Customs regulations are rules set by governments to control the import and export of goods across borders. These regulations help ensure that items entering or leaving a country comply with safety, health, and legal standards. They also help collect taxes and prevent illegal activities, such as smuggling. When traveling, individuals must declare items they bring into a country, including gifts and personal belongings. Each country has specific limits on what can be brought in without paying duties. Understanding these regulations is essential for both travelers and businesses to avoid fines and ensure smooth transactions at customs checkpoints.
