HS Code for Starter-generator

Starter-generators are classified under HS code 8511.40 because they are dual-purpose electrical machines used for both starting internal combustion engines and generating electricity once the engine is running. Heading 8511 covers electrical ignition or starting equipment for spark-ignition or compression-ignition engines. Subheading 8511.40 specifically includes starter motors and dual-purpose starter-generators. These components are essential for the operation of modern vehicles, particularly those with start-stop technology or mild hybrid systems. The classification is based on the primary function of the device as part of the engine's starting system, which takes precedence over general motor or generator headings in Chapter 85.

Products Included

• Integrated Starter Generators (ISG) for hybrid vehicles
• Combined starter-alternator units
• Dynastarters for small engines
• Starter motors for passenger cars
• Heavy-duty starter motors for diesel engines
• Belt-driven starter generators
• Crankshaft-mounted starter generators

Common Misclassification

Starter-generators are often misclassified under HS code 8501, which covers general-purpose electric motors and generators. However, because these units are specifically designed for internal combustion engines, Heading 8511 is more specific and thus takes precedence according to GRI 3(a). Another common error is using HS code 8511.50, which is for other generators (alternators) that do not have a starting function. If the unit performs both starting and generating, 8511.40 is the mandatory classification.

FAQ

What is the HS code for starter-generator?

The HS code for dual-purpose starter-generators used for internal combustion engines is 8511.40.

What is the difference between 8511.40 and 8511.50?

HS code 8511.40 includes units that can start the engine (starter motors and starter-generators), while 8511.50 is for generators (like alternators) that only produce power and cannot start the engine.
