On board courier services in China typically do not provide direct assistance with customs duties or tax calculations. Their main role is to expedite the delivery of important documents, packages, or goods by hand-carrying them on commercial flights.
However, some on board courier services may offer additional services such as customs clearance or consultation through partnerships with customs brokers or logistics companies. These services can help individuals or businesses navigate customs procedures and ensure compliance with import/export regulations.
When it comes to customs duties and tax calculations, it is the responsibility of the shipper or receiver to accurately declare the value of the items being shipped and handle any associated taxes or duties. On board courier services may be able to provide general guidance or information regarding customs duties or tax calculations, but they typically do not extend direct support in this regard.
If individuals or businesses require specific assistance with customs duties or tax calculations, it is advisable to seek the expertise of professionals such as customs brokers, freight forwarders, or tax consultants who are familiar with the regulations and can provide accurate guidance based on the specific circumstances.
