Most importers and exporters hire a freight forwarder or customs broker to pay the duties on their behalf, saving them the trouble of having to pay the duties themselves. If the importer manages the shipment themselves, they will usually receive an invoice detailing the duties once the shipment arrives in the country. These charges need to be paid before the goods are released for onward transportation. In some cases, the importer does not have to pay the import charges. This depends on the Incoterms (International Commercial Terms) agreed upon between the importer and the supplier (exporter).

Customs clearance is usually completed within minutes or hours, but may take days or weeks if documents are missing or the goods require inspection. In this case, the goods will be detained until the necessary documents are provided or customs officials complete the inspection.

The number of documents required for customs clearance varies from country to country, but most countries require the following: * Export Documents * Purchase order from buyer * Sales invoice * Packing list * Bill of lading or airway bill * Certificate of origin Any other documents required by the buyer or listed in the letter of credit from the financial institution * Import Documents * Purchase Order * Supplier’s Sales Invoice * Bill of Lading or Airway Bill * Packing List * Certificate of Origin * Any other documents or letter of credit terms required by the buyer If you encounter any problems during customs clearance, please contact us and we will help you.

Machines in stock will be shipped within 2-10 working days. In case of special circumstances, we will contact you to discuss solutions.

The future shipping date will be determined based on the manufacturer’s information. We will mark the estimated delivery time on the product page for reference. We will arrange shipment as soon as we receive the machine.

If any abnormality occurs during the logistics process, please contact our sales representative or consult the logistics company for verification.

Although there is no warranty or after-sales service for second-hand machines, we will send you the testing video and photos of the package inside the parcel to ensure that there is no problem with the machine before shipping.
