8431
Parts suitable for use solely or principally with the machinery of headings 8425 to 8430
Analysis
Heading 8431 of the Harmonized Tariff Schedule covers parts suitable for use solely or principally with the machinery of headings 8425 to 8430. It divides into 8 six-digit subheadings and 10 eight-digit tariff lines, with 44 ten-digit statistical suffixes below them.
Every one of its 10 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 8431.43 (parts for boring or sinking machinery of…, 2 lines), 8431.49 (other, 2 lines), 8431.10 (unnamed, 1 line) and 8431.20 (unnamed, 1 line).
Its median rate of duty-free sits at the 30th percentile of the headings in chapter 84.
By Census's concordance, most of its statistical lines are made by Construction Machinery Manufacturing (333120), Oil and Gas Field Machinery and Equipment Manufacturing (333132) and Overhead Traveling Crane, Hoist, and Monorail System Manufacturing (333923). Those are the NAICS industries a US producer of these goods would report under.
