Analysis
HTS 1209.91.40 covers vegetable seeds: onion under heading 1209 (seeds, fruits and spores of a kind used for sowing).
The normal trade relations rate here is zero, shared by about 77% of the 44 tariff lines in chapter 12, a useful check when a neighbouring dutiable line is a candidate. 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 111219 (Other Vegetable (except Potato) and Melon Farming). That concordance is how imports of this line are compared with US output.
All 5 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.
