ANNEX
A. Effective with respect to goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a. m. eastern time on August 15, 2026, subchapter III of chapter 99 of the Harmonized Tariff Schedule of the United States( HTSUS) is hereby modified as follows:
1. by inserting in numerical sequence the following new U. S. note 41 and provisions:
“ 41.( a) Headings 9903.45.30 and 9903.45.31 establish temporary modifications applicable to entries of quartz surface products. For the purposes of this note, the term quartz surface products(“ QSP”) means 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 this note. However, the scope only includes products where the silica content is greater than any other single material, by actual weight. QSP is 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 includes surface products of all other sizes, thicknesses, and shapes. In addition to slabs, the scope includes, but is not limited to, other surfaces such as countertops, backsplashes, vanity tops, bar tops, work tops, tabletops, flooring, wall facing, shower surrounds, fireplace surrounds, mantels, and tiles. QSP may be 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 may have any type of surface finish. In addition, QSP is covered by the scope whether or not it is imported attached to, or in conjunction with, non-subject merchandise such as sinks, sink bowls, vanities, cabinets, and furniture. If QSP is imported attached to, or in conjunction with, such non-subject merchandise, only the QSP 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 if performed in the country of manufacture of the QSP. The scope does not cover quarried stone surface products, such as granite, marble, soapstone or quartzite.
The scope covers imported products provided for under HTSUS subheadings 6810.99.0020, 6810.99.0040, and 7020.00.6000.
( b) Imported goods provided for under headings 9903.45.30 and 9903.45.31 shall be subject to duties as provided herein, and such duties shall be cumulative and imposed in addition to the rate of duty established for any such goods in chapters 68 or 70 of the tariff schedule. All antidumping,
