8431.39.00

Analysis

HTS 8431.39.00 covers of machinery of heading 8428: other under heading 8431 (parts suitable for use solely or principally with the machinery of headings 8425 to 8430). US Customs collects import statistics for it under 4 ten-digit suffixes, reported in number of items.

Goods from countries without normal trade relations pay the column 2 rate of 35% instead of nothing, so origin decides between free entry and a 35% duty.

Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 61% of the 823 tariff lines in chapter 84. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.

Census statistics map these goods to NAICS 333120 (Construction Machinery Manufacturing), an industry of 651 US establishments employing 64,700 people. That is the industry code a US manufacturer of the same product would normally use.

The ten-digit suffixes separate of elevators and conveyors, of oil and gas field machinery and of the woodland log handling equipment…. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.
