Demurrage is a penalty charged by the port or shipping company for not clearing and picking up goods on time after they arrive. To avoid it: send customs documents in advance and ensure the recipient is prepared with duties and import qualifications.
The battery pack is 30–50% of an EV's value, so its inspection should be the most detailed part of the pre-shipment check. Require these items: 1. BMS data readout: state of health (SOH), full-charge voltage, cell voltage deviation, cycle count, and fast-charging percentage. SOH above 90% is good; below 80% means a costly pack replacement is approaching. 2. Physical inspection: check the underbody for pack dents, coolant leaks from the battery cooling circuit, and corrosion on high-voltage connectors. 3. Range test: a real drive of at least 30–50 km, comparing energy consumption against the rated figure. A pack with poor cells overheats and depletes fast. 4. Charging test: verify both AC and DC charging work, and record charging speed and any error messages. Get the raw diagnostic data, not just a summary. If the inspector won't share the BMS report, assume the battery is the reason why.
Customs clearance at destination is usually handled by a licensed customs broker, not the exporter. You can hire one yourself or use a broker recommended by your shipping agent. The typical flow: your broker files the import declaration using the documents the exporter must provide — the commercial invoice, packing list, bill of lading, and the certificate of origin. Depending on your country's rules, you will also need to pay import duty, VAT or sales tax, and any excise or environmental levies before the car is released. Things that commonly delay clearance: mismatched VIN numbers between documents, missing pre-shipment inspection certificates (required in some African and Middle Eastern countries), or non-compliance with your country's used-car import age limits. Budget 3–10 working days for clearance after the vessel arrives, plus storage fees if documents are incomplete. Tip: send all documents to your broker for review before the ship departs China — fixing errors at origin is much cheaper than demurrage at destination.
