Shenzhen express parcel to Bangkok, Thailand
Fedex Thailand has an advantage, about 4 to 5 days to arrive. Fedex is a door-to-door service with stops in major Chinese cities. You can contact the official customer service directly. However, the official price is relatively high, can be mailed through the transport company, so the freight will be much cheaper.
I suggest you try this:
Contact a transshipment company in China (which can send goods from home to abroad).
Send what you need to this company.
Generally, they will provide value-added services such as receiving/checking/distributing/packing/sealing for free.
After confirming the weight, the freight and channel shall be confirmed.
Make delivery (be careful to provide commercial invoice and waybill).
After delivery, the tracking number will be obtained for online tracking.
After the goods arrive at the Thai customs, please pay attention to the customs clearance. There may be tariff, the specific notice of the customs shall prevail.
After customs clearance, you can wait for the delivery.
Benefits: fast and safe delivery.
