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 duties on goods, which can affect their final price. When traveling, individuals must also follow customs regulations regarding personal items. This includes declaring items like gifts, food, or currency that exceed certain limits. Failure to comply can result in fines or confiscation of goods, making it essential for travelers to understand these rules before their journey.
