; scope language controls when the code and product description do not align.
• Determine whether the product is a complete chassis, a covered subassembly, or an excluded component, and document the facts supporting that conclusion.
• Ask Customs and Border Protection or a qualified customs broker or trade lawyer about scope rulings, entry instructions, cash-deposit treatment, and potential importer liability when coverage is uncertain.
