Analysis
Heading 2929 of the Harmonized Tariff Schedule covers compounds with other nitrogen function. It divides into 2 six-digit subheadings and 12 eight-digit tariff lines, with 18 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 2929.10.10 (toluenediisocyanates (unmixed)) and 2929.10.15 (mixtures of 2,4- and 2,6-toluenediisocyanates).
2 of its 12 lines with a percentage rate are duty-free at the general rate (17%) and 10 are dutiable, from duty-free up to 6.5%. The median line pays 6.5%.
Its median rate of 6.5% sits at the 83rd percentile of the headings in chapter 29.
The largest subheadings are 2929.10 (isocyanates, 8 lines) and 2929.90 (other, 4 lines).
By Census's concordance, most of its statistical lines are made by All Other Basic Organic Chemical Manufacturing (325199). Those are the NAICS industries a US producer of these goods would report under.
