Analysis
Subheading 7306.90 covers other, within heading 7306. 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 2 US tariff lines below it are national.
Every one of its 2 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: 7306.90.10 for of iron or nonalloy steel (duty-free) and 7306.90.50 for other: of alloy steel (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.
Goods only reach 7306.90 once they fall within heading 7306 (other tubes, pipes and hollow profiles (for example, open seamed or welded, riveted or…). Under General Rule 6, subheadings are then compared only with others at the same level, so a product is matched against its siblings, not against lines elsewhere in the chapter.
