Analysis
Subheading 6810.19 covers other, within heading 6810. The first six digits are shared by every country that uses the Harmonized System, so this part of the code is the same in the US, UK and EU schedules; the 3 US tariff lines below it are national.
None of its 3 lines is duty-free at the general rate. Rates run from 3.9% to 9% with a median of 4.9%, so the line you choose sets the duty.
The spread of 5.1 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 9%, applies to 6810.19.14 (floor and wall tiles: other).
The US splits it as follows: 6810.19.12 for of stone agglomerated with binders other than cement (4.9%), 6810.19.14 for floor and wall tiles: other (9%) and 6810.19.50 for other: other (3.9%).
By Census's concordance, most of its statistical lines are made by Other Concrete Product Manufacturing (327390). Those are the NAICS industries a US producer of these goods would report under.
