The documents required for air freight typically include the commercial invoice, packing list, air waybill (AWB), export license (if applicable), certificate of origin, and any specific documentation required by the destination country or airline. Additional documents may be needed depending on the nature of the goods and regulatory requirements.

Pre-requisites for ocean freight include the commercial invoice, packing list, bill of lading (B/L), export license (if applicable), certificate of origin, and any specific documentation required by the destination country or shipping line. Customs clearance documentation and compliance with international trade regulations are also essential pre-requisites for ocean freight shipments.

Air cargo charges for packaging can vary depending on the size, weight, and nature of the goods being shipped. While air freight rates are generally higher than ocean freight, the packaging charges themselves are typically not significantly higher. The cost of packaging is usually a small portion of the overall air freight charges.

The procedure for customs clearance involves several steps. Firstly, the necessary customs documents must be prepared and submitted, including the commercial invoice, packing list, and other relevant paperwork. Customs officials then review and verify the documents, assess the duties and taxes, and inspect the goods if necessary. Finally, the customs clearance process concludes with the release of the goods for delivery.
