HS Code 8409Parts suitable for use solely or principally with the engines of heading no. 8407 or 8408
3 six-digit codes · Heading 9 of 86 in Chapter 84 · World Customs Organization Harmonized System
HS code 8409 is the customs heading for engine parts, meaning parts made for the piston engines of headings 8407 and 8408. Use this page to see what it covers and which six-digit code fits your part.
“Parts suitable for use solely or principally with the engines of heading no. 8407 or 8408” divides three ways under heading 8409 — 840910, 840991 and 840999. Each carries its own customs description, and the exact wording below is what a classification has to match. The heading is number 9 of 86 in Chapter 84, Machinery and mechanical appliances, boilers, nuclear reactors; parts thereof, which runs to 538 six-digit codes in all.
Six-digit codes under heading 8409
| HS Code | Import–export description |
|---|---|
| 840910 | Engines; parts of aircraft engines (spark-ignition reciprocating or rotary internal combustion piston engines) |
| 840991 | Engines; parts, suitable for use solely or principally with spark-ignition internal combustion piston engines (for other than aircraft) |
| 840999 | Engines; parts for internal combustion piston engines (excluding spark-ignition) |
What HS code 8409 covers
The heading is about parts, not whole engines. It covers parts of internal combustion piston engines, as long as the part is suitable for use solely or principally with those engines. Heading 8407 holds reciprocating or rotary internal combustion piston engines. Heading 8408 holds compression-ignition engines, which most people call diesel engines.
So 8409 never covers a complete engine. It covers the pieces that go in or on one. A part that fits many kinds of machines often belongs in another heading. Many buyers and sellers search for this as the HSN code 8409. The digits are the same.
Its three subheadings split the parts by engine type: aircraft engine parts, spark-ignition engine parts, and parts for all other piston engines.
How to choose between 840910, 840991 and 840999
Each six-digit code has its own customs wording, and your part has to match it. Work through the questions in this order.
- First, is the part for an aircraft engine? Aircraft engine parts go to 840910.
- Next, is the part for a spark-ignition piston engine that is not in an aircraft? Then it goes to 840991. This is the code for spark-ignition engine parts outside aviation.
- If the engine is a piston engine but not spark-ignition, use 840999. Compression-ignition (diesel) engine parts land here.
- If you cannot tell which engine the part is for, check the part's design and its listed use. Then try the HS code classifier before you file.
8409 vs 8407, 8408 and 8411: parts or complete engines
The simplest test is this: is it the engine, or a part of the engine? A complete spark-ignition or rotary piston engine goes to heading 8407. Parts for either kind go to 8409.
Jet engines are a different case. Turbo-jets, turbo-propellers and other gas turbines sit in heading 8411, so they do not belong here. Engines and motors not named elsewhere, such as reaction engines, go to heading 8412.
Some parts are not covered by 8409 at all. Crankshafts and other transmission shafts are listed in heading 8483. Machinery parts with no electrical features and no better home are listed in heading 8487. Read the heading text before you decide, because the wording "solely or principally" is what counts.

HS Code 8409: common questions
What is the HS code for diesel engine parts?
Parts for diesel engines go to 840999, which covers piston engine parts excluding spark-ignition. A complete diesel engine is not a part and goes to heading 8408.
What is the difference between HS code 8407 and 8409?
Heading 8407 covers complete reciprocating or rotary piston engines. Heading 8409 covers parts made for those engines and for the diesel engines of 8408.
Which code do spark-ignition engine parts use?
If the engine is for an aircraft, use 840910 instead.
Where can I check duty on 8409 parts?
This page does not list duty or tax rates. Check the official tariff of the importing country, and use the HS code classifier to confirm your code first.
