8407.10.00

Analysis

HTS 8407.10.00 covers spark-ignition reciprocating or rotary internal combustion piston engines: aircraft engines under heading 8407 (spark-ignition reciprocating or rotary internal combustion piston engines). US Customs collects import statistics for it under 4 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 8407.34.48 (to be installed in vehicles of subheading 8701.21, 8701.22, 8701.23…), at 2.5%: a product that belongs there but is entered here, or the reverse, changes the duty by 2.5 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.

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.
