Quartz surface products from China: A‑570‑084 / C‑570‑085 duty rates

Exporter and separate rates

A company rate applies only when the exporter on your commercial invoice is that company, under the name printed in the notice. Every other Chinese exporter pays the China-wide AD rate and the all-others CVD rate.

"Period" is the period of review the rate came from; "Investigation" means the rate was set when the order was issued. "Margin" is the dumping margin before the export-subsidy offset; CVD rates have no margin.

What the order covers

What makes it quartz

Slabs and other surfaces made from a mixture that is mostly silica (quartz, quartz powder, cristobalite) with a resin binder such as unsaturated polyester. Silica must outweigh every other single material by actual weight. Adding pigments, cement or other additives does not take a product out.

Any size or shape

Typical slabs are about 45 to 60 square feet at 1, 2 or 3 cm, but every other size, thickness and shape is covered too.

Any stage of finishing

Covered whether polished or not, cut or uncut, fabricated or not, cured or uncured, edged or not, finished or unfinished, thermoformed or not, packaged or unpackaged, with any surface finish.

Attached to or shipped with other goods

Quartz is covered whether or not it is imported attached to, or together with, non-subject goods such as sinks, sink bowls, vanities, cabinets and furniture. In that case only the quartz is covered: the AD/CVD deposit applies to the quartz, not to the cabinet or vanity it came on.

Finished in any third country

Quartz from China that is cut, polished, cured, edged, thermoformed, attached to or packed with another product, or otherwise finished, packaged or fabricated in any third country stays in scope, as long as the same work done in China would not have taken it out.

Other trade names

Also sold as engineered, artificial, agglomerated, synthetic, processed or manufactured stone or quartz, and Bretonstone.

Traps buyers hit

• Chinese slab cut or polished in Malaysia stays Chinese and stays in scope (scope ruling, 87 FR 64009). In the last completed review, Malaysian exporters that could not prove a non-Chinese slab were held to the China-wide rate (89 FR 92622).
• An exporter outside China that has no rate of its own pays the AD rate of the Chinese company that supplied it; if that Chinese supplier has no separate rate, the China-wide rate of 326.15% applies (86 FR 43520; 89 FR 92622).

How to confirm the rate before entry

1. 1. Search CBP's AD/CVD message database for A-570-084 and C-570-085. The newest cash-deposit message should carry the same rate and effective date as the notice above. If it shows a later date, a newer notice exists. We could not read the database from our tools, so this page cites no CBP message numbers; search it yourself or ask your broker for the current message number.
2. 2. Get the exporter's and producer's full legal names from the factory, as they will appear on the commercial invoice, and compare them with the rate table. A trading company has its own rate or none.
3. 3. Send your broker the questions below before the goods ship, with the product spec sheet.
4. 4. Budget for the final bill, not just the deposit (why).
