Import and export prohibitions: non compliance with licensing or standards triggers confiscation and significant penalties under customs law. Prohibited goods are those barred under the Customs Act or any other law; non fulfilment of licensing, registration, packaging or quality requirements renders consignments prohibited. The Central Government may declare specific imports or exports prohibited, and customs enforcement includes confiscation of goods imported or exported contrary to prohibitions and statutory penalties for improper importation or attempted improper exportation, with enhanced penalties applicable for prohibited items.
