A serial device server is usually quoted per chassis, with the port count of RS-232 or RS-485 called out on the same line. A USB dongle is quoted per piece, sometimes with a captive cable length in centimetres. Mixing those units makes a wholesale serial to ethernet adapter number look comparable to a laptop dongle when the hardware is not the same object.
Dimensions that matter on the serial chassis are width, depth, and whether the unit is a DIN-rail module or a desktop box. On a dongle, the dimension that blocks a neighboring port is the body width in millimetres. Ask the factory to state both the enclosure material and the connector, and to attach the drawing revision. A plastic shell and a metal shell can share a marketing name and still fail a different vibration question.
Quantity should name the unit: pieces, chassis, or a spare percentage you want held as a separate line. Destination is the US ship-to used for freight, not a slogan. If the serial side must stay isolated from the Ethernet ground, write that as an open test item rather than assuming the photo shows isolation.
The USB-C quote desk covers bus-powered dongles. This catalog keeps the serial form visible so a buyer can start from the chassis when that is the real job. Neither page stores inventory.
