6815

Analysis

Heading 6815 of the Harmonized Tariff Schedule covers articles of stone or of other mineral substances (including carbon fibers, articles of carbon fibers and articles of peat), not elsewhere specified or included. It divides into 7 six-digit subheadings and 8 eight-digit tariff lines, with 10 ten-digit statistical suffixes below them.

Every one of its 8 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.

The largest subheadings are 6815.99 (other, 2 lines), 6815.11 (unnamed, 1 line), 6815.12 (unnamed, 1 line) and 6815.13 (unnamed, 1 line).

Its median rate of duty-free sits at the 30th percentile of the headings in chapter 68.

By Census's concordance, most of its statistical lines are made by Carbon and Graphite Product Manufacturing (335991), All Other Miscellaneous Nonmetallic Mineral Product Manufacturing (327999) and Clay Building Material and Refractories Manufacturing (327120). Those are the NAICS industries a US producer of these goods would report under.
