U.S. Antidumping and Countervailing Duties on Certain Quartz Surface Products from China (A-570-084 / C-570-085)

This is an educational summary — NOT a scope determination or filing advice. It does not decide whether your specific goods are covered. Always verify against the latest U.S. Commerce and CBP instructions.

Certain quartz surface products from China may be subject to both a U.S. antidumping order (A-570-084) and a countervailing duty order (C-570-085).

Effective/entry-specific deposit and liquidation treatment depends on Commerce and CBP instructions, not only the publication date.

Certain quartz surface products from China are covered by two U.S. Department of Commerce trade-remedy orders: an antidumping (AD) order under case A-570-084 and a countervailing duty (CVD) order under case C-570-085. Importers of engineered quartz slabs, countertops, and similar products of Chinese origin should carefully review whether their goods may fall within the written scope.

Scope — simplified screening examples, not full legal scope

The official written scope controls. The examples below are screening references only.

Products that may be covered (examples)

•May include engineered/artificial quartz slabs made primarily of crushed quartz bound with a resin binder
•May include finished quartz countertops cut and polished to size
•May include quartz vanity tops and tabletops
•May include quartz surface products whether polished, unpolished, or otherwise finished
•May include quartz surface products regardless of edge treatment, thickness, or color
•May include quartz surface products further processed or fabricated in a third country from Chinese-origin quartz slabs (subject to Commerce determination)

Products that may require separate review or may fall outside this order

?May exclude products made from crushed glass rather than crushed quartz (verify against scope)
?May exclude solid surface products made primarily of acrylic or polyester resins without quartz
?May exclude natural stone slabs such as granite or marble
?May exclude ceramic or porcelain tile products
?May exclude concrete or cementitious surface products

Scope control: The listed HTS codes are screening references only; Commerce's written scope language controls whether a product is covered, and parts, unfinished, or fabricated quartz surface products may still fall within scope depending on that language.

Who it affects

This typically matters for importers of engineered/artificial quartz slabs, countertops, vanity tops, and similar quartz surface products manufactured in or exported from China, including goods fabricated or finished in third countries from Chinese-origin material.

What the duty means

Covered goods generally require a cash deposit at entry; because both an AD (A-570-084) and a CVD (C-570-085) order exist, both types of deposits may apply. Rates vary by exporter/producer combination and by administrative review and can be substantial. A 0% cash-deposit rate is NOT an exemption — the order still applies and the entry must be declared as subject merchandise.

Importer checklist — how to assess your risk

☐Gather the commercial invoice and confirm the exact product description matches the goods.
☐Collect product photos, spec sheets, and slab dimensions/thickness for screening.
☐Document material composition, especially the percentage of crushed quartz versus resin or other binders.
☐Identify the intended use (countertops, vanities, tabletops, etc.).
☐Obtain and retain country-of-origin support, including manufacturing and any third-country processing details.
☐Record the full manufacturer, producer, and exporter names and confirm the specific producer/exporter combination.
☐Verify HTS classification against the listed reference codes (e.g., 6810990020, 6810990040, 681099, 250620, 6802).
☐Confirm scope questions with a licensed customs broker or trade counsel rather than relying only on supplier statements.
☐Verify the applicable cash-deposit rate against current Commerce review results and CBP AD/CVD messages before filing.

Risks to watch

⚠Circumvention or transshipment findings where Chinese quartz is processed or finished in a third country to disguise origin.
⚠Scope inquiries that could bring borderline products within the orders.
⚠Using the wrong exporter/producer combination, which can trigger a higher all-others or China-wide rate.
⚠Misdeclaration or failure to declare subject merchandise, which can lead to penalties and retroactive duty assessments.

The same category of quartz surface products may be subject to trade-remedy orders from multiple countries, so each origin should be independently reviewed against the applicable orders.

FAQ

Is there antidumping duty on quartz surface products from China?

There is an antidumping order under case A-570-084 and a separate countervailing duty order under case C-570-085 covering certain quartz surface products from China; whether specific goods are covered depends on Commerce's written scope, so importers should verify.

Does a 0% deposit rate mean no duty?

No. A 0% cash-deposit rate is not an exemption — the orders still apply, the merchandise must be declared as subject, and rates can change through administrative reviews.

Are parts or unassembled quartz surface products covered?

They may still be covered depending on Commerce's written scope; unfinished, fabricated, or further-processed quartz surface products can fall within scope, so importers should confirm with a licensed broker or counsel.

Possible risk

Risk signal: Higher concern if the goods are engineered/artificial quartz slabs or countertops of Chinese origin; a separate review is needed for glass-based products, non-quartz solid surfaces, parts, and third-country fabrication or processing.

Bottom line: Certain quartz surface products from China may be covered by A-570-084 (AD) and C-570-085 (CVD); confirm scope, origin, exporter/producer identity, and current deposit rates before entry.

Not a scope determination or filing advice — confirm coverage and current deposit rates with a licensed customs broker and the latest Commerce/CBP instructions before entry.
