Scope text

Legally operative description of covered merchandise from the Federal Register

Quartz surface products consist of slabs and other surfaces created from a mixture of materials that includes predominately silica (e.g., quartz, quartz powder, cristobalite, glass powder) as well as a resin binder (e.g., an unsaturated polyester). The incorporation of other materials, including, but not limited to, pigments, cement, or other additives does not remove the merchandise from the scope of the orders. However, the scope of the orders only includes products where the silica content is greater than any other single material, by actual weight. Quartz surface products are typically sold as rectangular slabs with a total surface area of approximately 45 to 60 square feet and a nominal thickness of one, two, or three centimeters. However, the scope of these orders includes surface products of all other sizes, thicknesses, and shapes. In addition to slabs, the scope of these orders includes, but is not limited to, other surfaces such as countertops, backsplashes, vanity tops, bar tops, work tops, tabletops, flooring, wall facing, shower surrounds, fire place surrounds, mantels, and tiles. Certain quartz surface products are covered by the orders whether polished or unpolished, cut or uncut, fabricated or not fabricated, cured or uncured, edged or not edged, finished or unfinished, thermoformed or not thermoformed, packaged or unpackaged, and regardless of the type of surface finish. In addition, quartz surface products are covered by the orders whether or not they are imported attached to, or in conjunction with, non-subject merchandise such as sinks, sink bowls, vanities, cabinets, and furniture. If quartz surface products are imported attached to, or in conjunction with, such non-subject merchandise, only the quartz surface product is covered by the scope. Subject merchandise includes material matching the above description that has been finished, packaged, or otherwise fabricated in a third country, including by cutting, polishing, curing, edging, thermoforming, attaching to, or packaging with another product, or any other finishing, packaging, or fabrication that would not otherwise remove the merchandise from the scope of the orders if performed in the country of manufacture of the quartz surface products. The scope of the orders does not cover quarried stone surface products, such as granite, marble, soapstone, or quartzite. Specifically excluded from the scope of the orders are crushed glass surface products. Crushed glass surface products must meet each of the following criteria to qualify for this exclusion: (1) The crushed glass content is greater than any other single material, by actual weight; (2) there are pieces of crushed glass visible across the surface of the product; (3) at least some of the individual pieces of crushed glass that are visible across the surface are larger than 1 centimeter wide as measured at their widest cross-section (``Glass Pieces''); and (4) the distance between any single Glass Piece and the closest separate Glass Piece does not exceed three inches.

Frequently asked questions

What is AD/CVD case C-489-838?

C-489-838 is a U.S. countervailing duty (CVD) order on quartz surface products from Türkiye, issued by the U.S. Department of Commerce. It is part of the trade-remedy regime that levies cash deposits at entry on imports found to be sold below fair value (AD) or to benefit from foreign government subsidies (CVD).

What is the deposit rate for C-489-838?

The country-wide cash deposit rate for C-489-838 is 2.43%. This rate applies to importers of non-listed manufacturers/exporters from Türkiye. Individual exporters and producers may have lower (or higher) case-specific rates from Commerce administrative reviews — see the manufacturer rates linked from this page where available.

When did C-489-838 take effect, and is it still active?

C-489-838 took effect on January 15, 2026 and is currently in active status — cash deposits apply at entry on every shipment in scope.

How do I check if my shipment falls within the scope of C-489-838?

Two factors determine scope: (1) the product's HTS code(s) and physical characteristics — covered codes are listed on this page (12 flagged); and (2) the product's country of origin — this order applies to imports from Türkiye. The order's scope text — also on this page — is the legally binding description. When borderline cases arise, importers can request a formal scope ruling from Commerce. Tandom's lookup tool matches your HTS + origin against every active order in seconds.

What HTS codes are covered by C-489-838?

C-489-838 flags 12 HTS codes in Tandom's catalog. The full list is shown on this page. HTS coverage alone does not guarantee scope — physical-characteristic exclusions in the scope text may carve out specific products.

Where is the official Federal Register notice for C-489-838?

The official Federal Register citation for C-489-838 is 2020-13374. The link is on this page; clicking it opens the canonical FR document on federalregister.gov, which carries the legally operative text — scope, rates, exclusions, and effective dates.

What is the companion case for C-489-838?

C-489-838 has a companion case at A-489-837. AD orders frequently run alongside a CVD order on the same product/country (or vice versa). Both deposits stack on top of base duties — importers pay the full sum of both rates at entry where both orders apply.
