Reaction initiators, reaction accelerators and catalytic preparations, not elsewhere specified or included
Analysis
Heading 3815 of the Harmonized Tariff Schedule covers reaction initiators, reaction accelerators and catalytic preparations, not elsewhere specified or included. It divides into 4 six-digit subheadings and 7 eight-digit tariff lines, with 8 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 3815.90.10 (of bismuth, of tungsten or of vanadium).
4 of its 7 lines with a percentage rate are duty-free at the general rate (57%) and 3 are dutiable, from duty-free up to 6.5%. The median line pays duty-free.
Its median rate of duty-free sits at the 12th percentile of the headings in chapter 38.
The largest subheadings are 3815.90 (other, 4 lines), 3815.11 (unnamed, 1 line), 3815.12 (unnamed, 1 line) and 3815.19 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by Other Basic Inorganic Chemical Manufacturing (325180). Those are the NAICS industries a US producer of these goods would report under.
