Export documents certify the origin of merchandise and establish the route to destination. The following documents must be taken into account at the time of exporting:
Commercial Invoice: This is issued by the exporter once the sale to the importer is confirmed and must be included in the case file accompanying the cargo during the route from customs to customs.
Pro forma invoice: This provisional document is issued by the exporter for the purchaser to have the information of the complete purchase. The pro forma invoice can also be used to for sending samples with no commercial value, so the purchaser can apply for an import license or request credit. The pro forma invoice must contain all the elements of a commercial invoice.
Certificates of origin: These are documents to guarantee and define the origin of the merchandise to satisfy customs requisites, constituting a record which corroborates that the merchandise is completely obtained or if it underwent some transformation.
Different classifications of Bills of Lading:
- Maritime Shipping Bill of Lading: issued by the shipping company or its agent showing the merchandise has been approved for being transported to the port of reference on the ship as indicated. It serves as an acknowledgement of the conditions of the merchandise as received, as well as the transportation contract specifying the obligations of the parties and serving as a credit title allowing its holder to receive the transported merchandise.
- Air Bill of Lading: an air transportation document, registering the cargo to be transported by an airline, with conditions very similar to the maritime bill of lading
- Waybill: this is a document issued by the transportation company attesting to the receipt of the merchandise for transportation to the place agreed to under the conditions established therein.
Unified Customs Declaration: this summarizes the information generated by an international commercial transaction, covering the information of the merchandise (description, value, weight, framework, etc.), purchaser and seller.
Certificates according to the nature of the export: other documents may be needed depending on the merchandise: health certificates, phytosanitary certificates, certificates of no-objection, vehicle ownership titles, etc.
