If a customer separately arranges and pays for delivery of a taxable item by a third party, the seller of the item will only collect sales tax on its charge (see Delivery-only services, below).f the product or service being sold is not taxable, any charge to the customer for shipping or delivery is also not taxable. This also applies when the customer gives the seller a valid resale certificate or other exemption document.
1 Definition: The anode of a device is the terminal where current flows in from outside. The cathode of a device is the terminal where current flows out. This is illustrated in figure 1.  A useful mnemonic is ACID : Anode Current Into Device.
A cathode is mounted to the inside of the anodizing tank; the aluminum acts as an anode, so that oxygen ions are released from the electrolyte to combine with the aluminum atoms at the surface of the part being anodized.
