The procedure for assessment of customs duty in India involves the following steps: Classification of goods: The first step in assessing customs duty is to classify the goods being imported or exported into the appropriate customs tariff heading. This is done by identifying the correct Harmonized System of Nomenclature (HSN) code for the goods. The HSN code is a globally accepted system of classifying goods based on their nature, quantity, and value. Valuation of goods: The next step is to determine the value of the goods being imported or exported. The value of the goods is usually based on the transaction value, i.e., the price paid or payable for the goods. However, in certain cases, such as when the importer and exporter are related parties, the customs authorities may use other methods of valuation. Application of customs duty rates: Once the value of the goods has been determined, the customs duty rates applicable to the goods are applied. Customs duty rates can vary depending on the nature of the goods, the country of origin or destination, and the applicable laws and regulations. Calculation of customs duty: The customs duty payable is calculated by multiplying the value of the goods by the applicable customs duty rate. In addition to customs duty, other charges such as countervailing duty, anti-dumping duty, and safeguard duty may also be applicable depending on the nature of the goods and the applicable laws and regulations. It is important to note that the procedure for assessment of customs duty may vary depending on the nature of the goods, the country of origin or destination, and the applicable laws and regulations. It is advisable to consult with a customs broker or a trade expert to understand the exact procedure for assessing customs duty for specific goods being imported or exported.
