Importing European stone to the US: HTS codes, duties and documents
What actually appears on the customs paperwork when a container of worked stone lands in the US — the HTS codes by stone type, and the documents that keep it moving.
Worked stone enters under Chapter 68, not Chapter 25
Raw, unworked blocks fall under Chapter 25, but the moment stone is sawn into slabs or cut to size it becomes 'worked monumental or building stone' under heading 6802. Getting this right on the commercial invoice avoids reclassification delays at entry.
The codes by stone type
Marble slab, worked: 6802.91.05. Travertine, honed slab: 6802.91.20. Limestone, worked: 6802.92. Granite, worked: 6802.93. Quartzite and other monumental stone: 6802.99. Naming the correct code per material on the invoice is the single biggest avoidable cause of customs friction.
The documents a clean entry needs
Commercial invoice with HTS line per material and country of origin; packing list with crate weights and dimensions; bill of lading; and, for solid-wood crates, an ISPM-15 heat-treatment stamp. Marking must show country of origin (19 USC 1304). Missing the ISPM-15 stamp is a common, expensive hold.
Why the code matters to a buyer
Duty rate, broker speed and landed cost all hang off the classification. A good source quotes you the HTS per material up front rather than leaving it to the broker — which is why every material page here carries its US import code.
