6904
Ceramic building bricks, flooring blocks, support or filler tiles and the like
Analysis
Heading 6904 of the Harmonized Tariff Schedule covers ceramic building bricks, flooring blocks, support or filler tiles and the like. It divides into 2 six-digit subheadings and 2 eight-digit tariff lines, with 5 ten-digit statistical suffixes below them.
Every one of its 2 tariff lines is duty-free at the general rate, so classification within the heading affects statistics and Chapter 99 measures rather than the base duty.
Its median rate of duty-free sits at the 13th percentile of the headings in chapter 69.
The largest subheadings are 6904.10 (unnamed, 1 line) and 6904.90 (unnamed, 1 line).
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.
The heading text decides whether a product belongs here at all (General Rule of Interpretation 1); the subheadings and lines below it only apply once that is settled. Section and chapter notes can override the heading wording, so read them for borderline goods.
