Analysis
HTS 7002.20.10 covers of fused quartz or other fused silica under heading 7002 (glass in balls (other than microspheres of heading 7018), rods or tubes, unworked).
Within this group the rate runs from duty-free to 6%. Compared with 7002.39.00 (tubes: other), which pays 6%, a misclassification either way moves the duty by 6 percentage points.
Goods from countries without normal trade relations pay the column 2 rate of 40% instead of nothing, so origin decides between free entry and a 40% 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.
Census statistics map these goods to NAICS 327212 (Other Pressed and Blown Glass and Glassware Manufacturing), an industry of 376 US establishments employing 10,738 people. That concordance is how imports of this line are compared with US output.
