8411.91.10

Analysis

HTS 8411.91.10 covers cast-iron parts, not advanced beyond cleaning, and machined only for the removal of fins, gates, sprues and risers or to permit location in finishing machinery under heading 8411 (turbojets, turbopropellers and other gas turbines, and parts thereof). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in number of items.

Neighbouring lines carry rates from duty-free to 2.5%, so the exact line matters. The widest gap is with 8411.82.80 (of a power exceeding 5,000 kW: other), at 2.5%: a product that belongs there but is entered here, or the reverse, changes the duty by 2.5 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.

Census statistics map these goods to NAICS 336412 (Aircraft Engine and Engine Parts Manufacturing), an industry of 440 US establishments employing 75,499 people. That is the industry code a US manufacturer of the same product would normally use.
