What is HS-4 8409 used for?
Use this as a comparison hint, then confirm the final decision with legal notes and country-specific rules.
HS-4 · Heading
8409 — Parts suitable for use solely or principally with the engines of heading no. 8407 or 8408
Chapter 84: Nuclear reactors, boilers, machinery
Plain-language overview
Use HS-4 8409 when importing parts specifically designed for engines classified under heading 8407 or 8408. For example, if you're importing a fuel injector meant for a spark-ignition aircraft engine, this code applies.
To differentiate between the subheadings, consider the engine type. HS-6 840910 is for parts of aircraft engines, while HS-6 840991 covers parts for spark-ignition engines not used in aircraft. If your part is for a non-aircraft engine, you’ll likely use 840991.
If your part is for a non-spark-ignition internal combustion engine, then HS-6 840999 is the correct code. This distinction is crucial, as using the wrong subheading can lead to customs delays or penalties.
