Analysis
Heading 2801 of the Harmonized Tariff Schedule covers fluorine, chlorine, bromine and iodine. It divides into 3 six-digit subheadings and 4 eight-digit tariff lines, with 4 ten-digit statistical suffixes below them.
2 of its 4 lines with a percentage rate are duty-free at the general rate (50%) and 2 are dutiable, from duty-free up to 5.5%. The median line pays 1.85%.
The spread of 5.5 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 5.5%, applies to 2801.30.20 (fluorine; bromine: bromine).
The largest subheadings are 2801.30 (fluorine; bromine, 2 lines), 2801.10 (unnamed, 1 line) and 2801.20 (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.
Its median rate of 1.85% sits at the 40th percentile of the headings in chapter 28.
