HS-4 · Heading
8407 — Reciprocating or rotary internal combustion piston engines
Chapter 84: Nuclear reactors, boilers, machinery
Plain-language overview
Use HS-4 8407 when importing or exporting reciprocating or rotary internal combustion piston engines. For example, if you're shipping a spark-ignition engine for an aircraft, this is the correct code. It encompasses various engines used in vehicles, boats, and other machinery.
When determining the right HS-6 code, consider the specific application of the engine. For instance, 840710 is for aircraft engines, while 840721 covers outboard motors for marine propulsion. If your engine is not an outboard motor but still used in marine applications, 840729 is the appropriate choice.
Another key distinction is based on the cylinder capacity for vehicle engines. If you're dealing with engines under 50cc, use 840731. For those exceeding 50cc but not surpassing 250cc, select 840732. This pattern continues up to 840734 for engines exceeding 1000cc.
