What are areas where people can buy goods from other countries without paying extra taxes?

People can buy goods from other countries without paying extra taxes in several areas, such as through personal exemptions for imports, where small quantities of items can be brought in duty-free for personal use. Online marketplaces often facilitate international purchases that fall below a certain value threshold, exempting them from additional tariffs. Additionally, free trade zones and certain international agreements may allow for tax-free transactions on specific goods. However, these exemptions vary by country and depend on local customs regulations.
