The main function of customs is to ensure the economic security of the country. The service acts as a kind of buffer to prevent smuggling and other illegal goods into the territory of the state.

All areas of activity are very important, but it is the most difficult to fight the smuggling of drugs, historical values, weapons. Although most loopholes employees have long known and actively work out, criminals do not get tired to come up with more sophisticated methods of crossing the border.

The profession of customs officer involves the ability to use all sorts of technical means to identify illegal items. Basically, their effect is reduced to enteroscopy, which is used to check large loads (cars, trailers, containers).

In addition to the direct control of the passage of goods at the border, customs officers are engaged in investigations, keep records of confiscated goods, engaged in analytical activities. Programmers, economists, and lawyers also work here.
