Customs Law refers to the regulations and legal frameworks governing the import and export of goods across international borders. It ensures that countries can control what enters and leaves their territories, protecting national security, public health, and the economy. Customs laws also involve the assessment of duties and taxes on goods, which helps generate revenue for governments. Additionally, Customs Law includes compliance with international agreements and trade treaties, which can affect tariffs and trade practices. Customs authorities are responsible for enforcing these laws, inspecting shipments, and preventing smuggling or illegal trade activities.
