Analysis
HTS 8406.90.70 covers blades, rotating or stationary under heading 8406 (steam turbines and other vapor turbines, and parts thereof).
Neighbouring lines carry rates from duty-free to 5%, so the exact line matters. The widest gap is with 8406.90.45 (of steam turbines: other), at 5%: a product that belongs there but is entered here, or the reverse, changes the duty by 5 percentage points.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 61% of the 823 tariff lines in chapter 84. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
Goods from countries without normal trade relations pay the column 2 rate of 27.5% instead of nothing, so origin decides between free entry and a 27.5% duty.
Census statistics map these goods to NAICS 333611 (Turbine and Turbine Generator Set Units Manufacturing), an industry of 199 US establishments employing 25,748 people. That is the industry code a US manufacturer of the same product would normally use.
