Analysis
Subheading 7226.91 covers not further worked than hot-rolled, within heading 7226. The first six digits are shared by every country that uses the Harmonized System, so this part of the code is the same in the US, UK and EU schedules; the 6 US tariff lines below it are national.
Every one of its 6 tariff lines is duty-free at the general rate, so classification within the subheading affects statistics and Chapter 99 measures rather than the base duty.
The US splits it as follows: 7226.91.05 for of chipper knife steel (duty-free), 7226.91.15 for of a width of 300 mm or more (duty-free), 7226.91.25 for of a width of less than 300 mm (duty-free), 7226.91.50 for of a thickness of 4.75 mm or more (duty-free), 7226.91.70 for of a width of 300 mm or more (duty-free) and 7226.91.80 for of a width of less than 300 mm (duty-free).
By Census's concordance, most of its statistical lines are made by Iron and Steel Mills and Ferroalloy Manufacturing (331110). Those are the NAICS industries a US producer of these goods would report under.
