It depends on the country of importation and the type of product. For example, a customs clearance takes up to a week for cosmetics to clear, but it can take three months for agricultural products. Each country has its own set of regulations and procedures governing the importation of goods, so it's impossible to give a precise answer without knowing more about the specifics of your shipment. However, most shipments will clear customs within a few days or weeks. I hope your shipment arrives soon.
