Singapore regulations & registration

COE Category

COE categories segment Singapore vehicles by engine and OMV: Cat A (small cars), Cat B (larger or luxury cars), Cat C (commercial), Cat D (motorcycles), Cat E (open).

The category structure: Cat A — engines ≤1600cc and 130 bhp OR EVs ≤110 kW; Cat B — anything larger or more powerful; Cat C — goods vehicles and buses; Cat D — motorcycles; Cat E — any vehicle category.

Cat B COE prices are typically the highest, reflecting demand for larger and luxury vehicles. Cat A prices vary with imported small car supply.

For workshops, COE category roughly correlates with customer segment: Cat A drivers are budget-conscious; Cat B drivers are more likely to invest in premium tint and PPF.
