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.

Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.

If the delays are due to policy-related force majeure like customs system upgrades, or if our documentation errors lead to short shipments, all additional demurrage and storage fees incurred at ports within China will be borne by sellwellauto, and the buyer will not have to pay a cent.
