HS Code for Spark ignition engine parts

Parts suitable for use solely or principally with spark-ignition internal combustion piston engines are classified under HS code 8409.91. This classification follows the guidelines of Chapter 84, which covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8409 is a specific "parts" heading for engines described in headings 8407 (spark-ignition) or 8408 (compression-ignition). Subheading 8409.91 is specifically for parts of spark-ignition engines, excluding those used in aircraft. Classification under this code requires that the part does not have a more specific heading elsewhere in the nomenclature. The "solely or principally" rule is critical; if a part is used across multiple types of machinery, its classification might change. However, specialized components like pistons, cylinder blocks, and cylinder heads for petrol engines are typically found here. This code excludes parts that are specifically mentioned in other chapters, such as electrical components (Chapter 85) or gaskets (Chapter 8484).

Products Included

• Pistons and piston rings
• Cylinder blocks and heads
• Connecting rods
• Carburetors
• Intake manifolds
• Valve covers
• Fuel injectors (for spark-ignition)

Common Misclassification

Parts for diesel engines (compression-ignition) are often misclassified here but belong under HS code 8409.99. General vehicle parts that are not engine-specific, such as bumpers or body panels, are classified under 8708. Furthermore, electrical parts like spark plugs (8511.10) or ignition coils (8511.30) are classified in Chapter 85, even though they are essential engine components.

FAQ

What is the HS code for Spark ignition engine parts?

The HS code for parts used solely or principally with spark-ignition engines is 8409.91.

Are engine valves classified under 8409.91?

No, intake and exhaust valves are generally classified under HS code 8481.80 as they are considered valves/taps/cocks, which have a more specific heading.
