7306

Analysis

Heading 7306 of the Harmonized Tariff Schedule covers other tubes, pipes and hollow profiles (for example, open seamed or welded, riveted or similarly closed), of iron or steel. It divides into 10 six-digit subheadings and 30 eight-digit tariff lines, with 68 ten-digit statistical suffixes below them.

Every one of its 30 tariff lines is duty-free at the general rate, so classification within the heading affects statistics and Chapter 99 measures rather than the base duty.

The largest subheadings are 7306.29 (other, 6 lines), 7306.61 (of square or rectangular cross section, 4 lines), 7306.69 (of other noncircular cross section, 4 lines) and 7306.21 (welded of stainless steel, 3 lines).

Its median rate of duty-free sits at the 38th percentile of the headings in chapter 73.

By Census's concordance, most of its statistical lines are made by Iron and Steel Mills and Ferroalloy Manufacturing (331110) and Iron and Steel Pipe and Tube Manufacturing from Purchased Steel (331210). Those are the NAICS industries a US producer of these goods would report under.
