In order for the products to pass approved by customs and go for free circulation, they need to go through several steps. First, documents are prepared so that it can pass through customs for international shipping: customs price declaration of the product to be transported, regulation declaration of customs prices. These documents are essential in order for the product to pass through the customs control. The goods crossing the border are classified according to the HS code, and the conformity and hygiene certificates of all products and documents confirming the transportation process are required. Certain product categories are not allowed to be transported abroad. Customs duty must be paid after the required documents are obtained. The next step is to clear the goods from customs, which is under the tracking of the shipping company. After the relevant agreements and contracts are signed, the calculation of the customs payments of the transported products starts and at the last stage, export, import or transit arrangement is made.
