I bought a watch in Switzerland, do I have to collect tax when I return home?

According to the "Measures of the Customs of the People's Republic of China*** and the State Customs on the Collection of Import Duties on Luggage Articles of Inbound Passengers and Personal Postal Articles", high-grade articles bought overseas, such as watches, cosmetics, jewelry and electrical appliances, are subject to import duties when entering the country.

Expanded Information

Calculation of Import Duty on Personal Effects:

Duty-paid price x import duty rate = amount of import duty payable

Duty-paid price: For example, if you buy an electric razor, and the actual price of the product is 1,300 yuan, and the duty-paid price table stipulates that the duty-paid price is 200 yuan, then it is not necessary for you to pay any import duty on the razor. The duty-paid price is 200 yuan, then your tax is calculated according to 200, and has nothing to do with the actual 1300 yuan you paid.

Import tariff rate: According to the duty-paid price list, the tax rate for electric shavers is 20%.

The amount of import tariffs payable = 200 * 20%, that is, $40 tariffs, but $40 does not exceed $50 tax exemption, so even if you are sampled and checked, you do not have to pay the tax, if you have a parcel with two electric shavers, then you have to pay $80 in taxes

The actual payment of $1300 is the same as that for the electric shavers. Reference:
