Analysis
HTS 8433.20.00 covers harvesting or threshing machinery, including straw or fodder balers; grass or hay mowers; machines for cleaning, sorting or grading eggs, fruit or other… under heading 8433 (harvesting or threshing machinery, including straw or fodder balers; grass or hay mowers…). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in number of items.
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 333111 (Farm Machinery and Equipment Manufacturing), an industry of 1,120 US establishments employing 69,047 people. That is the industry code a US manufacturer of the same product would normally use.
All 11 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
