Can international students buy luxury goods and electronic products (mobile phones, computers, etc.)? ) From Canada to Chinese mainland?

How much to buy abroad is not a problem. As long as it is legally bought, no one will check you. The question is how to bring it back or send it back. According to the current regulations of domestic customs, every package with a value of more than 5,000 yuan is taxed (and the value is not calculated according to what you write, but judged by the customs according to the domestic market price of the goods). At present, the customs basically scans every package sent back to China by overseas express delivery. If it is suspected that the description value does not match the value of the items inside, it can be opened for inspection, so don't think about mailing luxury goods and expensive electronic products. It is very likely to be taxed, and it will be unprofitable to send them back in small quantities. Theoretically, all goods over 5,000 RMB brought back to China should be taxed, and every checked baggage should be scanned by a machine. Generally, people don't check what they have with them, but if they are in doubt, they will take it at random, so it depends on the probability. It should be possible to bring some yourself occasionally, but the customs will pay attention to it if the quantity and frequency are too high. Finally, the defendant may be smuggled. You can search the stewardess purchasing case (tried in 10, bringing luxury goods from South Korea to China for sale) and measure the risk yourself ... You said that there was a courier company, but it was brought back by illegal means (there are basically no courier companies that can help you with cheap transportation with tariffs, because everyone can find out the amount of tariffs, and they can't be lower than normal tariffs), so the safety is not fully guaranteed, and you won't advertise in the open (that's not waiting). It's hard for ordinary people to find it. You have to find someone familiar to find a relatively safe one.
