Customs clearance is the process of getting goods officially approved by the customs authorities of a country before they can be imported or exported. It involves preparing and submitting documents such as invoices, shipping forms, and any applicable taxes or duties. Customs officers inspect the goods and paperwork to ensure compliance with local laws and regulations.

Once the clearance is completed, the goods can move across borders freely. This step is crucial for international trade, as it ensures the correct tariffs are applied and that no prohibited items are brought into or out of the country.
