Analysis
HTS 9105.99.30 covers having no jewels or only one jewel under heading 9105 (other clocks).
The normal trade relations rate here is zero, shared by about 40% of the 48 tariff lines in chapter 91, a useful check when a neighbouring dutiable line is a candidate. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
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.
