Analysis
HTS 8539.29.30 covers designed for a voltage not exceeding 100 V: other under heading 8539 (electrical filament or discharge lamps, including sealed beam lamp units and ultraviolet…). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in number of items.
Neighbouring lines carry rates from 2.6% to 5.8%, so the exact line matters. The widest gap is with 8539.29.10 (christmas-tree lamps), at 5.8%: a product that belongs there but is entered here, or the reverse, changes the duty by 5.8 percentage points.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 58% of the 624 tariff lines in chapter 85. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
The other lines in the same group are 8539.29.10 (christmas-tree lamps, 5.8%), 8539.29.20 (lamps having glass envelopes not over 6.35 mm in maximum…, 5.2%) and 8539.29.40 (designed for a voltage exceeding 100 V, 2.6%).
Goods from countries without normal trade relations pay the column 2 rate of 20% instead of nothing, so origin decides between free entry and a 20% duty.
