7308

Analysis

Heading 7308 of the Harmonized Tariff Schedule covers structures (excluding prefabricated buildings of heading 9406) and parts of structures (for example, bridges and bridge sections, lock gates, towers, lattice masts, roofs, roofing frameworks, doors and windows and their…. It divides into 5 six-digit subheadings and 9 eight-digit tariff lines, with 15 ten-digit statistical suffixes below them.

Every one of its 9 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 7308.90 (other, 4 lines), 7308.30 (doors, windows and their frames and thresholds…, 2 lines), 7308.10 (unnamed, 1 line) and 7308.20 (unnamed, 1 line).

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 Fabricated Structural Metal Manufacturing (332312), Metal Window and Door Manufacturing (332321) and Ornamental and Architectural Metal Work Manufacturing (332323). Those are the NAICS industries a US producer of these goods would report under.
