Other Articles of Cement, Concrete, or Artificial Stone, NESOI (Including Agglomerated Quartz Slabs)

Line 6810990020 applies to rectangular agglomerated quartz slabs measuring 3 meters or more in length and 1.25 meters or more in width — dimensions associated with jumbo-format slabs used in fabrication shops. Line 6810990040 covers countertop-grade slabs that do not meet those dimensional thresholds. Importers should document slab dimensions on the commercial invoice and packing list to support the correct 10-digit classification and avoid CBP examination.

Antidumping and countervailing duty orders on quartz surface products from China significantly increased the landed cost of Chinese-origin slabs, prompting US importers and distributors to shift sourcing to Vietnam, India, and other countries not covered by those orders. Importers should verify that current orders do not extend to their specific supplier country and product specification, as scope rulings and circumvention investigations can affect non-Chinese origins as well. Consulting a licensed customs broker before establishing a new supply relationship is strongly advisable.
