View full HS code details

HS code 8409.99 is the designated classification for parts suitable for use solely or principally with compression-ignition internal combustion piston engines. According to Note 2 to Section XVI of the Harmonized System, parts of machines are generally classified in their respective headings if they are not excluded by Section or Chapter notes. Heading 8409 is specifically provided for parts of engines falling under headings 8407 or 8408. Within this heading, a distinction is made between parts for spark-ignition engines (8409.91) and all other engines (8409.99). Since diesel engines operate on compression ignition, their components—such as fuel injectors, cylinder heads, pistons, and rings—are classified under 8409.99. This classification applies to parts that do not have a more specific heading elsewhere in the nomenclature (such as gaskets of 8484 or crankshafts of 8483) and are identifiable as being specifically for diesel engines. The classification remains 8409.99 regardless of whether the engine is used for a vehicle, a ship, or a stationary generator.

Products Included

  • Pistons for diesel engines
  • Cylinder heads for compression-ignition engines
  • Fuel injectors and injection nozzles
  • Cylinder liners for diesel blocks
  • Inlet and exhaust valves for diesel engines

Common Misclassification

A common error is classifying diesel engine parts under 8409.91, which is strictly for spark-ignition (petrol) engines. Another frequent mistake is attempting to classify these parts under 8708, which covers general parts and accessories for motor vehicles. However, Note 2(e) to Section XVII explicitly excludes internal combustion piston engines and parts thereof from Chapter 87, directing them back to heading 8409.
