2, the export of goods need to go through two hurdles: the export declaration of the country of origin and the import clearance of the destination country. So "double clear" is to include import and export customs clearance. That is to say, you give the goods to us, we are responsible for arranging the trailer, customs clearance and shipment. After the ship arrives at the destination port, we will be responsible for the exchange of documents and customs clearance. If it is "double clearing and tax inclusive door-to-door", it means that after arriving at the port of destination, we will arrange delivery to the hands of the addressee. The literal meaning of "tax inclusive" is clearer, that is, the goods reach the destination without having to pay any fees.
