Analysis
HTS 8514.11.00 covers hot isostatic presses under heading 8514 (industrial or laboratory electric furnaces and ovens (including those functioning by…).
Within this group the rate runs from duty-free to 4.2%. Compared with 8514.20.60 (microwave ovens: other), which pays 4.2%, a misclassification either way moves the duty by 4.2 percentage points.
Goods from countries without normal trade relations pay the column 2 rate of 35% instead of nothing, so origin decides between free entry and a 35% duty.
The normal trade relations rate here is zero, shared by about 58% of the 624 tariff lines in chapter 85, 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 333994 (Industrial Process Furnace and Oven Manufacturing), an industry of 319 US establishments employing 11,055 people. That concordance is how imports of this line are compared with US output.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
