Taobao official forwarders used to allow sensitive items but charge more. Now it seem like they totally ban them.

If you find agents, some will do it but shipping cost will be higher. Not sure if kastam will block or not.

Sensitive items are usually battery, radio frequency stuffs such as wifi router (I dont really get this though, tried buying a router from Xiaomi and they said prohibited. But I managed to buy the wifi repeater), magnetic stuffs, liquid stuffs.

Some chargers also are being rejected. I did successfully bought an anker multiple port charger previously but later my xiaomi car charger was rejected by warehouse.

It is really hard to buy anything at Taobao nowadays because of these restrictions. You can try finding them on Taobao section in Lazada. Some of the items that were rejected in Taobao was received successfully using Taobao@Lazada. For example, got an air mouse with rechargeable batteries without much problem.
