Ryan, You need to look into the impact test, flammability and ignition/tracking properties, temperature index, enclosure opening requirements in the applicable safety standard. I assume you are using IEC/UL 60950-1. If you will be using conductive material to ensure you meet emc requirements, make sure you pick a material that has been previously evaluated/tested for use on polycarbonate material. If not previouly evaluated, your third party test house may require a special test under various environmental conditions to ensure that the material does not peel and short out electrical circuitry resulting in risk of electric shock, fire or energy hazard.

There will be some metalized shielding on the inside. I don’t have all the specification on the shielding properties at this time. The product is roughly a 1Ux12”x 12” ITE product AC or 48VDC ~35W power two port RJ45 Ethernet for UTP. FCC, UL, NEBS Type 2 and 4. I am concerned about the ESD and EMI aspects as well as other issues such as grounding. I will be interested in hearing any horror stories or outright restriction or test hurdles that maybe encountered.
