The lifespan of rubber sealing strips for frameless doors is usually only 4-5 years. We carefully press the sealing strip at the edge of the roof to check for loss of elasticity and use a high-pressure water gun to wash the seams of the windows to check for direct water leakage due to aging.

The 12V battery is small but critical: when it dies, the car cannot start, unlock, or charge. Used EVs often have weak 12V batteries because they sit on lots for months. Before shipping, ask the exporter to: 1. Measure the battery voltage after the car has rested overnight. It should read around 12.4-12.8V; anything under 12.2V means the battery is degraded. 2. Start the car and check that the charging system holds 13.8-14.4V, confirming the DC-DC converter works. 3. Scan for stored fault codes related to low voltage, which indicate the battery has been deeply discharged repeatedly. During ocean freight, the battery slowly self-discharges. Ask that it be disconnected or kept on a maintainer before loading, and budget for a replacement after arrival if the battery is over 3 years old. A new 12V battery costs little compared to being stranded at the port.

As the importer, you mainly need to bear the following costs at the destination port: import duties, VAT or GST, terminal handling charges, local customs clearance fees, and inland logistics costs from the port to your company. Please consult your local customs broker before placing an order to accurately calculate the total landing costs.
