2511

Analysis

Heading 2511 of the Harmonized Tariff Schedule covers natural barium sulfate (barytes); natural barium carbonate (witherite), whether or not calcined, other than barium oxide of heading 2816. It divides into 2 six-digit subheadings and 3 eight-digit tariff lines, with 3 ten-digit statistical suffixes below them.

Every one of its 3 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.

1 of the lines carry specific or compound rates (per kilogram, per dozen and so on) rather than a percentage, so their burden depends on the unit value of the goods.

The largest subheadings are 2511.10 (natural barium sulfate (barytes), 2 lines) and 2511.20 (unnamed, 1 line).

By Census's concordance, most of its statistical lines are made by Other Nonmetallic Mineral Mining and Quarrying (21239) and Synthetic Dye and Pigment Manufacturing (325130). Those are the NAICS industries a US producer of these goods would report under.
