Bonded goods are products for which customs duty has not yet been paid. To ensure that these goods are properly managed until the duty is paid, they must be stored in bonded warehouses, which are facilities that are supervised by customs authorities. Bonded warehouses allow businesses to import goods and delay payment of duties until the products are ready to be released onto the market. This can be useful for businesses that need to import goods for a specific project or that want to take advantage of fluctuating currency exchange rates.
