A vehicle proforma invoice must list specific powertrain details such as engine displacement or battery capacity, fuel or energy type, and transmission to ensure accurate customs classification and tax assessment.
While a proforma invoice (PI) contains many sections, the powertrain information is one of the most scrutinized by customs officials. These details are not just for identification; they directly determine the import duties, taxes, and environmental levies applied to the vehicle in your destination country. Inaccurate or incomplete data can lead to significant delays, fines, or even the rejection of your shipment.
Key Powertrain Details for ICE Vehicles
For petrol and diesel vehicles, customs authorities typically require the following information to classify the vehicle and calculate duties:
- Engine Displacement: This must be listed precisely in cubic centimeters (cc) or liters (L). Many countries have tax brackets based directly on engine size, making this the most critical data point.
- Fuel Type: Clearly state whether the vehicle uses Petrol (Gasoline) or Diesel. This is essential for emissions compliance and environmental taxation.
- Transmission Type: Specify if the transmission is Automatic (AT), Manual (MT), or another type like CVT. This can sometimes affect the vehicle's classification.
- Drive Type: Listing the drive system (e.g., FWD, RWD, AWD, 4WD) helps customs correctly categorize the vehicle, especially for SUVs and commercial trucks.
Essential Powertrain Details for Electric Vehicles (EVs)
For New Energy Vehicles (NEVs), the required details shift from combustion to electrical systems. Providing clear information is vital for qualifying for potential green energy tax credits or subsidies.
- Battery Capacity: Stated in kilowatt-hours (kWh), this is the EV equivalent of engine displacement. It is often the primary factor for calculating import incentives and taxes.
- Motor Power Output: Listed in kilowatts (kW), this detail helps classify the vehicle's performance category.
- Energy Type: Clearly state "Electric" or "Plug-in Hybrid" (PHEV) to ensure the vehicle is processed under the correct regulations.
- Charging Standard: While not always mandatory on the PI, including the charging standard (e.g., GB/T, CCS) is helpful for homologation and market readiness.
