Analysis
Subheading 6802.21 covers marble, travertine and alabaster, within heading 6802. 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 2 US tariff lines below it are national.
None of its 2 lines is duty-free at the general rate. Rates run from 1.9% to 4.2% with a median of 3.05%, so the line you choose sets the duty.
The US splits it as follows: 6802.21.10 for marble, travertine and alabaster: travertine (4.2%) and 6802.21.50 for marble, travertine and alabaster: other (1.9%).
By Census's concordance, most of its statistical lines are made by Cut Stone and Stone Product Manufacturing (327991). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 6802.21 once they fall within heading 6802 (worked monumental or building stone (except slate) and articles thereof, other than goods…). Under General Rule 6, subheadings are then compared only with others at the same level, so a product is matched against its siblings, not against lines elsewhere in the chapter.
