About HS Code 840790

This HS code covers spark-ignition rotary internal combustion piston engines, excluding those for aircraft or marine propulsion. This category primarily includes Wankel engines used in specialized automotive applications, as well as smaller rotary engines for industrial equipment, generators, or unmanned aerial vehicles (UAVs) that are not classified as aircraft propulsion. The international trade for these engines is niche compared to conventional reciprocating engines, driven by specific performance requirements like high power-to-weight ratio, compact size, and smooth operation. Exporters are often specialized manufacturers in countries with advanced engineering capabilities. Importers include manufacturers of specialized vehicles, industrial machinery, and defense contractors. Key trade considerations involve engine efficiency, durability, emissions, and the availability of parts and servicing, as rotary engines have unique design characteristics that require specialized expertise.

Products Under This Code

Wankel automotive engines, Rotary UAV engines, Rotary generator engines, Industrial rotary engines, Experimental rotary engines, Compact rotary engines, Range extender rotary engines

Real World Examples

Mazda 13B-MSP Renesis engine, UAV Engines Ltd. AR801 engine, LiquidPiston X-Engine, Freedom Motors FR-80 engine, Norton NRV588 engine

Common Misclassification

This code is distinct due to its "rotary" engine type and the exclusion of aircraft (840710) and marine propulsion (84072x), and should not be confused with reciprocating engines (84073x).
