About heading 8407

Spark-ignition reciprocating or rotary internal combustion piston engines

Heading 8407 covers spark-ignition reciprocating or rotary internal combustion piston engines, meaning gasoline-type engines with spark plugs rather than diesel engines. The heading splits first by end use: aircraft engines (8407.10), marine propulsion engines (8407.21 and 8407.29), engines for vehicles of chapter 87 (8407.31 through 8407.34, split by cylinder capacity), and all other engines (8407.90). Most lines in the heading carry a general (MFN) rate of Free, with a 2.5% rate on certain vehicle engines of 250 cc and above.

Frequently asked questions

What is the HTS code for a small outboard marine engine under 22.38 kW?

Outboard motors under 22.38 kW are classified under 8407.21.00.40. The general (MFN) rate for that line is Free.

What is the duty on a spark-ignition engine to be installed in a passenger car with 1,500 cc cylinder capacity?

A new engine of that size for heading 8703 vehicles falls under 8407.34.18.00. The general (MFN) rate is 2.5%.

How do I classify a gasoline engine for agricultural or horticultural machinery?

Engines for agricultural or horticultural machinery go in 8407.90.10, split by power and cooling. For example, an air-cooled engine over 37.3 kW is 8407.90.10.60 at a general (MFN) rate of Free, and an engine not exceeding 37.3 kW at 4,476 W or more is 8407.90.10.20, also Free.
