You don't know how it works?
Pay attention because below we'll explain what it is and all its advantages.
What is Cainiao
Cainiao is a company created by the Alibaba group, in order to help with shipments, and to which AliExpress belongs.
This way, they ensure the management of your items from start to finish and at the same time, it allows us to find very economical shipments, which is always good news for us.
Another popular Cainiao shipping method is the Cainiao Standard for Special Goods.
What type of shipping is “Cainiao Warehouse Standard Shipping”?
For some time now, AliExpress has set up a number of warehouses in Spain, Belgium, France, Poland, Malaysia and the Czech Republic.
How long does it take for “Cainiao Warehouse Standard Shipping” shipments to arrive home?
Delivery time varies between 3 and 7 days, depending on where the item is in stock. In case the warehouse is in your country, the delivery time is only 3 days maximum (it may even arrive sooner).
For other EU countries, the delivery time is a bit longer, 7 days. These shipments work very well and also have a number of advantages that we explain below:
What are the advantages of this shipment over others from AliExpress?
In addition to speed, if you use “Cainiao Warehouse Standard Shipping”, you can be sure that your package will not be held by customs and you will not have to pay VAT or duties.
As we explained the other day, these taxes are only payable on items imported from outside the European Union, so in this case you are free of this concern.
