Quartz reactor tubes and holders designed for insertion into diffusion and oxidation furnaces for production of semiconductor wafers
Analysis
HTS 7017.10.30 covers quartz reactor tubes and holders designed for insertion into diffusion and oxidation furnaces for production of semiconductor wafers under heading 7017 (laboratory, hygienic or pharmaceutical glassware, whether or not graduated or calibrated).
Within this group the rate runs from duty-free to 6.7%. Compared with 7017.90.50 (other: other), which pays 6.7%, a misclassification either way moves the duty by 6.7 percentage points.
Goods from countries without normal trade relations pay the column 2 rate of 50% instead of nothing, so origin decides between free entry and a 50% duty.
The normal trade relations rate here is zero, shared by about 28% of the 192 tariff lines in chapter 70, 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.
The other lines in the same group are 7017.10.60 (of fused quartz or other fused silica: other, 4.6%), 7017.20.00 (of other glass having a linear coefficient of expansion not…, 6.7%), 7017.90.10 (microscope slides and micro cover glasses, duty-free) and 7017.90.50 (other: other, 6.7%).
