What do I do if a portion of my shipment was left behind in the U.S.?

We will require the original invoice along with the product invoice that was left behind. A shortage letter from either the carrier or the shipper will be needed to explain what happened. Once we have this information we can use the same transaction that was used on the original shipment and provide to customs the documents. This will prove to customs that the GST was paid on the original shipment. However, a small brokerage fee will be charged to complete the paperwork.
