Dear Ms. Lee,
It is good to hear from you again. I really do understand your concern. Please let me explain the shift in delivery schedule to you in detail.
You are correct that when the Tesla just boarded the vessel to Hong Kong, the estimated time of arrival was end of August to September. On the 12th of August, when the vessel was close to arrival, the Chinese city of Tianjin encountered a series of explosions. The Tesla itself was not damaged as it was still at sea. This incident, however, led to Chinese port authorities instantly enacting stricter import-export control standards, where shipments with "Dangerous" goods arriving at Chinese ports must be properly labelled. Tesla, being an electric car with a 70kWh to 90Kwh battery capacity is classified under one of the sub-categories of a "Dangerous" good. And because Tesla vehicles are classified under a sub-category of a “Dangerous” good, and also because the shipment has already left port in the US and was not labelled, the shipment had to be re-routed to another country. And then from there, be shipped to Hong Kong. This ultimately is the main cause in the shift in arrival times.
Please refer to the links below as evidence of the impact in shipment arrival times as the result of the Tianjin incident.

Currently, the Tesla has already arrived in Hong Kong. Because this particular Tesla is the first of its kind with its unique configuration, the Hong Kong customs has requested further inspection of the vehicle to ensure that it is road-worthy. This has further caused a shift in delivery schedule. To ensure that you are well aware of the situation, I will update you again by the end of next week.
