Can anyone direct me to the laws and license requirements to bring carton's of US cigarettes into Belize? What is required? Any brokers advice or recommendations appreciated.

There are Cigarette Manufacturers in Belize so I am guessing as we see few US brands for sale here - no official knowledge - it will be highly regulated with permits required and difficult to get. Talk to Customs in Belize and talk to the highest ranking officer you can. I'm assumming you mean multiple cartoons rather than duty free personal consumption.
