Analysis
Subheading 7228.30 covers of tool steel (other than high-speed steel), within heading 7228. 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: 7228.30.20 for of ball-bearing steel (duty-free), 7228.30.40 for of chipper knife steel, not cold-formed (duty-free), 7228.30.60 for of tool steel (other than high-speed steel): other (duty-free) and 7228.30.80 for other bars and rods, not further worked than hot-rolled, hot-drawn or… (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.
