Hi!
Commonly there should not be any difference in the form of such docs.
1/ Commercial invoice to be issued by the Seller in the name of the Buyer shown description and details of the goods as per contract/proforma invoice/LC terms, terms/basis of delivery, contract references, price and total amount payable, duly dated and signed&stamped. Other details to be inserted upon necessaty.
2/ Packing list may be issued in the same form as the invoice, bit not showing price and value of the goods. It may be dated and signed and stamped depending on necessety of this.
The main purpose of the P/L is to give Buyer detailed specification of what have been sent/delivered/loaded under appropriate shipping document.
Most of arabian countries/buyers are requesting for invoices to be legalized/certified/attested by chamber of commerce and/or appropriate consulate.
Otherwise they will pay penalty while import/customs clearance.
