A Bill of Lading is a legal document issued by a carrier to a shipper that details the type, quantity, and destination of the goods being carried. It serves as a shipment receipt when the carrier delivers the goods at the predetermined destination.

FOB is a shipping term that indicates when the ownership of goods is transferred from the seller to the buyer. In an FOB agreement, the seller is responsible for the goods until they are loaded on a shipping vessel; after that, the buyer assumes responsibility.

Door-to-door service means the freight company picks up the shipment from the origin and delivers it directly to the destination, rather than the customer having to arrange for transportation to and from ports or terminals.

The cost of freight shipping is determined by several factors including the mode of transportation (air, sea, road), weight and dimensions of the cargo, distance between origin and destination, and any special handling requirements.

Air freight is typically used for high-value, time-sensitive goods due to its speed and reliability. However, it can be more expensive than ocean freight. Ocean freight, on the other hand, is more cost-effective for larger, heavier shipments, but it takes longer.
