Customs Clearance of Aircraft Engines in Iran (HS + Documents and Permits)
Aircraft engines, also known as airplane engines, are one of the key components in the aviation and aerospace industry, responsible for providing thrust power. These engines are produced in various types, each designed according to the type of aircraft and its mission, with different structures and performance. Types include reciprocating engines, turbine engines, jet engines, and rocket engines. Each has unique characteristics and applications, which will be discussed in more detail below.
For an estimate of time and cost for clearing aircraft/helicopter engines (reciprocating, turbine, jet, rocket), contact the experts at Saba Tarkhis.
Immediate Free Consultation1) Types of Aircraft Engines
Reciprocating Engine: These are among the oldest and most well-known aircraft engines, mainly used in light and training aircraft. In a reciprocating engine, fuel combustion (usually gasoline or aviation fuel) inside the cylinders causes pistons to move back and forth. This movement is converted into rotary motion via the crankshaft, providing the power needed to rotate the propeller. Advantages include simple design and lower production/maintenance costs compared to other types. However, limitations such as lower efficiency and power restrict their use to light, short-range aircraft.
Turbine Engines: These come in several categories and are widely used in airplanes and helicopters. Subtypes include:
Turbojet: The first type of turbine engine, used in high-speed aircraft like fighter jets and early passenger planes. Operation is based on air compression in the compressor, fuel combustion in the combustion chamber, and expulsion of hot gases at high speed from the nozzle, generating thrust. Turbojets are still used in military and some commercial aircraft due to their high efficiency at high speeds and altitudes.
Turbofan: Widely used in modern passenger aircraft, combining a large fan at the front with the turbine. This design increases efficiency and reduces fuel consumption and noise. Turbofans perform better at subsonic speeds, making them the engine of choice in most commercial and military aircraft.
Turboprop: Designed for regional and short-haul aircraft, where a turbine drives a propeller. Turboprops are highly efficient at low to medium speeds, offering a cost-effective alternative for short routes.
Turboshaft: Mainly used in helicopters and VTOL aircraft, these engines deliver mechanical power directly from the turbine to the output shaft, providing the power needed to rotate helicopter rotors.
Jet Engine: A turbine engine capable of producing high thrust at high speeds and altitudes, widely used in fighter jets and high-speed commercial aircraft. They compress air, combust fuel, and expel hot gases at high speed, generating tremendous thrust. While highly efficient at supersonic speeds, their high fuel consumption limits them to specific applications.
Rocket Engine: Among the most powerful propulsion systems, used mainly in spacecraft and missiles. Unlike other engines, rocket engines use onboard fuel and oxidizer and can operate in space vacuum. They generate immense thrust, enabling launches into space, but are costly to build/maintain and consume fuel rapidly.

2) Technical Notes on Aircraft Engine Clearance
Customs Tariff or HS Code: Aircraft engines are classified under different HS Codes based on type, use, and technical features. For example:
Reciprocating Engines: Classified under HS Code 8407.
Turbine and Jet Engines: Classified under HS Code 8411. Accurate knowledge of these codes is essential for calculating duties, taxes, and tariffs, directly impacting total import costs.
Import Permits and Standards: Due to their critical role in flight safety and strict standards, importing aircraft engines requires special permits from regulatory bodies. These include technical approval certificates from the Civil Aviation Organization, Ministry of Defense, and international standardization bodies like EASA (European Union Aviation Safety Agency) and FAA (Federal Aviation Administration). Any technical non-compliance can result in shipment rejection or seizure at customs.

Reciprocating Engine: Reciprocating engines are among the oldest and best-known aircraft engines, mainly used in light and training aircraft. In a reciprocating engine, fuel combustion (usually gasoline or aviation fuel) inside the cylinders causes the pistons to move back and forth. This motion is converted into rotational motion via the crankshaft, providing the driving force to turn the propeller. One advantage is simpler design and lower production and maintenance costs compared to other types. However, limitations such as lower efficiency and limited power relative to turbine engines restrict their use to light, short-range aircraft.
Turbine Engine: Turbine engines fall into several categories and are used across a wide range of airplanes and helicopters. This category includes the following types:
Turbojet: The first type of turbine engine, used in high-speed aircraft such as fighter jets and early passenger airplanes. Operation is based on compressing air in the compressor, combusting fuel in the combustion chamber, and expelling hot gases at very high speed through the exhaust nozzle. This process generates thrust that propels the aircraft forward. Owing to high efficiency at high speeds and altitudes, turbojets are still used in military and some commercial aircraft.
Turbofan: Widely used in modern passenger aircraft thanks to the large front fan combined with the turbine. This design increases efficiency and reduces fuel consumption and noise. With a large fan compressing a significant portion of incoming air, turbofans perform better at subsonic speeds and therefore are used in most modern commercial and military aircraft.
Turboprop: Particularly suitable for regional and short-haul aircraft, where the turbine drives a propeller. Turboprops have high efficiency at low to medium speeds and offer a cost-effective alternative to jet engines on short routes.
Turboshaft: Mainly used in helicopters and vertical take-off and landing (VTOL) aircraft, these engines deliver high mechanical power. By transmitting power directly from the turbine to the output shaft, turboshafts provide the power required to rotate helicopter rotors.
Jet Engine: A type of turbine engine that, thanks to its ability to produce high thrust at high speeds and altitudes, is used in fighter jets and high-speed commercial aircraft. By compressing air, combusting fuel, and expelling hot gases at high speed through the nozzle, it generates tremendous thrust that propels the aircraft at very high speeds. A key advantage is high efficiency at supersonic speeds; however, high fuel consumption at lower speeds limits use to specific applications.
Rocket Engine: Among the most powerful propulsion types, used mainly in spacecraft and missiles. Unlike other aircraft engines that need air for combustion, rocket engines use onboard fuel and oxidizer and can operate in the vacuum of space. They generate immense thrust enabling launch and travel in space. However, high production and maintenance costs and rapid fuel consumption are major challenges.2) Technical Notes for Clearing Aircraft Engines
Customs Tariff or HS Code: Aircraft engines are classified under different HS Codes based on type, application, and technical characteristics. For example:
Reciprocating Engines: Classified under tariff heading 8407.
Turbine (Turbine Engines) and Jet (Jet Engines): Classified under tariff heading 8411. Accurate identification of these codes is crucial for determining customs duties, taxes, and related tariffs, which directly affect overall import costs.
Import Permits and Required Standards: Because of their vital role in flight safety and the complex standards that must be met, importing aircraft engines requires obtaining specific permits from various regulatory bodies. These include technical qualification certificates from the Civil Aviation Organization, the Ministry of Defense, and international standardization bodies such as EASA (European Union Aviation Safety Agency) and the FAA (Federal Aviation Administration). Moreover, any technical defect or non-compliance with international standards can lead to the shipment being returned or seized at customs.Engine Type Application/Short Description HS Code Reciprocating Light/training aircraft; propeller propulsion 8407 Turbine/Jet Turbofan/Turbojet/Turboprop/Turboshaft 8411 Exact line classification depends on power (kW/lbf), application (Fixed/Rotary/VTOL), new/used status, and whether it is a component/module.
