Dear mobilestore4u,
Thanks for the question. Please see below the response for your questions.
Point # 1. Forms required for certain location is a State requirement and is not dependent on the Logistics Service Providers or PowerShip. We encourage sellers to comply with the requirements to avoid potential delayed shipments to buyers.
Point # 2 - Surface mode is powered by BlueDart and there might be certain locations not enabled due to PIN serviceability
Point # 3 - If you wish to offer Surface only as a mode of shipping for sellers, you need to modify the Sell Your Item form and enable Surface as the Shipping method. In case this option is not selected, the item will by default be shipped through AIR. If you are unable to select Surface on such items, please send us the Category details and screen shot to inlogistics@ebay.com.
Regards,
Sameer
