Analysis
Subheading 7211.23 covers containing by weight less than 0.25 percent of carbon, within heading 7211. 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 5 US tariff lines below it are national.
Every one of its 5 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: 7211.23.15 for of high-strength steel (duty-free), 7211.23.20 for of a thickness exceeding 1.25 mm: other (duty-free), 7211.23.30 for of a thickness exceeding 0.25 mm but not exceeding 1.25 mm (duty-free), 7211.23.45 for of a thickness not exceeding 0.25 mm (duty-free) and 7211.23.60 for containing by weight less than 0.25 percent of carbon: 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.
