Rough or merely split stone is generally classified in HTS Chapter 25 as a mineral product, while stone that has been sawn, shaped, dressed, or otherwise worked falls under Chapter 68. The degree of processing — not just the stone variety — determines which heading applies, and misclassification between these chapters is a common audit finding.
Yes. Quartz surface products and certain marble and granite articles have been subject to antidumping duty orders from specific countries. Importers should verify the current scope of active orders with the US Department of Commerce, as scope rulings can extend to products that may not appear covered on their face.
