Analysis
Heading 2930 of the Harmonized Tariff Schedule covers organo-sulfur compounds. It divides into 8 six-digit subheadings and 22 eight-digit tariff lines, with 40 ten-digit statistical suffixes below them.
The spread of 6.5 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 6.5%, applies to 2930.20.10 (aromatic: pesticides) and 2930.20.20 (aromatic: other).
7 of its 22 lines with a percentage rate are duty-free at the general rate (32%) and 15 are dutiable, from duty-free up to 6.5%. The median line pays 3.7%.
The largest subheadings are 2930.90 (other, 11 lines), 2930.20 (thiocarbamates and dithiocarbamates, 4 lines), 2930.30 (thiuram mono-, di- or tetrasulfides, 2 lines) and 2930.10 (unnamed, 1 line).
Its median rate of 3.7% sits at the 34th percentile of the headings in chapter 29.
By Census's concordance, most of its statistical lines are made by All Other Basic Organic Chemical Manufacturing (325199) and Medicinal and Botanical Manufacturing (325411). Those are the NAICS industries a US producer of these goods would report under.
