3. Reading: The customs’ work includes the following:

1. Duty collection

The assessment and collection of duties and taxes have always been one of the main functions of the customs service. In fact, collection of the revenue is the responsibility with which the customs usually started. Throughout its history the customs has suppliedthe federal budget with the revenue necessary for investment in the economy and in the country’s basic infrastructure, i.e. new schools, roads, hospitals.

2. Classification

Merchandise classification is the foundation on which duty collection occurs. All goods entering the country should be classified by use of the established numerical coding system. Most countries are now adopting the Harmonized System of Classification which, in case of uniform application, can help improve the classification of goods and prevent losses of duty collection.

​3. Appraisement

Cargo shipments entering the country are to be supplied with the necessary documents, for example, commercial invoices, certificates of quality, certificatesoforigin and others. The cargo declaration is a basis for goodsvaluation and assessment of duty. Undervaluationcan result in underpayment of duties.

4. Cargo and Passenger inspection

Effective passenger and baggage control is necessary to collect proper duty and to prevent smuggling. Baggage is checked  for concealment; by X-ray or opening it. Cargo shipments are to be inspected for duty collection and anti-smuggling purposes. Various inspectional techniques and devices can help release merchandise quicker, with less damage and also result in increased seizures of prohibited items.

5. Investigation

Investigation of customs violations is performed to target the more sophisticated violators of customs laws and regulations. The full range of customs violations can be investigated: the smuggling of merchandise, narcotics, arms and ammunition as well as commercial fraud, currency violations and money laundering, internal corruption, infringement of trademark and intellectual property rights (IPR) etc.

Answer the following questions:

1. Where does the duty collected go?

2. What documents must accompany the cargo?

3. What customs violations can you name?
