Analysis
Subheading 6902.90 covers other, within heading 6902. 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.
Every one of its 2 tariff lines is duty-free at the general rate, so classification within the subheading affects statistics and Chapter 99 measures rather than the base duty.
The US splits it as follows: 6902.90.10 for other: bricks (duty-free) and 6902.90.50 for other: other (duty-free).
By Census's concordance, most of its statistical lines are made by Clay Building Material and Refractories Manufacturing (327120). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 6902.90 once they fall within heading 6902 (refractory bricks, blocks, tiles and similar refractory ceramic constructional 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.
