Hello forest.roses,
A commercial shipment is one where there is a transaction money involved. You just need to complete the export formalities (necessary documentation) and follow the RBI guidelines. These documentation are different depending upon the mode of shipping (through Pvt. Couriers, India Post etc).
RBI requires all this to ensure that the foreign currency entering India is against trade only and not an illegal / hawala transaction.
Customs ensure that correct Priced Item leaves the Country and PayPal from now on would certify through FIRC that foreign currency against such trades have been received by the Seller.
RBI would keep a check through IEC code entered at PayPal site for money received and through Copy of export documents submitted ..... to ensure there is no discrepancy.
