  • If you are not an existing client, please create a new account prior to your first submission.

  • If you are an existing client, please include your account number on all documents and correspondence.

Note: Each diamond parcel paper should be numbered based on the order of the list or Excel file. The accuracy and completeness of these documents are essential to avoid any potential loss of time and additional costs incurred during import and export.
