What is the primary purpose of an import permit?

The primary purpose of an import permit is to authorize the entry of controlled or restricted goods into a country. Governments impose regulations on certain items due to concerns related to safety, health, environmental impact, or national security. An import permit serves as a formal approval that allows these specific goods to be imported legally, ensuring that the necessary checks and balances are in place before they enter the market. This process helps in managing and monitoring imports that may have potential implications for public welfare or trade policies.

While an import permit might indirectly affect other factors, such as compliance with local regulations or customs duties, its main function is centered around the authorization aspect concerning restricted items, making option B the most accurate.
