7307
Tube or pipe fittings (for example, couplings, elbows, sleeves), of iron or steel
Analysis
Heading 7307 of the Harmonized Tariff Schedule covers tube or pipe fittings (for example, couplings, elbows, sleeves), of iron or steel. It divides into 10 six-digit subheadings and 20 eight-digit tariff lines, with 39 ten-digit statistical suffixes below them.
The spread of 6.2 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 6.2%, applies to 7307.19.90 (other: other) and 7307.22.50 (threaded elbows, bends and sleeves: other).
2 of its 20 lines with a percentage rate are duty-free at the general rate (10%) and 18 are dutiable, from duty-free up to 6.2%. The median line pays 4.9%.
Its median rate of 4.9% sits at the 90th percentile of the headings in chapter 73.
The largest subheadings are 7307.91 (flanges, 3 lines), 7307.93 (butt welding fittings, 3 lines), 7307.99 (other, 3 lines) and 7307.19 (other, 2 lines).
By Census's concordance, most of its statistical lines are made by Other Metal Valve and Pipe Fitting Manufacturing (332919) and Iron Foundries (331511). Those are the NAICS industries a US producer of these goods would report under.
