Importers of Monumental & Building Stone (Except Slate) — Molded, Polished or Otherwise Worked paid $21.6M in duties in August 2026, an average duty rate of 18.34% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataGranite countertops, carved limestone architectural elements, polished basalt pavers, and similar value-added articles of building or monumental stone (excluding slate, marble, travertine, and alabaster) are captured here — the finished-goods counterpart to the simply-cut heading 66135. The degree of processing — polishing, carving, molding, or decorating — is the key classification trigger separating this heading from its simply-cut equivalent. Granite dominates US import volumes in this category, with China a major supplier of fabricated granite products. Importers should be aware that certain fabricated stone articles may be subject to antidumping or countervailing duty orders depending on origin and product form.

Yes. Certain fabricated granite articles from China have been subject to antidumping and countervailing duty proceedings. Importers should check the current scope of any active orders with CBP or the Department of Commerce before shipment, as scope language can be product-specific and scope rulings may be required for borderline articles.
Cutting alone — even to precise final dimensions — is generally 'simply cut' if the surface remains in a raw sawn state. Once any polishing, honing, edge profiling (bullnose, beveled, ogee), carving, or surface decoration is applied, the article is 'worked.' For granite countertops, the edge profile and surface finish are typically the decisive factors, and both should be described on the commercial invoice.
