Direct mail means that some foreign e-commerce companies support direct mail to China. When you photograph it, the goods will be sent directly from America to your home. For example, some commodities in Meiya support direct mail, and these commodities need customs declaration in China. Customs needs information such as product name, unit price and consignee. It will be released after verification, so this information is finally handed over to the customs.

2. Direct mail means that overseas e-commerce companies don't support direct mail to China or must mail the goods to an address (individual or freight forwarding company) in the local country before forwarding them to you. There are two situations when mailing: 1) overseas direct mail to your home, such as USPS, DHL, UPS, FedEx, etc. Because these couriers belong to individuals, they are not. However, you also need to provide the payee's ID card, because you have to declare it. 2) Overseas freight forwarders come to your home. In this case, freight forwarders generally have their own transshipment warehouses in another place overseas, and some of these countries and regions do not need this information for mailing because they have cooperation with China, such as Singapore, or freight forwarders have their own import and export bills to avoid these processes, so they do not need identity information!

Second, what should I do if I am worried about information leakage?

Avoidance method: 1) If you have to provide it, just copy the front and back of your ID card, and write it by hand: for customs declaration only, and sign it with the invalid back.

This can basically avoid the abuse of ID cards.

2) I'm really worried about information leakage, which shows that you care about this information. Then ask the purchasing agent to send the things to him. I will send it to you by SF Express when I arrive in China.
