Clearance documents have to be filled in and submitted not only during customs check, but also before the goods are loaded onto the vessel. Many pieces of specific data elements are mandatory, and some freight shipping customs brokers are experienced in filling in these data to ensure that these data get to the relevant agencies on time.
Most freight shipping companies offer advisory and customer services on taxes, tariffs, duties and other miscellaneous fees. They update you regularly so that you can plan your shipments efficiently. They also advise on the right procedures to take, whether you meet all the required regulations or not, before your goods are all set to go.
