What obligations does a seller have under a shipment contract?

In a shipment contract, the seller has specific obligations focused on the delivery process. The primary duty is to deliver the goods to a carrier that has been chosen for shipping. This means that the seller must arrange for the transportation of the goods, effectively transferring the responsibility for the items to the carrier. Notification to the buyer about this delivery is also vital; the seller should inform the buyer that the goods have been handed over to the carrier. This notification helps the buyer track and receive their shipment, ensuring transparency in the transaction.

The other options do not accurately reflect the responsibilities outlined in a shipment contract. For instance, while sellers do need to deliver the goods, they are not responsible for ensuring that the goods arrive at the buyer's location—that responsibility typically lies with the carrier once the goods are transferred. Additionally, while some shipping costs may not fall under the seller's obligations, the seller may still incur costs prior to the transfer. Finally, while appropriate packaging is essential, especially for certain types of goods, it is not a specific obligation dictated by shipment contracts. Thus, the correct choice highlights the seller's essential duties regarding delivery to the carrier and appropriate notification to the buyer.
