Firstly:                 

The exporter presents the application of origin (model 8-repeated) to issue the certificate of origin. The employer increase checks the certificate of customs measure after finishing the aviation exports or checking the customs release permission in shipping.
1- Bill of lading
2- Sale invoice.
3- The approval of the specific authority if it is available.
4- The exporter's admission on special publications about the percentage of the local product.
5- The certificate of origin (its type can be identified according to the import country. It should be written in English or in the language of the import country unless the credit doesn't include this).

It is important that the application's data and documents should be identical.

Secondly :

The certificate of origin can be issued before shipment, export and before completing the aforementioned documents. This is important to enable the exporter to ratify and send the certificate with the exported shipment. This requires getting an exception from the origin authority an presenting it with the other documents. He obliges to present the rest of documents later.

Thirdly :

 In all cases of issuing the certificate of origin, the general authority for controlling exports and imports demands an admission on the applicant (model 8). This model indicates that the applicant didn't issue the certificate of origin from this authority or from any other branch concerning this shipment. Anyway, the exporter should contact directly with the agent to enable himself knowing the progress of his success or what are the reasons of becoming hindered in the market.
