Analysis
Subheading 7225.40 covers other, not further worked than hot-rolled, not in coils, within heading 7225. 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 4 US tariff lines below it are national.
Every one of its 4 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: 7225.40.11 for of a thickness of 4.75 mm or more: of tool steel (duty-free), 7225.40.30 for of a thickness of 4.75 mm or more: other (duty-free), 7225.40.51 for of a thickness of less than 4.75 mm: of tool steel (duty-free) and 7225.40.70 for of a thickness of less than 4.75 mm: other (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.
