HS Code for Spark plug

Spark plugs are classified under HS code 8511.10. This classification is governed by Chapter 85, which includes electrical machinery and equipment and parts thereof. Heading 8511 specifically covers electrical ignition or starting equipment of a kind used for spark-ignition or compression-ignition internal combustion engines. Even though a spark plug is a component of an engine, it is classified in Chapter 85 rather than Chapter 84 because it is an electrical component with a specific function in the ignition system. Subheading 8511.10 is the dedicated code for spark plugs. These devices function by delivering an electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark. The classification remains consistent regardless of whether the spark plug is for an automobile, a motorcycle, a lawnmower, or a stationary industrial engine. The construction typically involves a central electrode, an insulator, and a metal shell, all of which are considered part of the finished spark plug assembly.

Products Included

• Standard automotive spark plugs
• Iridium spark plugs
• Platinum spark plugs
• Resistor spark plugs
• Marine engine spark plugs
• Small engine spark plugs (chainsaws, mowers)

Common Misclassification

Spark plugs are sometimes incorrectly classified under 8409.91 as general engine parts. However, Note 2 to Section XVI and the specific heading 8511 dictate that electrical ignition equipment takes precedence. They are also confused with glow plugs, which are used in diesel engines and are classified under HS code 8511.80. Ignition coils, which work with spark plugs, are classified under 8511.30.

FAQ

What is the HS code for Spark plug?

The specific HS code for spark plugs is 8511.10.

Are glow plugs for diesel engines classified here?

No, glow plugs are classified under HS code 8511.80 as "other" ignition equipment, as they function through heat rather than a spark.
