Heading 8407Reciprocating or rotary internal combustion piston engines

Chapter 84: Nuclear reactors, boilers, machinery

Plain-language overview

Use HS-6 840790 when importing or exporting rotary internal combustion piston engines designed for applications other than aircraft or marine propulsion. For example, this code applies to engines used in generators or industrial machinery.

This code specifically covers rotary internal combustion piston engines, distinguishing them from other types like reciprocating engines classified under HS-6 840710. If your engine is designed for marine use, you would look at HS-6 840810 instead.

Engines classified under this code can be found in various applications, including construction equipment, agricultural machinery, and power generation systems. They typically feature a rotary design, which offers different performance characteristics compared to traditional piston engines.

When classifying your product, ensure it meets the specifications outlined for rotary engines. If you are unsure, consulting with a customs broker can help clarify the correct classification.
