Quartz Surface Products — China — C-570-085

A US trade measure covering “Quartz Surface Products” under AD/CVD addresses imported goods that may be subject to antidumping (AD) or countervailing duties (CVD). AD duties generally respond to imports sold at less than fair value, while CVD duties address benefits a foreign government may provide to producers or exporters. These duties are separate from ordinary customs duty and may apply in addition to it.

The measure typically affects importers, foreign manufacturers, exporters, and US purchasers of covered quartz-based surface materials. Coverage depends on the product’s technical characteristics and the legal product description, not simply its marketing name, invoice wording, or intended use. An importer should compare the goods with the measure’s scope and verify the correct Harmonized Tariff Schedule (HTSUS) classification, country of origin, manufacturer or exporter, and any applicable cash-deposit or entry requirements. Scope or classification questions may require a customs broker, trade attorney, or a formal ruling from the relevant US agency.

What to check

• Read the measure’s scope language and compare the product’s composition, dimensions, form, and intended use; do not rely only on the product name.
• Confirm the HTSUS classification, country of origin, manufacturer, and exporter, because these facts can affect whether and how the measure applies.
• Check current official instructions for AD/CVD cash deposits, entry documentation, exclusions, and certification requirements before importing.
• Ask the supplier for complete production and shipment details, including manufacturer identity and any changes in sourcing or processing.
• If the product is close to the scope boundary, request qualified customs or trade counsel review and consider whether a formal scope or classification ruling is appropriate.
