A more thorough explanation:

A customs broker is a type of broker who prepares paperwork for the entry or clearance of ships, and for the import or export of goods. They act as intermediaries between importers or exporters and government agencies, such as customs officials.

For example, if a company wants to import goods from another country, they would hire a customs broker to help them navigate the complex regulations and paperwork required by the government. The customs broker would ensure that all necessary documents are filed correctly and on time, and that the goods are cleared through customs without any issues.

Customs brokers are important because they help facilitate international trade by ensuring that goods can move across borders smoothly and efficiently. Without customs brokers, it would be much more difficult and time-consuming for companies to import or export goods.
