Quartz reactor tubes and holders designed for insertion into diffusion and oxidation furnaces for production of semiconductor wafers
Analysis
HTS 7020.00.30 covers quartz reactor tubes and holders designed for insertion into diffusion and oxidation furnaces for production of semiconductor wafers under heading 7020 (other articles of glass).
Neighbouring lines carry rates from 5% to 6.6%, so the exact line matters. The widest gap is with 7020.00.40 (glass inners for vacuum flasks or for other vacuum vessels), at 6.6%: a product that belongs there but is entered here, or the reverse, changes the duty by 6.6 percentage points.
Goods from countries without normal trade relations pay the column 2 rate of 55% instead of nothing, so origin decides between free entry and a 55% duty.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 28% of the 192 tariff lines in chapter 70. 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 7020.00.40 (glass inners for vacuum flasks or for other vacuum vessels, 6.6%) and 7020.00.60 (other articles of glass: other, 5%).
