The partial shipment---part shipment---is allowed, unless otherwise stipulated in the L/C.
When shipments are made on different dates and/or different ports or points of origin, but the transport documents indicate the same destination and bear the same means of conveyance for the same journey, they are not regarded as covering partial shipments. Please see Case Sample: Non-Partial Shipment.
When shipments are made by post or by courier, if the post receipts or the courier's receipts bear the same date and place of dispatch and have been authenticated by any stamp, signature, mark, or label, they are not regarded as partial shipment.
