HS-6 · Subheading
840910
Engines; parts of aircraft engines (spark-ignition reciprocating or rotary internal combustion piston engines)
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-6 840910 when importing or exporting parts specifically designed for spark-ignition reciprocating or rotary internal combustion piston engines used in aircraft. For example, this code applies to a shipment of cylinder heads or crankshafts intended for aircraft engines.
This code is distinct from HS-6 840920, which covers parts for compression-ignition engines. If your parts are designed for aircraft engines but are not spark-ignition types, you should consider the 840920 classification instead.
The 840910 subheading narrows down to parts that are essential for the operation of specific aircraft engines, ensuring that only those components meant for these engines are classified here. This includes items like fuel pumps and ignition systems.
When determining the correct classification, consider whether the part is solely or principally used with the engines of headings 8407 or 8408. If it fits this criterion, 840910 is likely the right choice.
