Analysis
HTS 0802.42.00 covers chestnuts (Castanea spp.): shelled under heading 0802 (other nuts, fresh or dried, whether or not shelled or peeled).
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 47% of the 60 tariff lines in chapter 08. 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 111335 (Tree Nut Farming). That is the industry code a US manufacturer of the same product would normally use.
All 23 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.
